ML350G4p and UPS


I have attached a UPS (APC Smart-UPS) to my ML350 with USB cable.

If the power is down, the UPS works and stop the server when the battery is low. After that, the power supply of the server is still supplied (the ON/OFF light is orange).

After that, 2 cases :
- the UPS is switched OFF (no more battery). when the power comes back, the UPS switch ON and the server starts automatically. it's OK.

- the UPS is not alreday switched OFF and the power comes back : the server doesn't start automatically... but I want that it start automatically

do you how to do it ? I think this is a BIOS options but I don't know which one. Note that the option Automatic Power-On is activated.

Hi Thomas, two things you may check in the BIOS pressing F9 when prompted, go to "Server Availability" then go to Automatic Power-On, and enable it. If the option is already enabled, the server's BIOS is set to work as it should the issue here jumps to another topic. In this case the UPS, this kind of things does not happen when using HP's UPS, the HP's servers are made to work specially with HP's UPS, in fact if you or a Customer call us regarding this type of issue, we'll say that unfortunately the option is not supported since the UPS is not a HP.

This also could be an issue with Windows 2003 assuming that is what you are running.
Although this is labeled for HP UPS SW this patch should resolve your issue.

Follow the intructions after applying as there is a policy setting that must be done.

Let us know.
