Verifying the Replaced SIBs

1. Bring the SIB online by using one of the following methods:
• Press and hold the ONLINE/OFFLINE button on the SIB faceplate. The green OK LED on the
faceplate begins to blink. Hold the button down until the LED blinks.
• Issue the following CLI command on the PTX5000:
user@host> request chassis sib online slot
2. To verify that all the new SIBs are installed, use the show chassis hardware command. The new SIBs ID
should be displayed in the command output (see
page 7).
To verify the status of the SIBs:
• Issue the show chassis fabric errors command at the [edit] hierarchy level to verify the link status
for each SIB.
Also use the show chassis fabric sibs command to check the link status for each SIB.
• Issue the show chassis fabric fpcs command at the [edit] hierarchy level to check whether any fabric
error is logged.
• Use the show chassis fabric topology to check the link status of all the SIBs and Packet Forwarding
Engines.
3. If there are any errors in the replaced SIB, debug the errors. See
