Catalyst 2970 Switch Hardware Installation Guide

OL-6422-01

Step 1

When connecting to servers, workstations, and routers, insert a four twisted-pair,
straight-through cable in the RJ-45 connector. When connecting to switches or
repeaters, insert a four twisted-pair, crossover cable.

Note

When connecting to a 1000BASE-T device, be sure to use a four twisted-pair,
Category 5 cable.

Note

You can use the

mdix auto

interface configuration command in the CLI to enable

the automatic medium-dependent interface crossover (Auto-MDIX) feature.
When the Auto-MDIX feature is enabled, the switch detects the required cable
type for copper Ethernet connections and configures the interfaces accordingly.
Therefore, you can use either a crossover or a straight-through cable for
connections to a copper 10/100/1000 or 1000BASE-T SFP module port on the
switch, regardless of the type of device on the other end of the connection.

The Auto-MDIX feature is enabled by default on switches running Cisco IOS
Release 12.2(18)SE or later. For releases between Cisco IOS
Release 12.1(14)EA1 and 12.2(18)SE, the Auto-MDIX feature is disabled by
default. For configuration information for this feature, see the switch software
configuration guide or the switch command reference
