Power Over Ethernet
Commands—Summit 300 and 400-24p
Switches and Alpine PoE Module
Power over Ethernet (PoE) is an effective method of supplying 48 VDC power to certain types of
powered devices (PDs) through Category 5 or Category 3 twisted pair Ethernet cables. Powered devices
include the Altitude 300 wireless port, IP telephones, laptop computers, web cameras, and other
devices. With PoE, a single Ethernet cable supplies power and the data connection, reducing costs
associated with separate power cabling and supply. PoE for ExtremeWare includes a method of
detection to assure that power is delivered only to devices that meet the IEEE 802.3af specification for
PoE.
NOTE
PoE features are supported only by the Summit 300 series switches, the Summit 400-24p switch, and
the Alpine FM-32Pi PoE Module.
Summary of PoE Software Features
The Alpine FM-32Pi PoE Module, Summit 300 series switches, and Summit 400-24p switch support the
following PoE software features:
•
Configuration and control of the power distribution for PoE at the system (slot) level (Alpine
FM-32Pi module only)
•
Configuration and control of the power distribution for PoE at the port level
•
Real-time detection of powered devices on the line
•
Monitor and control of PoE fault conditions
•
Support for configuring and monitoring PoE status at the port level
•
Management of an over-subscribed power budget
Port Power Management
When you connect PDs, the PoE device automatically discovers and classifies those that are
AF-compliant. The following functions are supported for delivering power to specific ports:
•
Enabling the port for discovery and classification
•
Enabling power delivery to a discovered device
