Hardware Bypass Network Modules

Note You can fit four copper SFPs in either the top row of ports or the bottom row of ports. Both rows cannot be
populated at the same time, because of the port row spacing. For a list of copper SFPS.

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.
