The FM-24Ti module has 24 10/100 Mbps autonegotiation Ethernet ports, using standard RJ-21 
connectors. The FM-24Ti module supports 10BASE-T and 100BASE-TX.

Table 47 describes the cable specifications for the Alpine FM-24Ti module. Appropriate cables are 
available from your local supplier.

To access the ports, use a 180-degree male RJ-21 connector with a shielded PVC trunk cable and secure 
to a maximum of 4 in-lbs of torque. You can access the ports in one of the following ways:

Through a patch panel by terminating the cable and shield with an RJ-21 connector.

Directly by using a cable that is terminated with 12 RJ-45 connectors.

The RJ-21 connector is shown in Figure 80.
