Connecting to the Switch Ports
This section describes how to connect to the switch, SFP module, and dual-purpose ports and 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
When you connect to servers, workstations, IP phones,
Step 1
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.
Insert the other cable end into a connector on the other device.
Step 2
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.
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.
Installing an SFP Module and Connecting to a Module Port
Grasp the SFP module on the sides, and insert it into the
Step 1
switch slot until you feel the connector snap into place.
