Product Overview

The Catalyst 3560-CX and 2960-CX switches 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.

Note
PoE+ ports 1 to 6 are Gigabit Ethernet 1/0/1 to 1/0/6. The remaining ports are 10-Gigabit Ethernet 1/0/1 and 1/0/2. However, depending on the SFP type, the rightmost ports will either be 10-Gigabit Ethernet 1/0/3 and10-Gigabit Ethernet 1/0/4 or Gigabit Ethernet 1/0/7 and Gigabit Ethernet 1/0/8.

PoE and PoE+ Ports

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

The maximum switch power output is either 124 W or 240 W, depending on the switch mode. Intelligent power management allows flexible power allocation across all ports.

For switches with a 124 W power budget, you can budget the PoE and PoE+:

  • 15.4 W of PoE output on 8 ports

  • 30 W of PoE+ output on 4 ports

For switches with a 240 W power budget, you can budget the PoE and PoE+:

  • 15.4 W of PoE output on 12 ports

  • 30 W of PoE+ output on 8 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 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 10BASE-T, 100BASE-TX, 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.


Note

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

10/100/1000 Ports

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

Multigigabit ports

The Multigigabit ports can be configured to auto-negotiate multiple speeds on switch ports, and support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category5e cables, and up to 10 Gbps over Category6 and Category 6A cables.

The Multigigabit ports support PoE and PoE+ for all the supported speeds and cable types. The following table lists the cable types and speed.

Management Ports

The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.

  • RJ-45 console port (EIA/TIA-232). The RJ-45 console port connection uses an RJ-45-to-DB-9 female cable.

  • USB mini-Type B console port (5-pin connector).

If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not require special drivers.

The 4-pin mini-Type B connector resembles the 5-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B.

This illustration shows a 5-pin mini-Type B USB port.

Figure 3. USB Mini-Type B Port



With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console port without affecting Windows HyperTerminal operations.

The console output always goes to both the RJ-45 and the USB console connectors, but the console input is active on only one of the console connectors at any one time. The USB console takes precedence over the RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive. Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.

You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45 console if the USB console has been activated and no input activity has occurred on the USB console for a specified time.

After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and reconnect the USB cable to reactivate the USB console. For information on using the CLI to configure the USB console interface, see the software guide.

SFP and SFP+ Module Slots

The switch has either two 1-Gigabit SFP or 10-Gigabit SFP+ module slots. The slots marked SFP+ support both SFP and SFP+ modules. The SFP slots support only the SFP modules.

For Cisco SFP and SFP+ modules documentation, including compatibility matrixes, refer to this URL: http:/​/​www.cisco.com/​en/​US/​products/​hw/​modules/​ps5455/​products_​device_​support_​tables_​list.html
