Product Overview

The Catalyst 3560-C and 2960-C of switches, also referred to as the switch, are Ethernet switches to which you can connect devices such as Cisco IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers, routers, and other switches.

You can deploy these switches outside of the traditional wiring closet environment, such as in office workspaces, hotel rooms, slot machines, kiosks, and classrooms. The switch is suitable for deployments where there are space and power constraints (access to power outlets).

See the switch software configuration guide for deployment examples.

10/100 and 10/100/1000 Fast Ethernet Downlink Ports

You can set the 10/100 ports to operate at 10 or 100 Mb/s in full-duplex or half-duplex mode. You can set the 10/100/1000 ports to operate at 10, 100, or 1000 Mb/s in full-duplex or half-duplex mode. You can also set these ports for speed and duplex autonegotiation. (The default setting is autonegotiate.)

Automatic medium-dependent interface crossover (auto-MDIX) is a feature that allows the switch interface to detect the required cable connection type (straight-through or crossover) and automatically configure the connection appropriately. With auto-MDIX enabled, you can use either a straight-through or crossover type cable to connect to the other device, and the interface automatically corrects for any incorrect cabling. In all cases, the attached device must be within 328 feet (100 meters)

The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is
328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or
Category 4 UTP cable.

For information about port connections and port specifications, see the "Connecting to the 10/100 and 10/100/1000 Ports" section.

PoE Ports (Switches with PoE Ports)

The PoE and PoE+ ports provide PoE support for devices compliant with 802.3af and 802.3at and also provide Cisco prestandard PoE and PoE+ support for Cisco IP Phones and Cisco Aironet Access Points.

All 8 downlink ports on the Catalyst 2960CPD-8PT-L, 2960C-8PC-L, 2960C-12-PC-L, and the 3560CPD-8PT-S and are PoE-capable. Each port can supply 15.4 W of PoE per port.

The maximum switch power output for the Catalyst 2960CPD-8PT-L is 22.4 W, and for the
Catalyst 3560CPD-8PT-S is 15.4 W. The maximum switch power output for the Catalyst 2960C-8PC-L and the 2960C-12-PC-L is 123.2 W.

All 8 or 12 downlink ports on the Catalyst,3560CG-8PC-S, 3560C-8PC-S, and 3560C-12PC-S switches are PoE+ capable. The maximum switch power output is 123.2 W. You can budget the PoE and PoE+:

• 15.4 W of PoE output on eight ports

• 30 W of PoE+ on four ports

On a per-port basis, you control whether or not a port automatically provides power when an IP phone or an access point is connected.

The 10/100/1000 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or
Category 4 UTP cable.

Cisco intelligent power management capabilities include enhanced power negotiation, power reservation, and per-port power policing. For information about configuring and monitoring PoE ports, see the switch software configuration guide on Cisco.com.

For information about port connections and port specifications, see the "Connecting to the 10/100 and 10/100/1000 Ports" section.

Note The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.

PoE Pass-Through

The Catalyst 2960CPD-8PT-L and 3560CPD-8PT-S switches provide PoE pass-through. The
Catalyst 2960CPD-8PT-L is powered either through the 10/100/1000 PoE uplink ports receiving power from a PoE or PoE+ switch or through an auxiliary power adapter. The Catalyst 3560CPD-8PT-S is powered through the 10/100/1000 PoE uplink ports receiving power from a PoE+ switch or through an auxiliary power adapter. If the switch has surplus power (see Table 1-2), it can power other PoE-capable devices such as IP phones, access points, and so on. See Figure 1-6.

See the "Powering the Switch" section for information on powering the switches.

PoE Uplink Ports (Catalyst 2960CPD-8TT-L, 2960CPD-8PT-L, and 3560CPD-8PT-S)

The 10/100/1000 PoE uplink ports on the Catalyst 2960CPD-8TT-L and 2960CPD-8PT-L can receive power from a PoE or PoE+ switch. The 10/100/1000 PoE uplink ports on the Catalyst 3560CPD-8PT-S can receive power from a PoE+ switch. You can connect each of the uplink ports to different PoE switches or to the same PoE switch. See Figure 1-6.

