Summary of PoE Features

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 (ExtremeSwitching X465 and X435 series switches only).
• (Perpetual PoE) Preserve PoE power delivery to devices during reboot (ExtremeSwitching X465 and X435 series switches only).
