Part number 7570221021
FUSE PANEL,-48VDC,C-SOURCE

Their site won't give you any more information about it unless you have a 
login (which I don't).  I had our purchasing person look into this at the 
time, and was told they're quite expensive...so for gear with just one DC 
input, we've been just using one source.  Right now, that's just a few 
pieces.  Just about all our DC gear supports 2 power supplies.
