Usage Guidelines

Enabling Perpetual PoE ensures that connected PoE devices continue to receive power even when the switch undergoes a reboot. This is particularly useful for devices that require constant power, such as security cameras, VoIP phones, and wireless access points, preventing downtime and ensuring continuous operation.

When configuring perpetual PoE, consider the following points:

Only S5860-24XB-U switch supports perpetual PoE.
Perpetual PoE supports maintaining uninterrupted power during a system reboot in the following scenarios.
1. Execute the command request system reboot in L2/L3 CLI operating mode.

admin@PICOS> request system reboot

b. Execute the reboot command in the Linux shell.

admin@PICOS> request system reboot

c. Reboot during the upgrade process.

d. For nos-rollback operation, if the version being rolled back to does not have Perpetual PoE configured, Perpetual PoE will not maintain uninterrupted power during the reboot in the NOS rollback process.

Before restarting the S5860-24XB-U device, you need to save the configuration by executing copy running-config startup-config in L2/L3 CLI operating mode.
Perpetual PoE will not maintain uninterrupted power in the following situations:

a. Power failure or power cycling.

b. PoE controller firmware update.
