Replace an OC-192 Card
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 Card removal raises an improper removal (IMPROPRMVL) alarm, but this clears after the card
replacement is completed.
Step 1 Log into the node where you will replace the OC-192 card. If necessary, refer to the
Cisco ONS 15600 Procedure Guide for a login procedure.
Step 2 Ensure that the card you are replacing does not carry traffic in a 1+1 group:
a. In the node view, click the Maintenance > Protection tabs.
b. Choose the first group listed under Protection Groups.
c. Verify that the slot number for the card you are replacing does not appear in the Selected Groups
list. For example, if you are replacing the OC-192 card in slot 3, make sure that Selected Groups
does not contain any entries that start with s3, regardless of the port.
d. Repeat Steps b and c for each protection group.
e. If any of the groups contain a port on the card you want to replace, perform the “Force-Switch 1+1
Ports” task on page 10.
