Hi,
Is it possible to use the redundant power supplies (PS1 / PS2) on a Dell 1750/1950 to switch a server from one source of supply (supply A) to a completely different source of supply (supply B), thereby allowing supply A to be isolated for maintenance, whilst supply B provides power, without the server having to be powered down?
Once Supply A is isolated I would look to switch both power supplies to supply B.
Proposed switching program:
Normal - Supply A - PS1 / PS2 | Supply B - no load
Step 1 - Supply A - PS1 | Supply B - PS2
Step 2 - Isolate Supply A - PS1 | Device fed from Supply B - PS2
Step 3 - Supply A - no load (isolated) | Supply B - PS1 / PS2
It's not perfectly clear from the operator manual how the device switches between its power supplies.
If anyone can provide any further information it would be very much appreciated!
MTIA
Adam.
