10/100 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 all 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
•
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 10/100 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328
feet (100 meters). The 10BASE-T and 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.
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.
For information about port connections and port specifications, see the
Port Connections” section on page 2-24
and
Appendix B, “Connector and Cable Specifications.”
Note
The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
