Implementing PoE

You can configure PoE on your PoE-compliant Extreme Networks device through the CLI-based procedures presented in the section Configuring PoE. As part of your plan to implement PoE in your network, you should ensure the following:

• The power requirements of your PDs are within the limits of the PoE standards.
• Your PoE-compliant Extreme Networks device can supply enough power to run your PDs. See PoE Powered Device Classes for power ranges based on each device class.
  

  PoE Powered Device Classes

  Class	Power Output at Port	Power Range Used by Device
  0	15.4 watts	0.44 to 12.95 watts
  1	4.0 watts	0.44 to 3.84 watts
  2	7.0 watts	3.84 to 6.49 watts
  3	15.4 watts	6.49 to 12.95 watts
  4	Reserved (802.3af)	Treat as class 0 (802.3af)

If SNMP traps are enabled, the Extreme Networks device generates a trap to notify the network administrator if a power state occurs on a PD (for example, when a PD is powered up or unplugged)

If insufficient power is available for an attached PD, the corresponding port LED on the Extreme Networks device turns amber, when the port is in PoE mode. The LED also turns amber if a PoE fault occurs (for example, a short in the Ethernet cable).