Note You can also use an external auxiliary power adapter that connects to the rear of the switch. You can order it from your Cisco representative. See the "Auxiliary Power Adapter" section for information.

PoE-Capable Downlink Ports (Catalyst 2960CPD-8PT-L, 3560CG-8PC-S, 3560CPD-8PT-S, 2960C-8PC-L, 2960C-12PC-L, 3560C-8PC-S, and 3560C-12PC-S)

Depending upon the available PoE budget, these switches can power other PoE-capable devices such as IP phones, access points, and so on. See Table 1-2 for PoE budgeting information. See Figure 1-6.

For information on powering the switches, see the "Powering the Switch" section.

USB Type A Port

Some models have an USB Type A port. This port provides access to external Cisco USB flash devices (also known as thumb drives or USB keys). The port supports Cisco USB flash drives with capacities from 64 MB to 1 GB.

Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy, as well as the capability to format the flash device with a FAT file system.

For more information about the switch management ports, see the switch software configuration guide and the command reference on Cisco.com.

Dual-Purpose Ports

You can configure the dual-purpose ports on the switch as either 10/100/1000 ports or as SFP-module ports. You can set the 10/100/1000 ports to autonegotiate, or you can configure them as fixed 10, 100, or 1000 Mb/s (Gigabit) Ethernet ports.

By default, the switch selects the medium for each dual-purpose port (10/100/1000BASE-T or SFP). When a link is achieved on one media type, the switch disables the other media type until the active link goes down. If links are active on both media, the SFP-module port has priority, but you can use the media-type interface configuration command to manually designate the port as an RJ-45 port or an SFP port.

You can configure the speed and duplex settings consistent with the selected media type. For information on configuring interfaces, see the switch software configuration guide.

SFP Modules

The switch Ethernet SFP modules provide connections to other devices. These field-replaceable transceiver modules provide the uplink interfaces.The modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper connections.

You can use any combination of these supported SFP modules:

•GLC-LH-SM=

•GLC-SX-MM=

•GLC-ZX-SM=

•GLC-BX-D=

•GLC-BX-U=

•GLC-FE-100FX=

•GLC-FE-100LX=

•GLC-FE-100BX-D=

•GLC-FE-100BX-U=

•CWDM SFPs

For information about SFP modules, see your SFP module documentation and the "Installing SFP Modules" section. For cable specifications, see the "SFP Module Cables" section on page B-3.

Management Ports

You can connect the switch to a PC running Microsoft Windows or to a terminal server through either the RJ-45 console port or the USB mini-Type B console port, also referred to as the USB-mini console port.

•RJ-45 console port. The RJ-45 connection uses an RJ-45-to-DB-9 female cable.

•USB-mini console port (5-pin connector). The USB connection uses a USB Type A-to-5-pin mini-Type B cable.

The USB-mini console interface speeds are the same as the RJ-45 console interface speeds.

To use the USB-mini console port, you must install the Cisco Windows USB device driver on the device that is connected to the USB-mini console port and that is running Microsoft Windows.

Note For information about downloading the Cisco USB device driver, see the "Installing the Cisco Microsoft Windows USB Device Drivers" section.

With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the console port does not affect Windows HyperTerminal operations. Mac OS X or Linux require no special drivers.

Note The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B. See Figure 1-7.

Figure 1-7 USB Mini-Type B Port

The configurable inactivity timeout reactivates the RJ-45 console port if the USB-mini console port is activated, but no input activity occurs for a specified time period. When the USB-mini console port deactivates due to a timeout, you can restore its operation by disconnecting and reconnecting the USB cable. For information on using the CLI to configure the USB-mini console interface, see the switch software guide.

LEDs

You can use the switch system and port LEDs to monitor switch activity and performance.
