6 Connecting to the Switch Ports

This section describes how to connect to the fixed switch ports and to the SFP module ports. The switch in the illustrations

might be different from your switch, but the instructions apply to all Cisco ME 3400E switches.

Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The switch detects

the required cable type for copper Ethernet connections and configures the interfaces accordingly. You can use either a

crossover or a straight-through cable for connections to a copper 10/100, 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.

Caution To prevent damage to the SFP module, make sure that you verify the proper orientation of the module by consulting

the module documentation before you install it.

Step1 When you connect to servers, workstations,

customer-premises equipment (CPE), wireless access points,

and routers, insert a straight-through, twisted four-pair,

Category 5 cable in a switch 10/100 or 10/100/1000 port.

Use a crossover, twisted four-pair, Category 5 cable when you

connect to other switches, hubs, or repeaters.

Step2 Insert the other end of the cable into a connector on the other device.

Step1 Grasp the SFP module on the sides, and insert it into the switch slot

until you feel the connector snap into place.

Step2 Insert an appropriate cable into the SFP module port. Insert the

other cable end into the other device.
