10/100/1000 Ethernet Ports

The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum

cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category

Category

5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category

3 or Category 4 UTP cable.

For more information about the 10/100/1000 Ethernet port connections and specifications, see the

“10/100/1000 Ethernet Port Connections” section on page 2-26 and Appendix B, “Connector and Cable

Specifications.”

PoE Ports

The 10/100/1000 PoE ports provide PoE support for devices compliant with IEEE 802.3af and also

provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

Each port can deliver up to 15.4 W of PoE. With the 1150-W power-supply module, the

Catalyst

3750E-48PS and Catalyst 3560E-48PS switches can deliver 15.4 W on all 48 ports. With the

750-W power-supply module, the switches can deliver 15.4 W of PoE on any 24 of the 48 ports, or any

combination of the ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum

switch power output of 370 W. On a per-port basis, you can control whether or not a PoE port

automatically provides power when an IP phone or an access point is connected.

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 at this location:

For more information about the required power-supply module, PoE port connections, and PoE

specifications, see the

“Power-Supply Modules” section on page 1-15, the “PoE Port Connections”

section on page 2-26, and Appendix B, “Connector and Cable Specifications.”
