10/100/1000 PoE and PoE+ Port Connections

The ports provide PoE support for devices compliant with IEEE 802.3af and 802.3at (PoE+), and also provide
Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power when an IP phone
or an access point is connected.
Caution
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a
suitable and safe earth ground before connecting them to the switch or other devices.
Caution Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling
to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at (PoE+) compliant
devices. You must remove any cable or device that causes a PoE fault.
Procedure
Step 1
Connect one end of the cable to the switch PoE port.
Step 2 Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when
both devices have established a link.
The port LED is amber while STP discovers the topology and searches for loops. This process takes about
30 seconds, and then the port LED turns green. If the LED is off, the other device might not be turned on,
there might be a cable problem, or there might be a problem with the adapter in the other device.
Step 3
Reconfigure and reboot the connected device, if needed.
Step 4 Repeat Steps 1 through 3 to connect each device.
