This procedure describes how to install a network module into an empty slot that has never contained a network
module, and how to remove an installed network module and replace it with another network module.
Step 1 To install a new network module for the first time into an empty slot, do the following:
a) Power down the chassis by moving the power switch to the OFF position.
See Rear Panel, on page 10 for more information about the power switch.
b) Follow Steps 4 through 7 to install the new network module.
c) Power on the chassis by moving the power switch to the ON position.
The state for the new network module is OIR Failed.
d) To change the status of the network module to Online, reboot the chassis. See the "Rebooting the Firepower 4100/9300
Chassis" topic in the System Administration chapter in the FXOS Configuration Guide for your software version.
Step 2 To remove and replace an existing network module, do one of the following:
a) Save your configuration.
b) Power down the chassis by moving the power switch to the OFF position (if removing a network module that does
not support hot swapping).
See Rear Panel, on page 10 for more information about the power switch.
c) Bring the network module offline using the appropriate CLI command (if removing a network module that supports
hot swapping). All network module configuration is saved. See the “Taking a Network Module Offline or Online”
topic in the Security Module/Engine Management chapter in the FXOS Configuration Guide for your software version.
d) Continue with Step 3.
Step 3 To remove a network module from the chassis, loosen the captive screw on the lower left side of the network module
and pull out the handle that is connected to the screw. This mechanically ejects the network module from the slot.
