100-Gb Network Module (Double Wide)
The following figure shows the front panel of the 100-Gb network module (FPR9K-DNM-2X100G). The
FPR9K-DNM-2X100G is a double-wide module that does not support hot swapping. The two ports are
numbered left to right.
Make sure you have the correct firmware package and software version installed to support this network
module. For instructions on how to verify your firmware package version and to upgrade the firmware if
necessary, see the Cisco Firepower 4100/9300 FXOS Firmware Upgrade Guide. See Cisco Firepower 4100/9300
FXOS Compatibility for the software compatibility matrix.

Hardware Bypass Network Modules
Hardware bypass (also known as fail-to-wire) is a physical layer (Layer 1) bypass that allows paired interfaces
to go into bypass mode so that the hardware forwards packets between these port pairs without software
intervention. Hardware bypass provides network connectivity when there are software or hardware failures.
Hardware bypass is useful on ports where the Firepower security appliance is only monitoring or logging
traffic. The hardware bypass network modules have an optical switch that is capable of connecting the two
ports when needed. The hardware bypass network modules have built-in SFPs.
Hardware bypass is supported only on a fixed set of ports. You can pair Port 1 with Port 2, Port 3 with Port
4, but you cannot pair Port 1 with Port 4 for example.
