A few weeks ago we had a powercut that lasted several hours. During that time the UPS's depleted to zero and were useless when the power finally came back after being off over 2 hours.
Following on from that we had several small drops in power which meant that the UPS's didn't have time to recharge themselves in order to prevent another system failure. Although Powerchute wouldnt have saved us from the power failures it would have prevented the untidy shutdowns on many of the systems as the UPS connected to them simply stopped working.
With that in mind we decided to sort out the UPS software, in the past this was never an issue but the risk of losing a server meant that putting this into place was more important than before as the infrastructure of the system on the whole had got bigger and with that the UPS's were under more strain than before.
Installation is easy with the Powerchute Network Shutdown that is free from http://www.apc.com. Install the software on each of the clients connected to the UPS in question then go to the IP address of the network card in your browser.
Installing the client should have added it to the list of IP addresses to shutdown when required, check that this is the case in the network management website. A simple fix to what could have been a painful problem.
