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 X435; and X465, 5320, 5420, and 5520 (per port) series switches only).
• (Perpetual PoE) Preserve PoE power delivery to devices during reboot (ExtremeSwitching X465 , X435, 5320, 5420, and 5520 series switches only).
