Alarm Troubleshooting


This chapter gives a list of alarm descriptions, default severities, and troubleshooting procedures for all alarms that can be resolved in the Cisco ONS 15454 SDH system. See Table 1-1 for an alphabetical list of alarms that appear on the ONS 15454 SDH. See Table 1-2 for a list of alarms organized by alarm type.

This chapter provides a comprehensive list of alarm conditions with severities of Critical, Major, or Minor. All listed alarm severities are active card defaults, if applicable. Standby card default severities are always Minor, Non-service affecting (NSA). The default standby severity for conditions with a severity of Not alarmed (NA), Non-service affecting is NA, NSA. The default standby severity for conditions with a severity of Not reported (NR), NSA is NR, NSA. The procedure to correct an alarm applies to the Cisco Transport Controller (CTC) version of that alarm.

1.3 Trouble Notifications

The ONS 15454 SDH uses ITU-T x.733-compliant categories to characterize alarm levels. In CTC, the Critical, Major, and Minor ONS 15454 SDH alarms are reported in the Alarms tab. This tab contains alarms such as loss of signal (LOS) indicating problems a user must correct. The ONS CTC Conditions tab contains ONS 15454 SDH conditions as well as alarms. If a condition is not listed in the Alarms tab as well, it is a notification and does not require user action.

Alarms are further-divided into Service-Affecting (SA) and NSA status. An SA failure affects a provided service or the network's ability to provide service. For example, a missing transmitter (TRMT-MISS) alarm is characterized as an SA failure. TRMT-MISS occurs when the cable connector leading to a port on an active E1-N-14 card is removed. This affects a provided service, because traffic switches to the protect card. The high temperature (HITEMP) alarm, which means the ONS 15454 SDH is hotter than 50 degrees Celsius (122 degrees Fahrenheit), is also an SA failure. For example, although a particular E1 port may not be affected, a high temperature affects the network's ability to provide service.

1.3.1 Conditions

When an SA failure is detected, the ONS 15454 SDH also sends an alarm indication signal (AIS) downstream. When it receives the AIS, the receiving node sends a remote failure indication (RFI) upstream. AIS and RFI belong in the conditions category and are shown on the Conditions tab of the ONS 15454 SDH. The condition reporting is not ITU-compliant.

1.3.2 Severities

The ONS 15454 SDH uses ITU severities: Critical (CR), Major (MJ), and Minor (MN). Critical indicates a severe, service-affecting alarm that needs immediate correction. Major is still a serious alarm, but the failure has less of an impact on the network.

Minor alarms, such as Fast Start Synchronization (FSTSYNC), do not have a serious affect on service. FSTSYNC lets you know that the ONS 15454 SDH is choosing a new timing reference because the old reference failed. The loss of the prior timing source is something a user needs to look at, but it should not disrupt service.

The ONS 15454 SDH uses standard severity reporting that is ITU-compliant. A user may customize ONS 15454 SDH alarm severities with the alarm profiles feature. For additional information about alarm severities, refer to the Cisco ONS 15454 SDH Installation and Operations Guide. This chapter lists the default alarm severity for the active reporting card, if applicable.

1.4 Safety Summary

This section covers safety considerations to ensure safe operation of the ONS 15454 system. Personnel should not perform any procedures in this manual unless they understand all safety precautions, practices, and warnings for the system equipment. Some troubleshooting procedures require installation or removal of cards. In these instances, users should pay close attention to the following caution:


Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when removing or installing cards.

Some troubleshooting procedures require installation or removal of optical (STM) cards. In these instances, users should pay close attention to the following warnings:


Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.



Warning Class 1 laser product.



Warning Class 1M laser radiation when open. Do not view directly with optical instruments.


1.5 Alarm Procedures

This section lists alarms alphabetically. Each alarm or condition topic gives the severity, description and troubleshooting procedure.

1.5.1 APSB

Minor, Non-service affecting

The channel byte failure alarm occurs when line terminating equipment detects protection-switching byte failure in the incoming automatic protection-switching (APS) signal. This happens when an inconsistent APS byte or invalid code is detected. Some older, non-Cisco SDH nodes send invalid APS codes if configured in a 1+1 protection scheme with newer SDH nodes, such as the ONS 15454 SDH. These invalid codes will raise an APSB on an ONS node.

Procedure: Clear the APSB Alarm


Step 1 Examine the incoming SDH overhead with an optical test set to confirm inconsistent or invalid K bytes.

Step 2 If corrupted K bytes are confirmed and the upstream equipment is functioning properly, the upstream equipment may not interoperate effectively with the ONS 15454 SDH. For ONS 15454 SDH protection switching to operate properly, the upstream equipment may need to be replaced.


1.5.2 APSCDFLTK

Minor, Non-service affecting

The default K byte received alarm occurs when an MS-SPRing is not properly configured. For example, it occurs when a four-node MS-SPRing has one node configured as an SNCP ring. A node in an SNCP or 1+1 configuration does not send the two valid K1/K2 APS bytes anticipated by a system configured for MS-SPRing. One of the bytes sent is considered invalid by the MS-SPRing configuration. The K1/K2 byte is monitored by receiving equipment for link-recovery information. The alarm can also be caused when a new node is added but a new ring map has not been accepted.


Warning The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.



Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.


Procedure: Clear the APSCDFLTK Alarm


Step 1 Prior to accepting a new mapping table, verify that each node has a unique node ID number:

a. Log into a node on the ring.

b. Click the Provisioning > Ring tabs.

c. Record the node ID number.

d. Repeat Steps a - c for all nodes in the ring.

e. If two nodes have the same node ID number, change one node ID number so that each has a unique node ID.

f. Click Apply.

