The ExtremeXOS implementation of PoE supports
the following features:
Configuration and control of the power distribution for PoE at the
system, slot, and port levels
Real-time discovery and classification of IEEE 802.3af-compliant PDs
and many legacy devices
Support for IEEE 802.3at-compliant PDs on PoE+ devices
Support for IEEE 802.3bt
compliant PDs on PoE++ devices
Monitor and control of port PoE fault conditions including exceeding
configured class limits and power limits and short-circuit detection
Support for configuring and monitoring PoE status at the system, slot,
and port levels
Management of an over-subscribed power budget
Port LED control for indicating the link state
Support for hitless failover in a SummitStack with a master and backup
node.
(Fast PoE) Ability to provide
PoE power when the switch is powered on without waiting for boot up based on last saved PoE
state on all Universal (per port) platforms).
(Perpetual PoE) Preserve PoE
power delivery to devices during reboot on all Universal platforms.
