PoE Ports
The ports provide PoE support for devices compliant with IEEE 802.3af and IEEE 802.3at and also provide
PoE support for Cisco IP Phones and Cisco Aironet Access Points. The PoE switch ports are Power Source
equipment (PSE) and Power Device (PD) capable and source power to PD devices connected to the downlink
ports. A switch can source POE power of up to 30.8W per port.

Product Overview
PoE Ports
Depending on the switch model and the number of PoE ports, the maximum switch power output varies
between 236.89 W to 440.66 W. On a per-port basis, you can 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 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.
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.
Console Ports
The console 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.

Product Overview
10/100/1000 Ports
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 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, and 8 GB are supported). 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.
SFP Module Slots
The switch has four 1-Gigabit SFP module slots. The SFP slots support only the SFP modules.
For Cisco SFP modules documentation, including compatibility matrixes, refer to this URL: http://

Internal Power Supply
All the switches are powered through their internal power supplies. The internal power supply is an autoranging
unit that supports input voltages between 100 and 240 VAC (max of 90V to 264V). The AC frequency range
of the power supply is 50Hz~60Hz. Plug the AC power cord into the AC power connector and into an AC
power outlet.
Security Slot
The switches have security slots on the rear panel. You can install an optional cable lock, such as the type
that is used to secure a laptop computer, to secure the switch.
