Questions about this item

Will the 460 W hot-plug unit slide into the standard power-supply bay of a ProLiant DL180 G6 or DL160 G6 without extra rails?

Yes — the supply is built to the ProLiant hot-plug form factor used in the DL180 G6 and DL160 G6, so it seats directly in the server's redundant PSU bay with no additional mounting hardware.

What is the step installers most often miss when swapping this 591555-201 supply in a running DL180 G6?

After the old unit is unlatched and removed, the replacement must be pushed firmly until the latch clicks and the amber LED clears; skipping that final seat-and-latch leaves the supply detected but not powered.
