Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite



Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.



Caution Removing any active card from the ONS 15454 can result in traffic interruption. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If the active card needs to be replaced, follow the steps below to switch the XC/XCVT/XC10G card to standby prior to removing the card from the node.


Note An improper removal (IMPROPRMVL) alarm is raised whenever a card pull is performed, unless the card is deleted in CTC first. The alarm will clear after the card replacement is complete.



Note In a UPSR, pulling the active cross-connect card (XC/XCVT/XC10G) without a lockout will cause UPSR circuits to switch.



Step 1 Log into the node where you will perform the cross-connect card (XC/XCVT/XC10G) replacement:

a. From your PC, start Netscape or Internet Explorer.

b. In the Netscape or Internet Explorer Web address (URL) field, enter the ONS 15454 IP address. For initial setup, this is the default address, 192.1.0.2. Press Enter.

A Java Console window displays the CTC file download status. The web browser displays information about your Java and system environments.

c. In the Login dialog box, type your name and password. (Both are case sensitive.)

d. Each time you log into an ONS 15454, you can make selections on the following login options:

Node Name—Displays the IP address entered in the web browser and a pull-down menu of previously-entered ONS 15454 IP addresses. You can select any ONS 15454 on the list for the login, or you can enter the IP address (or node name) of any new node where you want to log in.

Additional Nodes—Displays a list of login node groups that were created. (To create a login node group or add additional groups, see the Cisco  ONS 15454 Procedure Guide.)


Note Topology hosts that were created in previous ONS 15454 releases by modifying the ctc.ini file are displayed as a "Topology Host" group under Additional Nodes.


Exclude Dynamically Discovered Nodes—Check this box to view only the ONS 15454 (and login node group members, if any) entered in the Node Name field. Nodes linked to the Node Name ONS 15454 through the DCC are not displayed. Using this option can decrease the CTC startup time in networks with many DCC-connected nodes.

e. Click Login.

Step 2 Ensure the working span is active on both local and remote nodes:

a. In node (default login) view, click the Maintenance > BLSR tabs.

b. Locate the applicable span.

In the West Line and East Line columns, the working/active span is identified by (Work/Act).

Step 3 Ensure the working span is carrying error-free traffic (no SD or SF alarms present). Display the network view and click the Alarms tab to display alarms.

Step 4 Lock out the protection span according to the specific protection scheme:

a. Lock out the protection span in a BLSR protection scheme:

In node (default login) view, click the Maintenance > BLSR tabs. Locate the applicable span. In the West Line and East Line columns, the working/active span is identified by (Work/Act). Place a lockout on the East and West cards of the nodes adjacent to the XC switch node. For example, to switch the cross-connect card (XC) on Node B, place a lockout on the West card of Node A and on the East card of Node C, no lockout is necessary on Node B.

<------East [Node A] West------East [Node B] West------East [Node C] West------>

Before the lockout is set, verify that the BLSR is not switched. If a lockout is set while the BLSR is switched, traffic can be lost. Choose the correct row for the span and then under the West Switch column, choose LOCOUT SPAN from the list box.

b. Lock out the protection span in a 1+1 protection scheme:

In node (default login) view, click the Maintenance > Protection tabs.

Choose the affected 1+1 protection group from the Protection Groups window.

In the Selected Group window, the working and protect spans appear. Choose the protect/standby card and click Lock Out.

Click Yes on the confirmation dialog box.


Note A cross-connect card (XC/XCVT/XC10G) reset can cause a linear 1+1 OC-N protection switch or a BLSR protection switch.


c. Lock out the protection span in a UPSR protection scheme:

Click the Circuits tab.

Locate the span row.

Under the Switch State column, click the Switch all UPSR- circuits away menu.

Choose Clear and click Apply.

Click Yes at the Confirm UPSR Switch Are You Sure? dialog box.

Click OK at the confirmation dialog box.


Caution The FORCE command overrides normal protective switching mechanisms. Applying this command incorrectly can cause traffic outages.

Step 5 When the protection span has been locked out, determine the active cross-connect card (XC/XCVT/XC10G). The ACT/STBY LED of the active card is green. The ACT/STBY LED of the standby card is amber.


Note You can also place the cursor over the card graphic to display a pop-up identifying the card as active or standby.


Step 6 Switch the active cross-connect card (XC/XCVT/XC10G) to standby:

a. In the node (default login) view, click the Maintenance > XC Cards tabs.

b. Under Cross Connect Cards, choose Switch.

c. Click Yes on the Confirm Switch dialog box.


Note After the active XC/XCVT/XC10G goes into standby, the original standby slot becomes active. This causes the ACT/STBY LED to become green on the former standby card.


Step 7 Physically remove the new standby cross-connect card (XC/XCVT/XC10G) from the ONS 15454.

Step 8 Insert the replacement cross-connect card (XC/XCVT/XC10G) into the empty slot.

The replacement card boots up and becomes ready for service after approximately one minute.

