PoE Ports

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) capable and source power to PD devices connected to the downlink ports. A switch can
source POE power of up to 30W per port.
Depending on the switch model and the number of PoE ports, the maximum switch power output varies. For
the 24-port switch models, the power range is between 195W to 370W. For the 48-port switch models, the
power range is between 180W and 740W. 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 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
• 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.

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.
