Does anyone actually wire up both the A side and B side to a single DC power supply and use diodes to keep the two supply grids separate?
We've built a number of "joiner" boxes in-house at KTHNOC; basically an aluminium box with rectifier bridge and heatsink, and screw terminals. We use them for 2511 terminal servers and similar. So, yes.
DC also avoids bulky AC power cords...and not only are the wires less bulky, but you'll likely cut them to the actual length needed. Since DC wiring is usually screwed down, they don't get bumped or accidentally pulled out of the outlets as often.
YMMV, but 4 times 2x10mm² + 16mm² PE (The DC connects for a 12n16 GSR) I find bulkier than 4 10A power cords ;-). You are right on spot about the tidy/sturdy part, though. - -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE We're sysadmins.
