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