Unexpected shutdowns Proliant ML370 G5

[Janet Erbach]

Just an update on our unexpected shutdowns. We bought and hooked up a new APC UPS - one with the proper sine wave for the ML370 G5. The new UPS has been in place for over a month now - and not one single unexpected shutdown in that time. I think we're cured.

Janet,

What exact model if UPS you bought for your ML370 G5 server. We are having same problem here in our ML370 G5. Each PSU is connected to different UPS APC 3000VA.

We bought an APC Smart UPS 1500VA USB/SER RM2U. Here it is on the APC site:

We have not had any spontaneous re-boots since we put it in place.

Thanks for the response & link.

Junnifer,

I have been following your questions as I have a similarly posted question on a thread about ML350 G6 shut downs. I have an APC SC1500 that does not support a power outage. I see that Janet has recommended a better APC unit that claims 'sine wave.' I was caution yesterday by a UPS expert that I should use a 'double conversion' type UPS so that it is always connected to (passing through) battery and not a millisecond switch over to battery as done by a 'line interactive' UPS. I have no actual results yet, but thought I would pass this on. I am researching Eaton Power Ware UPS.

The issue as has been explained to me is that the APC Smart-UPS SC 1500VA & other UPS's that put out a "Stepped approximation to a sinewave" are not compatible with ML 370, ML 350 & higher versions of the Proliant Servers.

The Eaton Powerware 9130 'double conversion' is working great for my ML350 G6. Solved my shut down issues.

Hi, i have a similar problem.

Same server but we also have an SMART UPS 3000XL

The difference between our problem and the topi problem is that after unexpected shutdowns, the system can't restart for a minute. Try to go up but then all led blink and system go down another time. After some minute, it restart and maybe goese up for a week