Step 2 Verify correct configuration of East port and West port optical fibers by following the procedure in the "EXCCOL" section.

Step 3 If the ring is a four-fiber MS-SPRing, make sure that each protect fiber is connected to another protect fiber and each working fiber is connected to another working fiber. The software does not report any alarm if there is a working fiber incorrectly attached to a protect fiber.

Step 4 Click Yes to accept the ring map.

Step 5 If the alarm does not clear, check the ring map for each ONS 15454 SDH in the network and verify that each node is visible to the other nodes:

a. At the node (default) view, click the Provisioning > Ring tabs.

b. Highlight an MS-SPRing.

c. Click Ring Map.

d. Verify that each node that is part of the ring appears on the ring map with a node ID and IP address.

e. Click Close.

Step 6 If nodes are not visible, ensure that Section Data Communications Channel (SDCC) terminations exist on each node:

a. Click the Provisioning > SDH DCC tabs.

b. Click Create.

c. Click the STM-N card that links to the adjacent node.

d. Click OK.

Step 7 If the alarm still does not clear, login to http://www.cisco.com/tac for more information or login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country.


1.5.3 APSC-IMP

Minor, Non-service affecting

An improper APS code alarm indicates invalid K bytes. This alarm occurs on STM-N cards in an MS-SPRing configuration. The receiving equipment monitors K bytes or K1 and K2 APS bytes for an indication to switch from the working card to the protect card or vice versa. K1/K2 bytes also contain bits that tell the receiving equipment whether the K byte is valid. APSC-IMP occurs when these bits indicate a bad or invalid K byte. The alarm clears when the node receives valid K bytes.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the APSC-IMP Alarm


Step 1 To determine the validity of the K byte signal, examine the received signal. Use an optical test set capable of viewing SDH overhead.

Step 2 If the K byte is invalid, the problem lies in upstream equipment and not in the reporting ONS 15454 SDH. Troubleshoot the appropriate upstream equipment.

Step 3 If the K byte is valid, verify that each node has a ring ID that matches the other node ring IDs:

a. Using CTC, log into a node on the ring.

b. Click the Provisioning > Ring tabs.

c. Record the ring ID number.

d. Repeat Steps a - c for all nodes in the ring.

Step 4 If a node has a ring ID number that does not match the other nodes, change the ring ID number of that node to match the other nodes in the ring.

Step 5 Click Apply.


1.5.4 APSCINCON

Minor, Service-affecting

An inconsistent APS code is present. The SDH overhead contains K1/K2 APS bytes that notify receiving equipment, such as the ONS 15454 SDH, to switch the SDH signal from a working to a protect path. An inconsistent APS code occurs when three consecutive frames do not contain identical APS bytes. Inconsistent APS bytes give the receiving equipment conflicting commands about switching.

Procedure: Clear the APSCINCON Alarm on an STM-N Card in an MS-SPRing


Step 1 Look for other alarms, especially LOS, loss of frame (LOF) or AIS. Clearing these alarms clears the APSCINCON alarm.

Step 2 If an APSINCON alarm occurs with no other alarms, login to http://www.cisco.com/tac for more information or login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country.


1.5.5 APSCM

Major, Service-affecting

The APS channel mismatch alarm occurs when the ONS 15454 SDH expects a working channel but receives a protection channel. In many cases, the working and protection channels are crossed and the protection channel is active. If the fibers are crossed and the working line is active, the alarm will not occur. This alarm is raised in a 1+1 configuration. The APSCM alarm only occurs on the ONS 15454 SDH when 1+1 bidirectional protection is used on STM-N cards in a 1+1 configuration.


Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.



Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the APSCM Alarm


Step 1 Verify that the working-card channel fibers connect directly to the adjoining node working-card channel fibers.

Step 2 Verify that the protect-card channel fibers connect directly to the adjoining node protect-card channel fibers.


1.5.6 APSCNMIS

Major, Service-affecting

The node ID mismatch alarm raises when the source node ID contained in the K2 byte of the APS channel being received is not present in the ring map. This alarm may occur and clear when an MS-SPRing is being provisioned. If so, the user can disregard the temporary occurrence. If the APSCNMIS is raised and stays, the alarm clears when a K byte with valid source node ID is received.

Procedure: Clear the APSCNMIS Alarm


Step 1 Verify that each node has a unique node ID number:

a. Click the Provisioning > Ring tabs.

b. Highlight an MS-SPRing.

c. Click Ring Map.

d. If the Node ID column contains any two nodes with the same node ID listed, record the repeated node ID.

e. Click Close on the Ring Map dialog box.

Step 2 If two nodes have the same node ID number, change one node ID number so that each node has a unique node ID:

a. Display the network view.

b. Log into one of the nodes that uses the repeated node ID recorded in Step 1.


Note If the node names shown on the network view do not correlate with the node IDs, log into each node and click the Provisioning > Ring tabs. This screen displays the node ID of the node you are logged into.


c. Click the node ID table cell to reveal a pull-down menu.

d. Select a unique node ID from the pull-down menu and click Apply.


Note Locking out and clearing the lockout on a span causes the ONS 15454 SDH to generate a new K byte. The APSCNMIS alarm clears when the node receives a K byte containing the correct node ID.


