UPS (Uninterrupted Power Supply)

These are a very good idea, even a necessity, to have. Especially on servers and sensitive communications equipment.
A UPS will

  • filter any power spikes, protecting your equipment from overload and failure of components, often serious
  • protect via battery backup for short outages, keeping equipment up especially if there are remote offices.
  • protect via extended battery backup for longer periods, and software will trigger server to cleanly shutdown based on configuration when batteries are low.
