Product Overview
The Catalyst 3560 switch—also referred to as the switch—is an Ethernet switch to which you can 
connect devices like workstations, Cisco Wireless Access Points, Cisco IP Phones, and other network 
devices such as servers, routers, and other switches. This chapter provides a functional overview of the 
Catalyst 3560 switch. These topics are included:

Setting Up the Switch
See the Catalyst 3560 Switch Getting Started Guide for instructions on how to use Express Setup to 
initially configure your Catalyst switch. The getting started guide provides switch management options, 
basic rack-mounting procedures, port and module connections, power connection procedures, and 
troubleshooting help.
For instructions on setting up your switch using the command-line interface (CLI), see Appendix D, 
“Configuring the Switch with the CLI-Based Setup Program.”
Features
The 24- and 48-port Catalyst 3560 switches can be deployed as backbone switches, aggregating 
10BASE-T and 100BASE-TX Ethernet traffic from other network devices. The Catalyst 3560-8PC and 
the Catalyst 3560-12PC-S compact switches provide the same Power over Ethernet (PoE) connectivity 
and can be deployed outside the traditional wiring closet environment, such as in office workspaces and 
classrooms. The switches are hot-swappable. See the switch software configuration guide for examples 
of how you might deploy the switch.
For power redundancy, all but the Catalyst 3560 8- and 12-port switches include connections for an 
optional Cisco RPS 2300 or Cisco RPS 675 that operates on AC power and supplies backup DC power 
to the switches.

The 10/100/1000 ports on the Catalyst 3560G-48TS switch are grouped in pairs. The first member of the 
pair (port 1) is above the second member (port 2) on the left, as shown in Figure 1-10. Port 3 is above 
port 4, and so on. The SFP module slots are numbered 49 to 52.
Figure 1-10 Catalyst 3560G-48TS Switch Front Panel
10/100 and 10/100/1000 Ports
You can set the 10/100 ports to operate in any combination of half duplex, full duplex, 10 Mb/s, or 
100 Mb/s. You can set the 10/100/1000 ports to operate at 10 or 100 Mb/s in half or full duplex or 
at 1000 Mb/s in full duplex.
You can set both the 10/100 and the 10/100/1000 ports for speed and duplex autonegotiation, in 
compliance with IEEE 802.3ab. (The default setting is autonegotiate.)
You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces if the 
speed is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit Ethernet 
interfaces if the interface speed is 1000 Mb/s.
When set for autonegotiation, the port senses the speed and duplex settings of the attached device 
and advertises its own capabilities. If the connected device also supports autonegotiation, the switch 
port negotiates the best connection (the fastest line speed that both devices support and full-duplex 
transmission if the attached device supports it) and configures itself accordingly. In all cases, the 
attached device must be within 328 feet (100 meters).
WarningVoltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if 
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. 
Avoid using such interconnection methods, unless the exposed metal parts are located within a 
restricted access location and users and service people who are authorized within the restricted 
access location are made aware of the hazard. A restricted access area can be accessed only through 
the use of a special tool, lock and key or other means of security. Statement 1072
100BASE-TX and 1000BASE-T traffic requires Category 5 cable. 10BASE-T traffic can use 
Category 3 or Category 4 cables. 110/100/1000 ports2SFP module slots