Step 3 If the alarm does not clear, lockout a span on the ring and then clear the lockout:

a. Click the Maintenance > Ring tabs.

b. Click the table cell under the West Switch heading to reveal the pull-down menu.

c. Select LOCKOUT SPAN and click Apply.

d. Click OK in the MS-SPRing operation dialog box.

e. Click the same table cell under the West Switch heading to reveal the pull-down menu.

f. Select CLEAR and click Apply.

g. Click OK on the MS-SPRing operations dialog box.


1.5.7 AU-LOP

Critical, Service-affecting

An administration unit loss of pointer (LOP) alarm applies to optical cards. It is raised when the first payload pointer is not synchronized according to the system clock.


Warning The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.



Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.


Procedure: Clear the AU-LOP Alarm


Step 1 Check for LOS on the reporting card.

Step 2 On the card raising the alarm, check whether attenuation is present on the input fiber cable.

Step 3 Check signal level on the input fiber with the attenuator (if present).

Step 4 If fiber signal level with attenuator is below the correct threshold, remove the attenuator and check signal level again.

Step 5 If the signal level is still low, clean both ends of the fiber cable connection:

a. Clean the fiber cable ends according to local site practice.

b. If no local practice exists, use a CLETOP Real-Type or equivalent fiber-optic cleaner and follow the instructions accompanying the product.

Step 6 Clean the far-end optical fiber cable ends:

a. Clean the fiber cable ends according to local site practice.

b. If no local practice exists, use a CLETOP Real-Type or equivalent fiber-optic cleaner and follow the instructions accompanying the product.

Step 7 If error remains, check for a timing alarm by following the procedure in the "SYNCPRI" section.


1.5.8 AUTOLSROFF

Critical, Service-affecting

The automatic laser off alarm is raised when the OC192 LR/STM64 LH 1550 card temperature exceeds 90 degrees Celsius. The internal equipment automatically shuts down the OC192 LR/STM64 LH 1550 laser when the card temperature rises to prevent the card from self-destructing.


Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.



Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.


Procedure: Clear the AUTOLSROFF Alarm


Step 1 Read the temperature displayed on the ONS 15454 SDH LCD front panel.

Step 2 If the temperature of the ONS 15454 SDH exceeds 90 degrees Celsius, complete the procedure in the "Clear the HITEMP Alarm" section.

Step 3 If the temperature of the ONS 15454 SDH is below 90 degrees Celsius, replace the OC 92 LR/STM64 LH 1550 card.


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.


Step 4 Login to http://www.cisco.com/tac for more information or login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country and discuss the case and if necessary open a returned materials authorization (RMA) on the original OC 92 LR/STM64 LH 1550 card.


1.5.9 AUTORESET

Minor, Non-service affecting

The automatic system reset alarm occurs when a card is performing an automatic warm reboot. An AUTORESET occurs when you change an IP address or perform any other operation that causes an automatic card-level reboot.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the AUTORESET Alarm


Step 1 Check for additional alarms that may have triggered an automatic reset.

Step 2 If the card automatically resets more than once a month with no apparent cause, replace it with a new card.


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.10 AUTOSW-LOP-SNCP

Minor, Service-affecting

An automatic SNCP switch caused by an LOP alarm indicates that automatic SNCP protection switching took place because of the LOP alarm. The SNCP is configured for revertive switching and will switch back to the working path after the fault clears.

Procedure: Clear the AUTOSW-LOP Alarm


Step 1 Verify the cabling and physical connections on the reporting card.

Step 2 Perform a soft reset on the reporting card:

a. Display the CTC node view.

b. Position the cursor over the slot reporting the alarm.

c. Right-click to choose RESET CARD.

Step 3 Do a manual switch (side switch) to move traffic away from the card:

a. At the node view, click the Maintenance > Protection tabs.

b. Double-click the protection group that contains the reporting card.

c. Click the protect/standby card of the selected groups.

d. Click Manual and OK.


Note If you do not have a protect card for the reporting card, create a new circuit on the reporting card to achieve the same effect.


Step 4 Clear the manual switch:

a. At the node view, click the Maintenance > Protection tabs.

b. Double-click the protection group that contains the reporting card.

c. Highlight either selected group.

d. Click Clear and click YES at the confirmation dialog box.

Step 5 If the alarm persists, the problem is at the far-end node. Verify the stability of the cabling and physical connections that connect to the far-end card.

Step 6 Do a soft reset on the far-end card:

a. Display the CTC node view.

b. Position the cursor over the slot reporting the alarm.

c. Right-click and choose RESET CARD.

Step 7 Perform a soft reset on the reporting card:

a. Display the CTC node view.

b. Position the cursor over the slot reporting the alarm.

c. Right-click and choose RESET CARD.

Step 8 Switch from the far-end working card to the far-end protect card.

Step 9 If the alarm persists, replace the far-end card.


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.11 AUTOSW-UNEQ-SNCP

Minor, Service-affecting

An automatic SNCP switch caused by UNEQ alarm indicates that automatic SNCP protection switching took place because of an UNEQ alarm. The SNCP is configured for revertive switching and will switch back to the working path after the fault clears.


Warning The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.



Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.


Procedure: Clear the AUTOSW-UNEQ Alarm


Step 1 Display the CTC network view and right-click the span reporting AUTOSW-UNEQ.

Step 2 Select Circuits from the menu.

Step 3 If the specified circuit is a low-order path tunnel, check for low-order paths assigned to the tunnel.

Step 4 If the low-order path tunnel does not have assigned low-order paths, delete the low-order path tunnel from the list of circuits.

Step 5 If you have complete visibility to all nodes, check for incomplete circuits such as stranded bandwidth from circuits that were not deleted completely.

