10/100/1000 Ethernet Ports

The 10/100/1000 Ethernet ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length
is 328 feet (100 meters). The 100BASE-TX and 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.
For information about the 10/100/1000 Ethernet port connections and specifications, see the
"10/100/1000 Ethernet Port Connections" section on page 2-19

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.
Cisco UPOE ports: Support for powered devices on all four Ethernet signal pairs (up to 60 W Cisco
UPOE per port).
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.
