J9829A - Aruba 5400R 1100W PoE+ zl2 Power Supply

Aruba J9829A — 5400R zl2 1100W PoE+ Power Supply (hot-plug AC)

What it is

J9829A isn’t a switch or an optic — it’s a power supply module.
It’s the Aruba 1100W PoE+ zl2 hot-plug AC PSU designed for the Aruba 5400R zl2 chassis. Its job is to provide system power and a large PoE+ power pool for access modules in the 5400R platform.

Why buyers pick J9829A (plain English)

• Big PoE+ budget for a chassis
  If you’re powering lots of APs/phones/cameras from a 5400R, this is the PSU you want.

• Redundancy and load sharing
  5400R zl2 supports multiple PSUs — adding J9829A units gives N+1 resiliency and spreads PoE load.

• Hot-plug serviceability
  You can add/replace a PSU without taking the chassis down (when other PSUs are online).

• Correct zl2 platform fit
  Purpose-built for 5400R zl2, so no guessing on compatibility.
