Step 3
Install the SFP/SFP+ transceivers.
Install SFP/SFP+/ transceivers in the Ethernet network interfaces in the fixed ports or in the network modules you have
installed taking care not to touch the contacts in the rear.
Flip the SFP+ over to connect in the upper ports. The SFP+ connects in the normal way in the lower ports. The sockets
on the upper row face up and the sockets on the lower row face down.
Do not force an SFP transceiver into a socket. This can jam the transceiver and can cause permanent damage
Warning
to the transceiver, the chassis, or both.
Caution Although non-Cisco SFPs are allowed, we do not recommend using them because they have not been tested
and validated by Cisco. Cisco TAC may refuse support for any interoperability problems that result from
using an untested third-party SFP transceiver. See
of supported Cisco transceivers.
The Ethernet 1/1 (WAN) port is
configured by default for internet
access. Connect your DHCP enabled
cable modem (internet) to this port.
The Ethernet 1/2 (inside) port is
configured by default for inside
access. Firepower 2100 bootstrapping
is only supported on Ethernet 1/2 or
on Management 0.
