Connecting to the Switch Ports

This section describes how to connect to the fixed switch ports and to the
10-Gigabit Ethernet module slots.

Connecting to 10/100/1000 Ports

The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet
pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX
and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP
cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.

The autonegotiation feature is enabled by default on the switch. At this setting,
the switch ports configure themselves to operate at the speed of attached devices.
If the attached device does not support autonegotiation, you can explicitly set the
switch port speed and the duplex parameters. To maximize performance, either let
the ports autonegotiate both speed and duplex, or set the port speed and duplex
parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover
(auto-MDIX) feature is enabled by default. With auto-MDIX enabled, the switch
detects the required cable type for copper Ethernet connections and configures the
interface accordingly. Therefore, you can use either a crossover or a
straight-through cable for connections to a switch 10/100/1000 Ethernet port,
regardless of the type of device on the other end of the connection.

See the switch software configuration guide or the switch command reference on
Cisco.com for more information about enabling or disabling autonegotiation and
auto-MDIX.
