Chapter 2: Installation

Planning the Installation

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.