Step 6 If you find incomplete circuits, verify whether they are working circuits and if they are still passing traffic.

Step 7 If the incomplete circuits are not needed or are not passing traffic, delete them and log out of CTC. Log back in and check for incomplete circuits again. Recreate any needed circuits.

Step 8 Verify that all circuits terminating in the reporting card are active:

a. Click the Circuits tab.

b. Verify that the State column lists the port as ACTIVE.

c. If the State column lists the port as INCOMPLETE, and the INCOMPLETE does not change after a full initialization, login to http://www.cisco.com/tac for more information or login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country.

Step 9 After you determine that the port is active, verify the signal source received by the card reporting the alarm.

Step 10 Check the far-end STM-N card that provides payload to the card.

Step 11 Verify the far-end cross-connect between the STM-N card and the E-N card.

Step 12 Clean the far-end optical fiber cable ends:

a. Clean the fiber cable ends according to local site practice.

b. If no local practice exists, use a CLETOP Real-Type or equivalent fiber-optic cleaner and follow the instructions accompanying the product.


Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.



1.5.12 BKUPMEMP

Critical, Non-service affecting

The BKUPMEMP alarm refers to a problem with the TCC-I card flash memory. The alarm occurs when the TCC-I card is in use and has one of four problems: the flash manager fails to format a flash partition; the flash manager fails to write a file to a flash partition; there is a problem at the driver level, or the code volume fails cyclic redundancy checking (CRC). CRC is a method to check for errors in data transmitted to the TCC-I. The BKUPMEMP alarm will also raise the EQPT alarm. In this instance, use the following procedure to clear the BKUPMEMP and the EQPT alarm.

Procedure: Clear the BKUPMEMP Alarm


Step 1 Verify that both TCC-I cards are powered and enabled by confirming lit ACT/STBY LEDs on the TCC-I cards.

Step 2 Reset the active TCC-I card to make the standby TCC-I card active:

a. In CTC, display the node view.

b. Position the cursor over the active TCC-I card slot.

c. Right-click and choose RESET CARD.

Step 3 If the alarm clears, reseat the old TCC-I and allow it to boot up completely.

b. Position the cursor over the active TCC-I card slot.

c. Right-click and choose RESET CARD.

Step 5 If the alarm reappears after you perform the switch, replace the TCC-I card:

a. Open the card ejectors.

b. Slide the card out of the slot.

c. Open the ejectors on the replacement card.

d. Slide the replacement card into the slot along the guide rails.

e. Close the ejectors.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.13 CARLOSS (E-Series)

Major, Service-affecting

A carrier loss on the LAN alarm is the data equivalent of an SDH LOS alarm. The Ethernet card has lost its link and is not receiving a valid signal. The most common causes of this alarm are a disconnected cable or an improperly installed Ethernet card. Ethernet card ports must be enabled (put in service) for CARLOSS to occur. CARLOSS is declared after no signal is received for approximately 2.5 seconds.

This alarm also occurs after the restoration of a node database. In this instance, the alarm will clear in approximately 30 seconds after spanning-tree protection reestablishes. This applies to the E-series Ethernet cards, but not to the G1000-4 card. The G1000-4 card does not use spanning tree protocol (STP) and is unaffected by STP reestablishment.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the CARLOSS Alarm (E Series)


Step 1 Verify that the Ethernet cable is properly connected and attached to the correct port.

Step 2 Verify that the Ethernet cable connects the card to another Ethernet device and is not misconnected to an STM-N card.

Step 3 Check that the transmitting device is operational. If not, troubleshoot the device.

Step 4 Using a test set, determine that a valid signal is coming into the Ethernet port.

Step 5 If a valid Ethernet signal is not present and the transmitting device is operational, replace the Ethernet cable connecting the transmitting device to the Ethernet port.

Step 6 If a valid Ethernet signal is present, physically reseat the Ethernet card.

Step 7 If the alarm does not clear, replace the Ethernet card:


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.

a. Open the card ejectors.

b. Slide the card out of the slot.

c. Open the ejectors on the replacement card.

d. Slide the replacement card into the slot along the guide rails.

e. Close the ejectors.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.


Step 8 If a CARLOSS alarm repeatedly appears and clears, examine the layout of your particular network to determine whether the Ethernet circuit is part of an Ethernet manual cross-connect. If the reporting Ethernet circuit is part of an Ethernet manual cross-connect, then the reappearing alarm may be a result of mismatched circuit sizes in the manual cross-connect setup. If the Ethernet circuit is not part of a manual cross-connect, these steps do not apply.


Note An Ethernet manual cross-connect is used when third party equipment sits between ONS 15454 SDHs, and the OSI/TARP-based equipment does not allow tunneling of the ONS 15454 SDH TCP/IP-based Data Communications Channel (DCC). To circumvent a lack of continuous DCC, the Ethernet circuit is manually cross-connected to a channel continuing through the non-ONS network.


a. Right-click anywhere on the row of the CARLOSS alarm.

b. Click the Select Affected Circuits popup that appears.

c. Record the information in the type and size columns of the highlighted circuit.

d. From the examination of the layout of your particular network, determine the ONS 15454 SDH and card that host the Ethernet circuit at the other end of the Ethernet manual cross-connect.

e. Log into the ONS 15454 SDH at the other end of the Ethernet manual cross-connect.

f. Double-click the Ethernet card that is part of the Ethernet manual cross-connect.

g. Click the Circuits tab.

h. Record the information in the type and size columns of the circuit that is part of the Ethernet manual cross-connect. This circuit will connect the Ethernet card to an STM-N card on the same node.

i. Determine whether the two Ethernet circuits on each side of the Ethernet manual cross-connect have the same circuit size from the circuit size information you recorded.

j. If one of the circuit sizes is incorrect, navigate to the incorrectly configured circuit.

k. Click the incorrectly configured circuit to highlight it and click Delete.

l. Click Yes at the Delete Circuit dialog box, and OK at the Confirmation dialog box.

m. Reconfigure the circuit with the correct circuit size. Refer to the Cisco ONS 15454 SDH Installation and Operations Guide for procedures to provision Ethernet manual cross-connects.


