Who this suits and who it does not

Network administrators replacing a failed unit or adding redundancy in supported Aruba switches will find a direct fit. Buyers who need a different wattage, a different output voltage or a supply for non-Aruba hardware should look elsewhere.

Deciding specification

The 54 V DC output is the single parameter that must match the switch chassis exactly. Verify the part number JL819A against the hardware compatibility list before ordering.
