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.

10/100/1000 Ports

Depending on the switch model and the number of PoE ports, the maximum switch power output varies
between 91.66 W to 150.11 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

Product Overview

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

SFP Module Slots

The switch has two 1G SFP module slots. The SFP modules provide copper or fiber-optic connections to
other devices. These transceiver modules are field replaceable, and provide the uplink interfaces when installed
in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors
for copper connections. The SFP slots support only SFP modules.

For Cisco SFP modules documentation, including compatibility matrixes, refer to this URL:

Note

If you insert a 10G SFP+ in to a 1G SFP module slot and vice versa, you need to clear the existing configuration
by running the default-interface <interface-number> command on the mapped ports. For more information
about the command, refer to the Software Configuration Guide.

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

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.