1.5.14 CARLOSS (EQPT)

Minor, Non-service affecting

This carrier loss alarm means the ONS 15454 SDH and the workstation hosting CTC do not have a TCP/IP connection. It is a problem involving the LAN or data circuit used by the RJ-45 connector on the TCC-I card or the LAN backplane pin connection on the back of the ONS 15454 SDH. It does not involve an Ethernet circuit connected to a port on Ethernet card. The problem is in the connection (usually a LAN problem) and not the CTC or the ONS 15454 SDH.

Procedure: Clear the CARLOSS Alarm (EQPT)


Step 1 Verify connectivity by pinging the ONS 15454 SDH that is reporting the alarm:

a. If you are using a Microsoft Windows operating system, from the Start Menu choose Programs > Command Prompt.

b. If you are using a Sun Solaris operating system, from the Common Desktop Environment (CDE) click the Personal Application tab and click Terminal.

c. For both the Sun and Microsoft operating systems, at the prompt type:

 
ping [ONS 15454 SDH IP address]  
For example, ping 192.1.0.2

If the workstation has connectivity to the ONS 15454 SDH, it displays "reply from [IP Address]" after the ping. If the workstation does not have connectivity, a "Request timed out" message displays.

Step 2 If the ping is successful, an active TCP/IP connection exists. Restart the CTC.

Step 3 If you are unable to establish connectivity, perform standard network/LAN diagnostics. For example, trace the IP route, check cables, and check any routers between the node and CTC.


1.5.15 CONTBUS-A

Major, Non-service affecting

The communication failure TCC-I A to shelf slot alarm indicates the TCC-I card in Slot 7 has lost communication with a line card. Cards require frequent communication with the TCC-I card because the TCC-I performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SDH DCC termination, system fault detection, and other operations for the ONS 15454 SDH. The TCC-I card also ensures that the system maintains timing requirements.

The CONTBUS-A alarm can appear briefly when the ONS 15454 SDH switches to the standby TCC-I card. In this instance, the alarm clears after the cards establish communication with the new primary TCC-I card. In cases where the alarm persists, the problem lies in the physical path of communication from the TCC-I to the reporting card. The physical path of communication includes the TCC-I card, the card in Slot X and the backplane.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the CONTBUS-A Alarm


Step 1 Ensure the reporting card is physically present. Record the card type.

Step 2 Click the Inventory tab to reveal the provisioned type. If the actual card type and the provisioned card type do not match, complete the procedure in the "MEA (EQPT)" section.

Step 8 If the alarm reappears when the TCC-I in Slot 7 reboots as the active TCC-I, the TCC-I card in Slot 7 is defective and must be replaced.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.17 CONTBUS-B

Major, Non-service affecting

The communication failure TCC-I to shelf communication failure alarm indicates the TCC-I card in Slot 11 lost communication with a line card. Cards require frequent communication with the TCC-I card, because the TCC-I card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SDH DCC termination, and system fault detection among other operations for the ONS 15454 SDH. The TCC-I card also ensures that the system maintains timing requirements.

This alarm may appear briefly when the ONS 15454 SDH switches over to the protect TCC-I card. In this instance, the alarm clears after the other cards establish communication with the new primary TCC-I card. In cases where the alarm persists, the problem lies in the physical path of communication from the TCC-I card to the reporting card. The physical path of communication includes the TCC-I card, the card in Slot X, and the backplane.

1.5.26 EOC

Major, Non-service affecting

The termination failure SDCC alarm means the ONS 15454 SDH has lost the DCC. The DCC is three bytes, D1 through D3, in the SDH overhead. The bytes convey information about Operation, Administration, Maintenance, and Provisioning (OAM&P). The ONS 15454 SDH uses the DCC on the SDCC to communicate network management information.


Warning The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.



Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning Invisible laser radiation may be emitted from the end of unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.



Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the EOC Alarm


Step 1 If an LOS alarm is also reported, perform the "Clear the LOS Alarm on an STM-N Card" procedure.

Step 2 On the node reporting the alarm, check the physical connections from the cards to the fiber cables that are configured to carry DCC traffic.

Step 3 Verify that both ends of the fiber span have in-service ports by checking that the ACT LED on each STM-N card is illuminated.

Step 4 Verify that the DCC is provisioned for the ports at both ends of the fiber span:

a. Under the node view, click the Provisioning > SDH DCC tabs.

b. If the slot and port are listed under SDCC Terminations, the DCC is provisioned.

c. If the slot and port are not listed under the SDCC terminations, click Create.

d. Click the STM-N card that links to the adjacent node.

e. Click OK.

f. Repeat Steps a - e at the adjacent nodes.

Step 5 Verify that the STM-N port is active and in service:

a. Confirm that the STM-N card shows a green LED by viewing CTC or viewing the physical card. A green LED indicates an Active card. A yellow LED indicates a Standby card.

b. To determine whether the STM-N port is in service, double-click the card in CTC to display the card-level view.

c. Click the Provisioning > Line tabs.

d. Verify that the Status column lists the port as In Service.

e. If the Status column lists the port as Out of Service, click the column and select In Service.

f. Click Apply.

