    M40e Fast Ethernet PIC 48-port Cable Pinouts

    The Fast Ethernet 48-port PIC has four VHDCI connector ports on its faceplate (see Figure 1), each of which accepts one of the four RJ-21 cables supplied with the PIC (see Figure 2). Each VHDCI connector port supports 12 Ethernet ports.

    Table 1 describes the RJ-21 cable pinouts.

    Note: RJ-21 pin numbers 25 and 50 do not appear in the table because they are ground connectors.
