Install, Remove, and Replace the Network Module
You can remove and replace the network modules (NM-2 and NM-3) in the Secure Firewall 4200. Although
the hardware supports removing and replacing the network module while the system is running, the software
does not currently support hot swapping. You must power down the chassis or disable the network slot to
remove and replace network modules.
See the configuration guide for your operating system for the procedure for managing network modules.
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.
