OC48 LR/STM16 LH AS 1550 Card
The OC48 LR/STM16 LH AS 1550 card provides one long-range, ITU-T G.707, ITU-T G.957-compliant, SDH STM-16 port per card. The interface operates at 2.488 GBits/s (Gbps) over a single-mode fiber span. The card supports concatenated or non-concatenated payloads at STM-1, STM-4, or STM-16 signal levels on a per VC-4 basis. Figure 1 shows the OC48 LR/STM16 LH AS 1550 faceplate and Figure 2 shows a block diagram of the card.

You can install OC48 LR/STM16 LH AS 1550 cards in any multispeed or high-speed slot on the ONS 15454 SDH. You can provision this card as part of a MSSPRing or SNCP. In an ADM/TM configuration, you can provision the card as either an access tributary or a transport span interface.
The OC48 LR/STM16 LH AS 1550 port features a 1550 nm laser and contains a transmit and receive connector (labeled) on the card faceplate. The card uses SC connectors, and it supports 1+1 unidirectional protection and provisionable bidirectional and unidirectional switching.
The OC48 LR/STM16 LH AS 1550 detects LOS, LOF, LOP, MS-AIS, and MS-FERF conditions. Refer to Chapter 10, "Alarm Monitoring and Management," of the "Cisco ONS 15454 SDH Installation and Operations Guide, R3.3" for a description of these conditions. The card also counts section and line BIT errors.
OC48 LR/STM16 LH AS 1550 Card-Level Indicators
The OC48 LR/STM16 LH AS 1550 card has three card-level LED indicators.

Card-Level LEDs
|
Description
|
Red FAIL LED |
The red FAIL LED indicates the card's processor is not ready. This LED is lit during Reset. The FAIL LED flashes during the boot process. Replace the card if the red FAIL LED persists. |
Green ACT LED |
The green ACT LED indicates that the OC48 LR/STM16 LH AS 1550 card is carrying traffic or is traffic-ready. |
Yellow SF LED |
The yellow SF LED indicates a signal failure or condition such as LOS, LOF or high BERs on one or more of the card's ports. The Yellow SF LED also illuminates when the transmit and receive fibers are incorrectly connected. When the fibers are properly connected and the link is working, the light turns off. |
OC48 LR/STM16 LH AS 1550 Port-Level Indicators
You can find the status of the OC48 LR/STM16 LH AS 1550 card ports using the LCD screen on the ONS 15454 SDH fan tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot. Refer to Chapter 10, "Alarm Monitoring and Management," of the "Cisco ONS 15454 SDH Installation and Operations Guide, R3.3" for a complete description of the alarm messages.

Installation Procedures
Use this section if you are installing or removing the OC48 LR/STM16 LH AS 1550 card for the first time. After you become familiar with ONS 15454 SDH card installation and boot up, use this section as a reference.
Caution
Always use the supplied electrostatic discharge (ESD) wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf assembly and ensure the shelf assembly is properly grounded.
Caution
Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.
Step 1 Open the card ejectors.
Step 2 Carefully insert the card into the guide rails of the desired slot (Figure 3).
Step 3 Push the card into the connector on the back plane by closing the ejectors.
Figure 3 Installing cards in an ONS 15454 SDH
Card Turn Up
Follow the steps in this section to verify card turn up. If one or more of the Cisco Transport Controller (CTC) software screen conditions according to "Verify Successful Turn Up of the OC48 LR/STM16 LH AS 1550 Card" section are not met, re-install the card. Replace the unit if the faulty state persists.
Verify Successful Turn Up of the OC48 LR/STM16 LH AS 1550 Card
Step 1 Verify that power is applied to the shelf assembly.
Step 2 Verify that the OC48 LR/STM16 LH AS 1550 card has been installed in the correct slot.
Step 3 Verify that the card appears in the correct slot on the CTC software screen.
Step 4 Verify that the card is white on the CTC software screen.
Step 5 Verify that the card is shown in Inventory on the CTC software screen.
Removal Procedures
Use this section if you are installing or removing the OC48 LR/STM16 LH AS 1550 card for the first time. After you become familiar with ONS 15454 SDH card installation and boot up, use this section as a reference.
Caution
Always use the supplied electrostatic discharge (ESD) wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf assembly and ensure the shelf assembly is properly grounded.
Caution
Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.
Note Traffic can be interrupted if you pull an active card from the ONS 15454 SDH. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If an active card needs to be replaced, follow the procedure to switch the electrical card to standby mode before you pull the card from the node.
Reset an STM-N Card
Note An STM-N reset can cause a linear 1+1 STM-N protection switch or an MSSPRing protection switch.
Note Traffic can be interrupted if you pull an active card from the ONS 15454 SDH. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If an active card needs to be replaced, follow the procedure to switch the STM-N card to standby mode before you pull the card from the node.

Warning Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.

Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view 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.
|
The STM-N card should be replaced if a red FAIL LED appears.
Take these precautions before initiating an STM-N card reset to avoid causing a linear 1+1 or MSSPRing protection switch:
Step 1 Ensure that the working (active) span is active on the local and remote nodes.
Step 2 Ensure that the working (active) span is carrying error-free traffic without FAIL alarms or SF alarms.
Step 3 Perform a lockout on the protection span in the CTC software before initiating an STM-N card reset. In an MSSPRing, place a lockout on the East and West node cards adjacent to the XC10-G switch node. For example, if you are switching the XC10-G on Node B, place a lockout on the Node A West card and on the Node C East card. You do not need to place lockouts on Node B. Before settingthe lockout, verify that the MSSPRing is not switched. Traffic can be lost if the MSSPRing is switched when the lockout is set.
<------East [Node A] West------East [Node B] West------East [Node C] West------>
In a 1+1 protection scheme, place a lockout on the protect card and verify that traffic is traveling over the working span before setting the lockout.
Replace an In-Service STM-N Card
Caution
Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.
Step 1 In the CTC software, determine which STM-N card is active.
Note You can determine whether the card is in active mode or standby mode by viewing it in the CTC software and positioning the cursor over the card graphic to display the status.
Step 2 Switch the active STM-N card to standby:
a. In the node view, select the Maintenance > STM Cards tabs.
b. From the Cross Connect Cards menu, choose Switch.
c. Click Yes on the Confirm Switch dialog box.
Note After the working STM-N card goes into protection, the protection slot becomes working. This causes the former working card ACT LED to switch off.
Step 3 Pull the protection STM-N card from the ONS 15454 SDH.
Step 4 Insert the replacement STM-N card into the empty slot. The replacement card boots up and becomes ready for service after approximately one minute. After this procedure the card is ready for protection function.
