Virtues of the Uninterruptible Power Supply

What happens to your IT when you have a power cut? You’re in the middle of working on some important document when the screens go black, the phones cut out and the office becomes silent except for people making confused noises.

If you’re lucky, you can reboot the server, your document might be able to auto-recover, and the phones will come back up once the VoIP router has been restarted. Power surges can make mischief though, and do serious damage to your hardware. You might find that servers and routers won’t successfully restart, and then you’re facing hours of down-time and a major disruption for your business.

How do you avoid this sticky situation? You can invest in a device known as a UPS – an Uninterruptible Power Supply. In essence, it’s a large battery back-up box. You should plug your server into it, and ideally your switch and router also, in order to stay connected to the internet in the event of a power cut. It’s not a miracle worker – your PCs will still go off, as a UPS can only support a small handful of critical devices. It can only support you for a limited amount of time too, normally between ten minutes and one hour. Power cuts in the UK tend to be mercifully brief though, and the UPS will buy you the time you need to shut your server down safely, which means that it will restart properly when full power is restored to the building.

In addition, if you have an internet-dependent VoIP phone system, you really need to have your VoIP router and switch plugged into a UPS, or internet connection will be lost while the power is off, and your telephone system with it. No one wants customers getting abruptly cut off because of a power cut, so best to make sure your phone system is protected.
