6Connecting to the Switch Ports

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

dual-purpose ports. It also describes how to verify your connections. For additional cabling

information, see the Catalyst 3560 Switch Hardware Installation Guide on Cisco.com.

Follow these steps:

The fixed ports on the Catalyst3560 Power over Ethernet (PoE) switches provide PoE support for

devices compliant with IEEE 802.3af and also provide Cisco pre-standard PoE support for Cisco

IP Phones and Cisco Aironet Access Points.

Eachof the Catalyst 3560-24PS switch 10/100 ports or the Catalyst 3560G-24PS switch 10/100/1000

ports can deliver up to 15.4 W of PoE. On the Catalyst 3560-48PS or 3560G-48PS switches, any 24

of the 48 10/100 or 10/100/1000 ports can deliver 15.4 W of PoE, or any combination of the ports

can deliver an average of 7.7 W of PoE at the same time, up to a maximum switch power output of

370 W.

By default, a Catalyst 3560 switch PoE port automatically provides power when a valid powered

deviceis connected to it. For information about configuring and monitoring PoE ports, see the switch

software configurationguide. For information about troubleshooting PoE problems, see the Catalyst

3560 Switch Hardware Installation Guide on Cisco.com.

Note For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX)

feature is enabled by default on the switch. With auto-MDIX enabled, the switch detects the

requiredcable 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

switch10/100 or 10/100/1000 Ethernet port, regardless of the type of device on the other end

of the connection.

Step1 When you connect to servers,

workstations, IP phones, 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 cable end into an RJ-45 connector on the other device.
