I have few customers with GE Dgital Energy UPS power supplies, mostly on-line series EP and GT with RS-232 or USB connection. Most of them have main SERVER connected directly to UPS via serial or USB cable, having UPSMAN service running on server.
UPSMAN does its job just fine regarding system shutdown, which proprly shuts down system after UPS reaches runtime limit of, let's say, 5 minutes.
But PROBLEM is system startup after mains restores. Server is not aware of power restore, so it does not power up and I have to call some secretary at remote location and ask her to press power button after each power failure.
It's not 2010 year technology, rite?
What I am thinking is to somehow configure GE DIGITAL ENERGY UPS to shut itself down after it shuts server down. For example a procedure lik this:
- mains failure
-- waiting for UPS to reach its runtime limit
- send local system SHUTDOWN command
- wait predefined time for system to shutdown (3 minutes, for example)
- then shutdown UPS (REGARDLESS of mains status!)
- then WHEN mains returns, OR IF mains is already back, wait until UPS charges to, let's say 30% capacity, and power up the UPS itself
Devices, which are connected to UPS, will detect power down and then power up event, so when power comes back, device should power up itself!
Anybody with exact instructions/settings for UPSMAN to configure UPS device like this?
