Connecting the 10/100Base-T Ethernet port to an Ethernet switch or hub
The 10/100Base-T Ethernet port (see figure 12 on page 31) is designed to connect to an Ethernet switch or
hub. Connect a straight-through CAT-5 cable (one wired as shown in figure 13) between the RAS and the
hub/switch.

Connecting the 10/100Base-T Ethernet port to an Ethernet-capable workstation
The 10/100Base-T Ethernet port can connect to a single Ethernet-capable workstation by means of a cross-
over cable. Refer to figure 14 to assemble a cross-connect cable that will connect between the NIC Ethernet
port in the workstation and the RAS 10/100Base-T Ethernet port.
