Which computer equipment does use 42V?
« on: October 17, 2020, 03:30:30 pm »
Yesterday I found a very massive lot of PSUs. They have two rails of 42V with 60A.
They are marked "SONY/CISCO", but I cannot find any information about them.

I am just curious: 48V is for POE, but ... what about 42V? And 60A ?!? 

I cannot imagine a computer equipment that requires so much current at 42V :-//

Could be in connection with a server farm with massive lead-acid battery backup. 42 V would fit in that scenario.

Those are most likely PSU modules for Catalyst 6500 switches.

Wonder if 42 is just the minimum it can take, sounds like something made to run on a 48v system, which usually floats at 54v.  Usually used in telecom.
