[AusNOG] ATS recommendation

[Nicholas Hobbs]

Hi Rhys,

We run a number (~6 or so) of the APC ATS' for some of our critical (but only 1 PSU) gear with no issues.
We did however have one that was faulty from new that switched between A&B feeds a bit randomly and was replaced because there was no reason it should have been switching.

Have you called APC to try and troubleshoot the issue?
I'm not sure how the ATS could trip the UPS/Breakers as there should only ever be one active circuit unless there's a fault or overload condition.
What size UPS' are behind the ATS? 3000VA or so?

Nick

Hi Guys

We have a very small server room with one rack drawing around 8 amps.
I thought I was clever and installed an APC ATS to run the kit that only has single feel power input.

Well its been a disaster, final straw was 4am today when it caused both UPS's to error and trip all breakers.
Bypassing the ATS fixed it.

I'm thinking of abandoning the ATS idea or trying another brand like Eaton

Does anyone have any thoughts on this?

Thanks

Rhys
