10/100Base-
TX Twisted
Pair Cabling
Table 7 lists the cable requirements for the 10/100Base-TX
twisted pair ports. For port pinouts, refer to “10/100Base-TX
Port Pinouts” on page 62.
Note
The default setting for a twisted pair port is Auto-
Negotiation and auto-MDI/MDI-X. In the default
setting, a port’s speed, duplex mode, and MDI/MDI-X
setting are set automatically. Disabling Auto-
Negotiation and manually configuring a port requires
the optional management module for the chassis.
