It's an old Dell R410, with supplies DPS-500RB (12V only) and D480E-S0 (12/5/3.3V). If the second one died, the first one can't make the server still run, as there's no 5V or 3.3V!


from the manual:

" 4.1 Power Supplies
" The R410 is powered by a non-redundant 480 W power supply (Dell P/N
" F238K) and redundant 500 W power supply (Dell P/N F649J).

Seems to be some sort of marketing speak (by which I mean incompetent or
intentional unthruths).

It seems the 500W unit is hotplugabble and can replaced from the back
of the machine (like on machines with redundant power-supplies)

However the 480W is cabled to the main board and you need to open the case and
unlug the cables to replace it.

Sorted - Im building it from spare parts, and hadnt realised you dont use both supplies. You either use just one multi-voltage one, which connects straight to the motherboard, or you use two 12V ones, with a power distribution board to make the lower voltages - eg.

Oh well, I have an extra supply now which I'll convert for GPUs.