Step 9 Release the protection lockout(s) applied in Step 4:

a. Log into the node where you will clear the lockout.

b. Click the Maintenance > Protection tabs.

c. Under Protection Groups, click the protection group that contains the card you want to clear.

d. Under Selected Group, click the card you want to clear.

e. Click Clear.

f. Click Yes on the confirmation dialog box.

The lockout is cleared.

Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite



Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.



Note Although the filter will work if it is installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter.



Step 1 To replace the reusable air filter, complete the "3.3.1Inspect, Clean, and Replace the Reusable Air Filter" task.

Step 2 To replace the disposable air filter, complete the "3.3.2Inspect and Replace the Disposable Air Filter" task.


3.3.1 Inspect, Clean, and Replace the Reusable Air Filter

Purpose

This task ensures that the air filter is free from dirt and dust, which allows optimum air flow and prevents dirt and dust from entering the shelf.

Tools/Equipment

Vacuum or detergent and water faucet, spare filter, pinned hex key

Prerequisite Procedures

None

Required/As Needed

Inspection required every 30 days. Clean as needed.

Onsite/Remote

Onsite



Step 1 Verify that you are replacing a reusable air filter. The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later versions of the ONS 15454 use a reusable air filter.

Step 2 If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful not to dislodge any dust that may have collected on the filter and proceed to Step 3. Figure 3-1 illustrates a reusable fan-tray air filter in an external filter bracket. If the filter is installed beneath the fan tray and not in the external filter brackets:

a. Open the front door of the shelf assembly.

Open the front door lock.

The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.

Press the door button to release the latch.

Swing the door open.

b. Remove the front door (optional). If you do not want to remove the door, proceed to Step 3:

Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.

Secure the dangling end of the ground strap to the door or chassis with tape.

Figure 3-1 A reusable fan-tray air filter in an external filter bracket (front door removed)

Step 3 Push the outer side of the handles on the fan-tray assembly to expose the handles.

Step 4 Pull the handles and slide the fan-tray assembly one inch out of the shelf assembly and wait until the fans stop.

Step 5 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.

Step 6 Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that may have collected on the filter.

Step 7 Visually inspect the air filter material for dirt and dust.

Step 8 If the reusable air filter has a concentration of dirt and dust, either vacuum or wash the air filter. Prior to washing the air filter, replace the dirty air filter with a clean air filter and also reinsert the fan-tray assembly. Wash the dirty air filter under a faucet with a light detergent.

Spare ONS 15454 filters should be kept in stock for this purpose.


Note Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.


Step 9 If you washed the filter, allow it to completely air dry for at least eight hours.


Warning Do not put a damp filter back in the ONS 15454.

a. If the air filter is installed in the external filter brackets, slide the air filter all the way to the back of the brackets to complete the procedure.

b. If the filter is installed beneath the fan-tray assembly, remove the fan-tray assembly and slide the air filter into the recessed compartment at the bottom of the shelf assembly. Put the front edge of the air filter flush against the front edge of the recessed compartment. Push the fan tray back into the shelf assembly.


Caution If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and readjust the position of the reusable filter until the fan tray fits correctly.

Note On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly inserted.


Step 10 To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray assembly is activated and displays node information.

Step 11 Rotate the retractable handles back into their compartments.

Step 12 If you replace the door, also reattach the ground strap.

Step 13 Close and lock the door.


3.3.2 Inspect and Replace the Disposable Air Filter

Caution Do not use a 2A AIP with a 5A fan-tray assembly; doing so will cause a blown fuse on the AIP.


Caution There is a risk of Ethernet traffic disruptions. Contact the Cisco Technical Assistance Center (TAC) at 877-323-7368 when prompted to do so in the procedure.


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


Note Perform this procedure in a maintenance window. Resetting the active TCC+ can cause a service disruption of less then 50 ms to OC-N or DS-N traffic. Resetting the active TCC+ will cause a service disruption of 3-5 minutes on all Ethernet traffic due to Spanning Tree Reconvergence.



Step 1 Ensure that all nodes in the affected network are running the same software version before replacing the AIP and repairing circuits:

a. Log into CTC. See Step 1 in the "Switch Traffic and Replace an In-Service Cross-Connect Card" procedure for instructions.

b. In network view, click the Maintenance > Software tabs. The working software version for each node is listed in the Working Version column.

c. If you need to upgrade the software on a node, refer to the Cisco ONS 15454 Software Upgrade Guide for software upgrade procedures. No hardware should be changed or circuit repair performed until after the software upgrade is complete. If you do not need to upgrade software or have completed the software upgrade, proceed to Step 2.

Step 2 Record the MAC address of the old AIP:

a. Log into the node where you will replace the AIP. For login procedures, see the Cisco ONS 15454 Procedure Guide.

b. In node (default login) view, click the Provisioning > Network tabs.

c. Record the MAC address shown in the General tab in Figure 3-5.