Step 6 With a test set, check for signal failures on fiber terminations.


Caution Using a test set will disrupt service on the STM-N card. It may be necessary to manually switch traffic carrying circuits over to a protection path.

Step 7 Measure power levels to verify that the budget loss is within the parameters of the receiver.

Step 8 Ensure that fiber cable connectors are securely fastened and properly terminated.


Caution Resetting the active TCC-I can result in loss of traffic.

Step 9 Reset the active TCC-I by performing the "Reset the TCC-I using a Card Pull" procedure on page 4-5. Resetting the active TCC-I switches the traffic to the standby TCC-I. If the alarm clears when the ONS 15454 SDH switches to the standby TCC-I, the user can assume that the original active TCC-I is the cause of the alarm.

Step 10 Replace the original active TCC-I with a new TCC-I card.

Step 11 Delete and recreate the problematic SDCC termination:

a. Click the Provisioning > SDH DCC tabs.

b. Highlight the problematic SDCC termination.

c. Click Delete.

d. Click Yes at confirmation dialog box.

Step 12 Verify that both ends of the SDCC have been recreated at the optical ports.

Critical, Service-affecting

An equipment failure alarm indicates that a hardware failure has occurred on the reporting card. If the EQPT alarm is raised with a BKUPMEMP alarm, complete the "BKUPMEMP" procedure. This procedure will also clear the EQPT alarm.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the EQPT Alarm


Step 1 Perform a software reset on the reporting card:

a. Display the CTC node view.

b. Position the CTC cursor over the slot reporting the alarm.

c. Right-click RESET CARD.

Step 2 If the software reset fails to clear the alarm, physically reseat the card.

Step 3 If the physical reseat of the card fails to clear the alarm, replace the card.


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.28 EQPT-MISS

Critical, Service-affecting

The replaceable equipment unit is missing alarm is reported against the fan-tray assembly unit. It indicates that a replaceable fan-tray assembly unit is missing or not fully inserted.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the EQPT-MISS Alarm


Step 1 If the alarm is reported against the fan object, check that the fan-tray assembly is present.

Step 2 If no fan-tray assembly is present, use the retractable handles embedded in the front of the fan tray to pull the fan-tray assembly forward several inches, push the fan-tray assembly firmly back into the ONS 15454 SDH shelf assembly, and close the retractable handles.

Step 3 If no fan-tray assembly is present, obtain a fan-tray assembly and refer to the fan-tray assembly installation information in the Cisco ONS 15454 SDH Installation and Operations Guide.


1.5.29 E-W-MISMATCH

Major, Service-affecting

A procedural error misconnect East/West direction alarm occurs when nodes in a ring have an East slot/port misconnected to another East slot/port or a West slot/port misconnected to another West slot/port. In most cases, the user did not connect the fiber cables correctly, or the ring provisioning plan was flawed. You can physically reconnect the fiber cable to the correct slot/ports to clear the E-W-MISMATCH alarm. Alternately, you can delete and recreate the span in CTC to change the West line and East line designations. The CTC method will clear the alarm, but may change the traditional East-West node connection pattern of the ring.


Note The E-W-MISMATCH alarm also appears during the initial set up of a ring with its East-West slot/ports configured correctly. In this instance, the alarm clears itself shortly after the ring setup is complete.



Note The lower-numbered slot on a node is traditionally labeled as the West slot and the higher numbered slot is labeled as the East slot. For example, Slot 6 is West and Slot 12 is East.


Procedure: Clear the E-W-MISMATCH Alarm with a Physical Switch


Step 1 Diagram the ring setup, including nodes and spans, on a piece of paper or white board.

Step 2 Display the CTC network view and label each of the nodes on the diagram with the same name that appears on the screen network map.

Step 3 Double-click each span to reveal the node name and slot/port for each end of the span.

Step 4 Label the span ends on the diagram with the same information. For example, with Node 1/Slot12/Port1 - Node2/Slot6/Port1, label the end of the span that connects Node 1 and Node 2 at the Node 1 end as Slot 12/Port 1. Label the Node 2 end of that same span Slot 6/ Port 1.

Step 5 Repeat Steps 3 and 4 for each span on your diagram.

Step 6 Label the highest-numbered slot at each node East and the lowest-numbered slot at each node West.

Step 7 Look at the diagram. You should see a clockwise pattern of West slots connecting to East slots for each span.

Step 8 If any span has an East-to-West or West-to-West connection, physically switch the fiber cable connectors from the card that does not fit the pattern to the card that will continue the pattern. This should clear the alarm.


Note The physical switch procedure is the recommend method of clearing this alarm. This method reestablishes the logical pattern of connection in the ring. However, you can also use CTC to recreate the span and identify the misconnected slot/ports as East and West. This is useful when the misconnected node is not geographically near the troubleshooter.



Warning On the OC192 LR/STM64 LH 1550 card, the laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).



Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls and adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.



Procedure: Clear the E-W-MISMATCH Alarm with CTC


Step 1 Log into the misconnected node. This is the node with both ring fiber cables misconnected. It is in the middle of the two nodes that have one of two ring fiber cables misconnected.

Step 2 Click the Provisioning > Ring tabs.

Step 3 From the row of information for the fiber span, write down the node ID, ring ID, and the slot and port in the East line list and West line list.

Step 4 Click the row from Step 3 to select it and click Delete.

Step 5 Click Create.

