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 (ExtremeSwitchingX435;
and X465 (per port) series switches only).
(Perpetual PoE) Preserve PoE
power delivery to devices during reboot (ExtremeSwitching X465 and X435 series switches only).