OL-6337-07
Chapter 1      Product Overview
Front Panel Description
When you connect the switch to workstations, servers, routers, and Cisco  IP Phones, be sure that the 
cable is a straight-through cable. When you connect the switch to switches or hubs, use a crossover 
cable. When using a straight-through or crossover cable for 1000BASE-T connections, be sure to 
use a twisted four-pair, Category 5 cable for proper operation. Pinouts for the cables are described 
in Appendix B, “Connector and Cable Specifications.”
You can use the mdix auto interface configuration command to enable the automatic 
medium-dependent interface crossover (auto-MDIX) feature. When the feature is 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 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. 
The auto-MDIX feature is enabled by default on switches running Cisco  IOS Release 12.2(18)SE or 
later. For releases between Cisco  IOS Release  12.1(14)EA1 and 12.2(18)SE, the auto-MDIX feature 
is disabled by default. For configuration information for this feature, see the switch software 
configuration guide or the switch command reference.
PoE Ports
The10/100 and 10/100/1000 PoE ports on the switch provide PoE support for devices compliant 
with IEEE 802.3af and Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet 
Access Points. 
Each of the Catalyst 3560-8PC, 3560-12PC-S, 3560-24PS, and 3560V2-24PS switch 10/100 ports 
or the Catalyst 3560G-24PS switch 10/100/1000 ports deliver up to 15.4 W of PoE. 
On the Catalyst 3560-48PS, 3560G-48PS, and 3560V2-48PS switches, any 24 of the 48 10/100 or 
10/100/1000 ports delivers 15.4 W of PoE, or any combination of the ports delivers an average of 
7.7 W of PoE at the same time, up to a maximum power output of 370 W. 
The Catalyst 3560-12PC-S switch delivers a maximum power output of approximately 125 W total 
PoE power.
On a per-port basis, you can control whether or not a PoE port automatically provides power when 
an IP phone or an access point is connected. The device manager, Network Assistant, and the CLI 
provide PoE settings for each 10/100 or 10/100/1000 PoE port: 
 –Auto: When you select the Auto setting, the port provides power only if a valid powered device, 
such as an IEEE 802.3af-compliant powered device, a Cisco prestandard IP phone, or a Cisco 
prestandard Cisco access point, is connected. The Auto setting is the default. 
 –Never: When you select the Never setting, the port does not provide power even if a Cisco 
IP phone or an access point is connected.
You can connect a Cisco IP Phone or Cisco Aironet Access Point to a Catalyst 3560 PoE switch 
10/100 or 10/100/1000 port and to an AC power source for redundant power. The powered device 
might change to the AC power source as its primary power source when connected to it. In that case, 
the PoE port becomes the backup power source for the powered device. 
If the primary source fails, the second power source becomes the primary power source to the 
powered device. During the power transfer, an IP phone might reboot or reestablish link with the 
switch.
For information about configuring and monitoring PoE ports, see the switch software 
configuration guide. For information about Cisco IP Phones and Cisco Aironet Access Points, see the 
documentation that came with your IP phone or access point.

See the release notes for the latest list of supported SFP modules.
SFP Modules
The switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections. 
These transceiver modules are field-replaceable, providing uplink interfaces when inserted in an 
SFP module slot. Use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic 
SFP module. Use a Category 5 cable with RJ-45 connectors to connect to a copper SFP module.
For more information about SFP modules, see your SFP module documentation or the release note for 
your switch software. 
SFP Module Patch Cable
The switch supports the SFP module patch cable (CAB-SFP-50CM=), a 0.5 meter, copper, passive cable 
with SFP module connectors at each end (see Figure 1-11). 
Figure 1-11 SFP Module Patch Cable
The SFP module patch cable can connect only two Catalyst 3560 switches. To connect a 
Catalyst 3560 switch to other Catalyst series switches, you must use the SFP modules specified in the 
“SFP Module Cable Specifications” section on page B-4.
See “Inserting and Removing the SFP Module Patch Cable” section on page 2-18 for more information 
about using the SFP module patch cable.
Dual-Purpose Port
You can configure a dual-purpose port as either a 10/100/1000 port or as an SFP module port. Each port 
is considered as a single interface with dual front ends—an RJ-45 connector and an SFP module 
connector. The dual front ends are not redundant interfaces. The switch activates only one connector of 
the pair at a time.
By default, the switch dynamically selects the interface type that first links up. However, you can use 
the media-type interface configuration command to select the RJ-45 connector or the SFP module 
connector. For information about configuring speed and duplex settings for a dual-purpose uplink, see 
the software configuration guide.
Each uplink port has two LEDs. One shows the status of the RJ-45 port, and one shows the status of the 
SFP module port. The port LED is on for the active connector.
