So, that's not a very good endorsement :) Idk why you'd use a fuse in a PDU. The management interface can be rebooted without taking anything down on the TrippLite but it's at a colo and it *shouldn't* time out like it does. I think of this like a vehicle computer - if it goes down, you might still drive for a little but get ready for a crash. On Jun 23, 2013 9:00 PM, "Luke S. Crawford" <lsc@prgmr.com> wrote:
I also have had good experience with (used) servertech/century/power tower (I think all the same brand) - very inexpensive; if you are in santa clara I have some spare 2u 16 port 208v (20a/c19) units.
Here is something a buddy wrote up when we were wiring them to the user-accessable power on/off menu:

My new rack is all avocent PM3001-401 units. Used, of course; but the feature I was after was per-port power monitoring.
I haven't quite gotten 'em all the way figured out yet. One thing I see as a negative (but might be positive?) is that they have fuses, not breakers. I don't know if this provides better protection; I do know that when my buddy overloaded one of them in testing, I had to replace fuses, rather than just switching a breaker back. (also, when a different buddy plugged a ancient desktop (so old the PSU wasn't auto-switch) with the power input switch set to 110 in, it blew some of the fuses in the PDU (and took out the rack) - it didn't damage any of the other servers on the pdu (other than taking out the PDU; but everything came back up when I swapped it with my spare.)
Also note, uh, the servertech and the avocent and I think all the other PDUs I've seen can reboot the management interface without flipping the outlets. I did it a bunch when I was getting familiar with the avocent.
Yeah. I think I need to give fewer buddies access to production.
Nobody takes hardware seriously enough. I can find people I trust with root, and that trust doesn't seem misplaced. But I let them touch the hardware? and they fuck it up. So I end up doing almost all the hardware stuff myself.

I'll also throw out recommendations for ServTech PDUs. They have an affordable line of PDUs with static transfer switches that are particularly attractive for all your single-power-supply devices.
