See “Terminal and Modem Cables” on page 28 for more information on

connection options for the RS-232 console ports.

RJ-45 Ports

For 10BASE-T/100BASE-TX connections, a twisted pair cable must be used.

Each pair is identified by two different colours. For example, one wire might be

red, and the other red with a white stripe. An RJ-45 connector must be fitted to

both ends of the cable. Figure 20 illustrates the pin layout for RJ-45 connectors.

Caution Do not plug a phone jack into an RJ-45 switch port because you could

damage the switch. Use only twisted pair cables with RJ-45 connectors.

Figure 20: RJ-45 Pin layout

With 10BASE-T/100BASE-TX cables, pins 1 and 2 are used for transmitting

data, while pins 3 and 6 are used for receiving data. Table 9 on page 19 lists the

RJ-45 Pin assignments.
