Chapter 3 Installing the Cisco ASA 5505

Connecting the Interface Cables

a.Ethernet ports

Step 1 Connect Port 0, the outside Ethernet port, to the public network, that is, the Internet:

Note By default, switch port 0/0 is the outside port. If needed you can change the inside and outside ports assignments later.

Step 2 Connect your network devices with an Ethernet cable to one of the inside ports (numbered 1 through 7).

If you are connecting any PoE devices, connect them to one of the switch ports that support PoE (ports numbered 6 and 7).

Step 3 Check the LINK LED to verify that the network devices have basic connectivity to the Cisco ASA 5505 on one of the inside ports (numbered 0 through 7). When connectivity is established, the LINK LED on the front panel of the Cisco ASA 5505 lights up solid green.
