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.
PoE, PoE+, and Cisco UPoE Ports
The PoE+ and Cisco Universal Power Over Ethernet (Cisco UPoE) ports use the same connectors as described
in
10/100/1000 Port Connections, on page 49
. They provide:
• PoE+ ports: Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and
support for IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port). The maximum total
PoE power in a 1RU switch is 1800 W.
• Support for Cisco-enhanced PoE.
• Support for prestandard Cisco powered devices.
• Configuration for StackPower. When the switch internal power supply module(s) cannot support the
total load, StackPower configurations allow the switch to leverage power available from other switches.
• Configurable support for Cisco intelligent power management, including enhanced power negotiation,
power reservation, and per-port power policing.
