Twisted Pair Ports

Table 5 lists the cable specifications for the twisted pair ports.

The twisted pair ports feature standard RJ-45 8-pin connectors. For the

port pinouts, refer to “Twisted Pair Port Pinouts” on page 174.

The ports are IEEE 802.3u. compliant and use Auto-Negotiation to

automatically set their speeds and duplex modes. To adjust the ports

manually, you have to use the optional management module.

The twisted pair ports also have auto-MDI/MDI-X, which enables them to

automatically adjust their wiring configuration to MDI or MDI-X, depending

on the wiring configuration of the end nodes. This allows you to use a

straight-through twisted pair cable regardless of the wiring configuration of

the ports on the network devices.

The auto-MDI/MDI-X feature is only available when the twisted pair ports

are using Auto-Negotiation, the default setting. If you disable Auto-

Negotiation on a port and set the speed and duplex mode manually, this

feature is also disabled and the port defaults to the MDI-X setting.
