Load-sharing redundant power supplies J9828A, max 630W, system power (12V), 275W of PoE power; J9829A, 630W max system (12V) power, 900W max PoE power; J9830A, 630W max, system (12V) power, 2500W max PoE power can be installed in the back of the 5400R zl2 switches. To provide redundancy, each power supply should be connected to different AC power sources. Then, if one AC power source fails, the switch will continue to run.
NOTE: Any combination of J9828A, J9829A and J9830A power supplies can be used in the same switch. However, HPE recommends using the same model of power supplies in a switch. | |
CAUTION: The switch redundant power supply is hot swappable, but, as indicated by the caution statement on the power supply, it must be disconnected from AC power before being installed or removed.

Because the switch can run on a single supply, removing a redundant supply will not interrupt switch operation. However, with a single power supply system will power on Interface module up to 630W. The rest of the Interface modules are powered on the priority of the slot. The slot A has the highest priority and the slot L has the lowest priority.
When power is restored from a second (or more) power supplies, a system reload or interface module reset is not required to restore operation to slots G-L. The 5400R modules will restart by themselves when power recovers.
To reset the interface modules, pull each module out about half way and then re-seat them. Do this for each module in slots G-L. For more information regarding power see the:
