FreeNAS Mini XL Fuse AMP Requirements

[ryansiddle]

Hi all,

We recently bought a FreeNAS Mini XL which included an American plug, which unfortunately doesn't work within the UK. A UK plugs come with a fuse fitted. Does anyone know what AMP fuse should be used with this server? I'm assuming it's between 3-5 AMPS, but I can't seem to find any information on the data specification sheet[1] and iXsystems are unsure themselves, telling me to visit this forum.

watts=volts x amps. Or because maths, amps = watts / volts. Use the wattage of the PSU and round up.

I think it uses a 400w PSU, at 240V, I’d guess you want the 3-5A fuse as 2A would not quite be enough, but 3 would be plenty.

5A is probably what your want. That would blow well enough above the peak instantaneous draw to not cause issues but low enough the it will blow for any catistopic PSU failure/dead short.

You probably also don't want an instant blow but a so called slow blow.
