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 740 W or 370 W, depending on the switch model. Intelligent
power management allows flexible power allocation across all ports.
For switches with a 740 W power budget, you can budget the PoE and PoE+:
• 15.4 W of PoE output on 48 ports
• 30 W of PoE+ on 24 ports
For switches with a 370 W power budget, you can budget the PoE and PoE+:
• 15.4 W of PoE output on 24 ports
• 7.7 W of PoE output on 48 ports
• 30 W of PoE+ on 12 ports

Product Overview
10/100/1000 Ports
• Total power budget can be allocated among the 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 100BASE-TX 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.

Management Ports
The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
• Ethernet management port
• RJ-45 console port (EIA/TIA-232)
• USB mini-Type B console port (5-pin connector)
The 10/100 Ethernet management port connection uses a standard RJ-45 crossover or straight-through cable.
The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port
connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same
as the RJ-45 console interface speeds.
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.

Product Overview
USB Type A Port
This illustration shows a 5-pin mini-Type B USB port.
Figure 2: 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.
USB Type A Port
The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB
keys).
The USB Type A port provides these features:
The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB devices with port
densities of 128 MB, 256 MB, 1 GB, 4 GB, 8 GB are supported). When combined with stacking, you can
upgrade other switches in the stack from an USB key inserted in any switch within the stack. Cisco IOS
software provides standard file system access to the flash device: read, write, erase, and copy, as well as the
ability to format the flash device with a FAT file system. It provides you with the ability to automatically
upgrade the internal flash with the USB drive’s configuration and image for emergency switch recovery using
USB auto-upgrade. This feature checks the internal flash for a bootable image and configuration and if either
image or the configuration is not available, then the USB drive is checked for boot images and configuration.
If the boot image and configuration are available, these are copied to flash for the reboot.
SFP and SFP+ Module Slots
The switch has either two or four 1-Gigabit SFP or two 10-Gigabit SFP+ module slots. The slots marked
SFP+ support both SFP and SFP+ modules. The SFP slots support only the SFP modules.

The Cisco RPS 2300 (model PWR-RPS2300) supports the Catalyst 2960-X switch.
Warning
Attach only the following Cisco RPS model to the RPS receptacle: RPS2300. Statement 370
Connect the switch and the redundant power system to different AC power sources.
Use this cable for the RPS: CAB-RPS2300-E.
Cisco RPS 2300
The Cisco RPS 2300 is a redundant power system that can support six external network devices and provide
power to one or two failed devices at a time. It senses when the internal power supply of a connected device
fails and provides power to the failed device, preventing loss of network traffic. For more information, see
the Cisco Redundant Power System 2300 Hardware Installation Guide on Cisco.com at this URL: http://
www.cisco.com/en/US/products/ps7148/prod_installation_guides_list.html
The Cisco RPS 2300 has two output levels: –52 V and 12 V with a total maximum output power of 2300 W.
All supported and connected switches can simultaneously communicate with the RPS 2300. You can configure
these RPS 2300 features through the switch software:
• Enable RPS active or standby mode for each connected switch
• Configure switch priority for RPS support
• List the connected switches and the power-supply module sizes
• Obtain reports when a switch is powered by the RPS
• Obtain status reports for the RPS power-supply module
• Read and monitor backup, failure, and exception history
AC Power Connector
Note
This applies to the Catalyst 2960-X switches.
The switch is powered through the internal power supply. The internal power supply is an autoranging unit
that supports input voltages between 100 and 240 VAC. Use the supplied AC power cord to plug it into an
AC power outlet.
