Cisco ASA 5508-X

You can configure any of the Gigabit Ethernet interfaces to be a management-only interface using the
management-only command. However, you cannot disable management-only mode on the Management 1/1 interface.
The following figure shows how to connect the network cables.

b)
(Optional) Console port – For use with the CLI. Connect a computer or terminal server using a serial console cable
to either the RJ-45 or Mini USB Type B port.
Only one console port can be active at a time. When a cable is plugged into the USB console port, the RJ-45 port
becomes inactive. Conversely, when the USB cable is removed from the Mini USB Type B port, the RJ-45 port
becomes active. See Connect to a Console Terminal or PC, on page 24 for specific instructions for connecting the
console port.
c)
Gigabit Ethernet ports – For the network interfaces; use standard RJ-45 Ethernet cables.
You can use any available Gigabit Ethernet port on the ASA 5508-X or ASA 5516-X as a failover link. The failover
link interface is not configured as a normal networking interface; it should only be used for the failover link. You
can connect the failover link by using a dedicated switch with no hosts or routers on the link.
