Cisco Catalyst 2960-XR Getting Started Manual

Step 3

Replace the dust covers when you remove the FlexStack cables from the connectors.

Caution

Removing and installing the FlexStack cable can shorten its useful life. Do not remove and insert the cable

more often than is absolutely necessary.

Connecting to the Switch Ports

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

Connecting to the 10/100/100 or 10/100/1000 PoE+ Ports

The fixed ports on the Catalyst 2960-X or 2960-XR Power over Ethernet Plus (PoE+) switches provide:

• PoE+ support for IEEE 802.3at-compliant powered devices

• PoE support for IEEE 802.3af-compliant powered devices

• Support for Cisco enhanced PoE (ePoE)

They also provide Cisco prestandard PoE support for Cisco IP phones and Cisco Aironet Access Points. See the switch hardware

guide for information on PoE budgeting. By default, a switch PoE port automatically provides power when a compliant device is

connected, including ePoE, PoE, and PoE+.

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

Note

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 module port on the switch, regardless of the type of device on the other end of the

connection.

Procedure

Step 1

Insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/100/1000 port when you connect to servers,

workstations, IP phones, wireless access points, and routers. Use a crossover, twisted four-pair, Category 5 cable when

you connect to other switches, hubs, or repeaters.

Step 2

Insert the other cable end into an RJ-45 port on the other device.

Connecting to SFP and SFP+ Module Slots

Some switch models have SFP module slots and others have SFP+ module slots. The SFP slots support only the SFP modules. The

SFP+ slots support both SFP and SFP+ modules. For a list of supported modules, see the release notes on Cisco.com. For detailed

instructions on installing, removing, and connecting to SFP modules, see the documentation that came with the SFP module.
