Perpetual PoE and Fast Boot PoE

Perpetual PoE and fast boot PoE are two new enhancements that can be configured on ICX 7550 switches to allow brief or no power downtime. These enhancements provide high availability to the PD devices by powering them even when a software process is not running on the switch. You must configure perpetual PoE or fast boot PoE on a per-port basis. When configured, the PDs will not lose power while reloading and will have a brief power-down time when power-cycled. By default, perpetual PoE and fast boot PoE are disabled in FastIron 08.0.95.

Perpetual PoE provides uninterrupted power to the connected PDs even when the PSE switch is rebooting or reloading.

Fast boot PoE provides power to the powered devices as soon as the PSE switch is turned on without waiting for the system to boot up.

Use the inline power poe-ha command to enable the perpetual PoE and fast boot PoE. Perpetual PoE allows the PoE to remain active and to remember the last PoE settings within 2 seconds after receiving the power, assuming the PD remains the same. If a change of the PD occurs, disable or enable the inline power command to re-check the PD type or class.
