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.