Step 6 Fill in the ring ID and node ID from the information collected in Step 3.

Step 7 Change the West line pull-down menu to the slot/port you recorded for the East line in Step 3.

Step 8 Change the East line pull-down menu to the slot/port you recorded for the West line in Step 3.

Step 9 Click OK.

Step 10 Click Yes at the Ring Map Change dialog box.

Step 11 Click Accept at the new ring map.


1.5.30 EXCCOL

Minor, Non-service affecting

The excess collisions on the LAN alarm indicates that too many collisions are occurring between data packets on the network management LAN, and communications between the ONS 15454 SDH unit and CTC may be affected. The network management LAN is the data network connecting the workstation running the CTC software to the TCC-I card. This problem is external to the ONS 15454 SDH.

Procedure: Clear the EXCCOL Alarm

Troubleshoot the network management LAN connected to the TCC-I card for excess collisions. You may need to contact the system administrator of the network management LAN to accomplish the following steps.


Step 1 Verify that the network device port connected to the TCC-I card has a flow rate set to 10 MB, half-duplex.

Step 2 Troubleshoot the network device connected to the TCC-I card and the network management LAN.

1.5.53 MFGMEM (Backplane or Fan)

Critical, Service-affecting

The manufacturing data memory (EPROM) failure alarm occurs if the ONS 15454 SDH cannot access the data in the EPROM. Either the memory module on the component failed or the TCC-I lost the ability to read that module. The EPROM stores manufacturing data that is needed for both compatibility and inventory issues. An inability to read a valid MAC address will disrupt IP connectivity and gray out the ONS 15454 SDH icon on the CTC network view.

Procedure: Clear the MFGMEM Alarm on the Backplane or Fan Tray


Step 1 Do a software-initiated system reset on the TCC-I with the "Initiate a Software Reset" procedure on page 4-4.

Step 2 If the alarm does not clear, follow the "Reset the TCC-I using a Card Pull" procedure on page 4-5.

Step 3 If the alarm does not clear, physically replace the standby TCCI card on the ONS 15454 SDH with a new TCC-I card:

a. Open the TCC-I card ejectors.

b. Slide the card out of the slot. This raises the IMPROPRMVL alarm which will clear when the upgrade is complete.

c. Open the ejectors on the TCC-I card.

d. Slide the TCC-I card into the slot along the guide rails.

e. Close the ejectors.


Note It takes approximately 20 minutes for the active TCC-I to transfer the system software to the newly installed TCC-I. Software transfer occurs in instances where different software versions exist on the two cards. During this operation, the LEDs on the TCC-I flash Fail and then the Active/Standby LED flashes. When the transfer completes, the TCC-I reboots and goes into Standby mode after approximately three minutes.


Step 4 Right-click the active TCC-I card to reveal a pull-down menu.

Step 5 Click Reset Card. Wait for the TCC-I to reboot. The ONS 15454 SDH switches the standby TCC-I card to active mode.

Step 6 Verify that the remaining TCC-I card is now in standby mode (the ACT/STBY LED changes to amber).

Step 7 Physically replace the remaining TCC-I card with the second TCC-I card:

a. Open the TCC-I card ejectors.

b. Slide the card out of the slot.

c. Open the ejectors on the TCC-I card.

d. Slide the TCC-I card into the slot along the guide rails.

e. Close the ejectors. The ONS 15454 SDH boots up the second TCC-I card. The second TCC-I must also copy the system software, which can take up to 20 minutes.

Step 8 If the MFGMEM alarm continues to report after replacing the TCC-I cards, the problem lies in the EPROM.

Step 9 If the MFGMEM is reported from the fan tray, replace the fan tray.

Step 10 If the MFGMEM is reported from backplane, or the alarm persists after the fan tray is replaced, login to http://www.cisco.com/tac for more information or login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country.

Step 2 Use a test set to determine that the external timing source is delivering SSM.


1.5.67 SWMTXMOD

Critical, Service-affecting

The switching matrix module failure alarm occurs on the XC10G card or an I/O card. If the alarm reports against an I/O card, it means that the logic component on the cross-connect card is out of frame (OOF) with the logic component on the reporting I/O card. All traffic on the reporting I/O card is lost. If the alarm reports against an XC10G card, it means that a logic component internal to the reporting XC10G card is out of frame with a second logic component on the same XC10G card. One or more I/O cards may lose traffic as a result of this failure.

Procedure: Clear the SWMTXMOD Alarm


Step 1 If the card reporting the alarm is the standby XC10G card, perform a software reset on the standby XC10G:

a. Display the node view.

b. Position the cursor over the slot reporting the alarm.

1.5.68 SYNCPRI

Minor, Non-service affecting

A loss of timing on primary reference alarm occurs when the ONS 15454 SDH loses the primary timing source (reference 1). The ONS 15454 SDH uses three ranking timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCPRI occurs, the ONS 15454 SDH should switch to its secondary timing source (reference 2). This switch also triggers the SWTOSEC alarm.

Procedure: Clear the SYNCPRI Condition


Step 1 From the node view, click the Provisioning > Timing tabs.

Step 2 Check the current configuration for the REF-1 of the NE reference.

Step 3 If the primary reference is a BITS input, verify the wiring connection from the ONS 15454 SDH backplane BITS clock pin fields to the timing source.

Step 4 Check that the BITS clock is operating properly.

Step 5 If the primary reference clock is an incoming port on the ONS 15454 SDH, complete the "LOS (E-N)" procedure.


