Connecting 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.
Connecting to 10/100 and 10/100/1000 Ports
Follow these steps:
Step 1 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.
Step 2 Insert the other cable end into an RJ-45 connector on the other device.
The fixed ports on the Catalyst 3560 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.
Each of 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
device is connected to it. For information about configuring and monitoring PoE ports, see the switch
software configuration guide. 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
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
switch 10/100 or 10/100/1000 Ethernet port, regardless of the type of device on the other end
of the connection.
