Connecting to an SFP Module

Note

When you connect to 1000BASE-T-compatible devices, be sure to use a twisted four-pair,
Category 5 or higher cable. See the

“Four Twisted-Pair Cable Pinouts for 10/100 Ports” section

on page B-7

for more information.

Connecting to an Ethernet Port

Note

You can use the mdix auto interface configuration command in the CLI to enable the automatic
crossover feature. When the automatic crossover feature is enabled, the switch detects the
required cable type and configures the interfaces accordingly. Therefore, you can use either a
crossover or a straight-through cable for all connections to an Ethernet port on the switch.

The automatic crossover feature is disabled by default. For configuration information for this
feature, refer to the switch software configuration guide or the switch command reference.

Step 2

Connect the other end of the cable to an RJ-45 connector on the other device. Repeat Steps 1 through 3
to connect each device.
