10/100/1000Base-T Twisted-Pair Ports

A twisted-pair cable port is shown in Figure 7.

Figure 7. Twisted-Pair Cable Port

See Figure 19 on page 84 for the pin layout to a port and RJ-45 connector.

Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set

manually using the management software or automatically with

Autonegotiation (IEEE 802.3u), the default setting.

Note

The ports must be set to Autonegotiation to function at 1000 Mbps.

They are not compatible with devices that are not IEEE 802.3u

compliant.

Duplex Mode The twisted-pair ports can operate in either half- or full-duplex mode. The

duplex modes, like port speeds, may be set manually using the

management software or automatically with Autonegotiation (IEEE

802.3u), the default setting.

The speed and duplex mode settings of a port may be set independently

of each other. For example, a port may be configured such that its speed

is set manually while its duplex mode is established through

Autonegotiation.