1.5.69 SYNCSEC

Minor, Non-service affecting

A loss of timing on secondary reference alarm occurs when the ONS 15454 SDH loses the secondary timing source (reference 2). The ONS 15454 SDH uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCSEC occurs, the ONS 15454 SDH should switch to the third timing source (reference 3) to obtain valid timing for the ONS 15454 SDH. This switch also triggers the SWTOTHIRD alarm.

Procedure: Clear the SYNCSEC Alarm


Step 1 From the node view, click the Provisioning > Timing tabs.

Step 2 Check the current configuration of the REF-2 for the NE Reference.

Step 3 If the secondary reference is a BITS input, verify the wiring connection from the ONS 15454 SDH backplane BITS clock pin fields to the timing source.

Step 4 Check that the BITS clock is operating properly.

Step 5 If the secondary timing source is an incoming port on the ONS 15454 SDH, complete the "LOS (E-N)" procedure.


1.5.70 SYNCTHIRD

Minor, Non-service affecting

A loss of timing on the third reference alarm occurs when the ONS 15454 SDH loses the third timing source (reference 3). The ONS 15454 SDH uses three ranking timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCTHIRD occurs and the ONS 15454 SDH uses an internal reference for source three, then the TCC-I card may have failed. The ONS 15454 SDH often reports either FRNGSYNC or HLDOVERSYNC alarms after a SYNCTHIRD alarm.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the SYNCTHIRD Alarm


Step 1 From node view, click the Provisioning > Timing tabs.

Step 2 Check the current configuration of the REF-3 for the NE Reference.

Step 3 If the third timing source is a BITS input, verify the wiring connection from the ONS 15454 SDH backplane BITS clock pin fields to the timing source.

Step 4 Check that the BITS clock is operating properly.

Step 5 If the third timing source is an incoming port on the ONS 15454 SDH, complete the "LOS (E-N)" procedure.

Step 6 If the third timing source uses the internal ONS 15454 SDH timing, perform a software reset on the TCC-I card:

a. Display the CTC node view.

b. Position the cursor over the slot reporting the alarm.

c. Right-click and choose RESET CARD.

Step 7 If this fails to clear the alarm, physically reseat the TCC-I card.

Step 8 If the reset fails to clear the alarm, replace the TCC-I card.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.



1.5.71 SYSBOOT

Major, Service-affecting

The system reboot alarm indicates that new software is booting on the TCC-I card. This is an informational alarm. No action is required. The alarm clears when all cards finish rebooting the new software. The reboot takes up to 30 minutes.

1.5.72 TPTFAIL

Major, Service affecting

The transport layer failure alarm indicates a break in the end-to-end Ethernet link integrity feature of the G1000-4 cards. This alarm indicates a far-end condition and not a problem with the port reporting TPTFAIL.

This alarm indicates a problem on either the SDH path or the remote Ethernet port, which prevents the complete end-to-end Ethernet path from working. If there is any SDH path alarm on the SDH path used by the Ethernet port, the affected port raises a TPTFAIL alarm. If the far-end G1000-4 Ethernet port is administratively disabled or it is seeing a CARLOSS condition, it will set the C2 byte in the SDH path overhead to indicate a payload defect condition (PDI-P). This will cause a TPTFAIL to be reported against this near-end port.

Another important point regarding a TPTFAIL condition is that the near-end port is automatically disabled (transmit laser turned off) when this condition occurs. This could cause the external Ethernet device attached at the near end to detect a downed link, and turn off its transmitter. In turn, this would cause a CARLOSS condition on this port. In all cases the real problem is either in the SDH path being used by this G1000-4 port or the far-end G1000-4 port to which it is mapped.

Procedure: Clear the TPTFAIL Alarm


Step 1 An occurrence of TPTFAIL on a G1000-4 port indicates either a problem with the SDH path that this port is using or with the far-end G1000-4 port that is mapped to this port. Look up and troubleshoot any alarms being reported by the STM-N card utilized by the Ethernet circuit of the G1000-4.

Step 2 If no alarms are reported by the STM-N card, the problem may be on the far- end G1000-4 port that the port reporting TPTFAIL is mapped to. Lookup and troubleshoot any alarms, such as CARLOSS, reported against the far-end port or card.


1.5.73 TRMT

Major, Service-affecting

A facility termination equipment failure alarm occurs when there is a transmit failure on the E1-N-14 card because of an internal hardware failure. The card must be replaced.


Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Procedure: Clear the TRMT Alarm on the E1-N-14 Card


Step 1 Replace the E1-N-14 card reporting the failure.


Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Consult Chapter 4, "Maintenance," for information.


Note When replacing a card with an identical type of card, you do not need to change the CTC database.


Step 2 Login to http://www.cisco.com/tac to obtain information about handling the failed card or for more information, login to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center toll-free numbers for your country.


1.5.74 TRMT-MISS

Major, Service-affecting

A facility termination equipment transmitter missing alarm occurs when the facility termination equipment detects an incorrect amount of impedance on its backplane connector. This means the transmit fiber cable is missing on the E1 port, or the backplane does not match the inserted card. For example, the alarm is raised if an SMB connector or a BNC connector is connected to an E1-N-14 card instead of an E3-12 card.


Note E-1s are four-wire circuits and need a positive and negative connection for both transmit and receive.


Procedure: Clear the TRMT-MISS Alarm


Step 1 Check that the device attached to the E1 port is operational.

Step 2 Verify that the cabling is securely connected.

Step 3 Verify that the pinouts are correct.

Step 4 If Steps 1 - 3 do not clear the alarm, replace the transmit fiber cable.
