Step 6
Tighten the captive screw on the lower left side of the network module.
Step 7
Do one of the following:
a) Power up the chassis so that the new network module is recognized (if the new network module does
not
support hot
swapping).
b) Bring the new network module online using the appropriate CLI command (if the new network module
supports
hot
swapping). The saved network module configuration is automatically reapplied when the network module is back
online.
If you install a network module that is a different PID than the original network module, the saved
configuration is deleted and the default configuration is applied. You must enter the
acknowledge
command
to confirm the network module PID change.
Note
What to do next
Follow the procedures in the
to connect to the network module and make sure
that it has been discovered correctly by the Firepower 4100.
Remove and Replace the Fan Module
You can remove and replace fan modules while the system is running. The air flow moves from front to back.
If you remove a fan or a fan fails, the other fans operate at full speed, which can be noisy.
The system supports operation with a single fan failure (N+1 fan redundancy), but do not run the system for
an extended amount of time without all fan modules installed. Keep removal and replacement time at three
minutes. Remove and replace one fan module at a time.
