Here is the setup:
1 x APC UPS with SNMP Network Management Card installed.
3 x Windows 2003 Servers with Powerchute Software installed.
Powerchute has been installed and configured on the Windows 2003 Servers. It is installed and can talk to the UPS. The servers are set to start shutting down after 2 minutes.
I test the above setup by pulling the power cord from the UPS to simulate power failure. The servers all start shutting down after 2 minutes as expected. I wait for all of the servers to finish shutting down. I plug the power cable back into the UPS. The UPS goes back onto mains power, but the servers do not switch back on automatically. How can they be set to turn back on?
I have considered the BIOS settings such as "last state" etc, but in the above scenario, the servers never lost power (because the UPS never ran out of battery). Believe it or not, the above scenario is quite common in our area of late. That is, the power goes out long enough for the servers to shutdown, but not for the UPS to turn off.
Any help would be most appreciated!
