Below you will find brief information for Ethernet switch Catalyst 3560 24PS, Ethernet switch Catalyst 3560 24TS-S, Ethernet switch Catalyst 3560 48PS, Ethernet switch Catalyst 3560 48TS-S, Ethernet switch Catalyst 3560V2 24PS. The Catalyst 3560 switches are Ethernet switches that can be deployed as backbone switches, aggregating 10BASE-T and 100BASE-TX Ethernet traffic from other network devices. They have features that include Power over Ethernet (PoE) connectivity and can be deployed outside the traditional wiring closet environment, such as in office workspaces and classrooms. Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

Product Overview
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 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:

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.

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).
Warning Voltages 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.

•
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.

Chapter 1 Product Overview
Front Panel Description
Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.
SFP Module Slots
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 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.

Cisco RPS
Depending on the switch model, you can connect the switch to either of these Cisco redundant power systems (RPS) to provide backup power if the switch power supply fails:
•
“Cisco RPS 2300” section on page 1-19
•
“Cisco RPS 675” section on page 1-19
Connect the switch and the Cisco RPS to the same AC power source. Use the RPS connector cable supplied with the RPS to connect the RPS to the switch.
Note
When an RPS is connected to the Catalyst 3560V2-24TS-SD switch, the switch is not Network
Equipment Building Systems (NEBS) compliant.
Note
The Catalyst 3560-8PC and Catalyst 3560-12PC-S switches do not have an RPS connector.
For complete information about the Cisco RPS products, including compatibility matrixes listing the supported RPS for each Catalyst 3560 switch, see the RPS documents on Cisco.com: http://www.cisco.com/en/US/products/ps7148/prod_installation_guides_list.html
Cisco RPS 2300
The Cisco RPS 2300 is a redundant power system that supports six network switches and provides power to one or two failed switches at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic.
The Cisco RPS 2300 has two output levels: -52 V and 12 V. The maximum output power depends on the installed power-supply modules.
Cisco RPS 675
The Cisco 675 RPS is a redundant power system that supports six network devices and provides power to one failed switch at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic.
The Cisco RPS 675 has two output levels: –48 V and 12 V. The maximum output power is 675 W.
Console Port
You can connect the switch to a PC by means of the console port and the supplied RJ-45-to-DB-9 female cable. If you want to connect the switch console port to a terminal, you need to provide an
RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the “Connector and Cable
Specifications” section on page B-1 .
