System Maintenance
Equipment Replacement
Warning: Replace only one plug-in at a time, if power is applied to blade, to maintain proper air flow and
prevent damage due to potential overheating. The first PIU must be replaced before proceeding to replace
the next PIU.
Attention: Do not replace the PIU if replacing a contained SFP, SFP+, or CFP4 module can clear the
alarm.

Step 2
Are any alarms and standing conditions currently being reported?
If YES:
Clear all active alarms and standing conditions, as necessary, before continuing this procedure. After these

Step 3
Is it possible that replacing a single pluggable optics module clears the current alarms?

only if replacing the modules does not clear the problem.
If NO:
Continue with next step.
Step 4
Inspect the fiber connections to the PIU. Verify that each fiber is clearly marked or labeled to identify the correct
connection location.
Step 5
Is each fiber clearly marked to show its corresponding connector?
