There are four choices to make when selecting power protection:
- Does this equipment need power protection?
Since surge protectors are so inexpensive, and provide protection against power surges. We recommend that all electronic equipment be plugged into surge protectors.
- Does this equipment need uninterrupted power?
If the equipment is critical to the operation of your business, or requires several minutes to safely shut down, it should be connected to an uninterruptible power supply. For example network servers are constantly writing data to their hard disks. If power were lost during a data write, the data in memory would be lost. Additionally, servers need several minutes to safely shut down. We recommend that all servers be connected to uninterruptible power supplies. Note that uninterruptible power supplies typically have surge-protected outlets.
- How long do I want my equipment to be able to run in case of a blackout?
The total wattage used by the equipment you want to keep running in case of a blackout, times the length of time you need your equipment to run will determine whether you should implement uninterruptible power supplies or emergency power generation equipment. Many UPS's are sized to allow computers attached to them to run for 10-25 minutes. This is sufficient time for users to logoff their computers, write unsaved data to disk, and perform an orderly shutdown of the operating system.
For most small businesses, the cost of emergency power generation equipment is prohibitive, costing several thousand dollars or more. Most businesses choose to implement uninterruptible power supplies (UPS).
- Do I need software that will automatically shut down my computer and save my files in the event of a blackout?
Many UPS’s have software that will automatically sense a power outage and perform an orderly shutdown of a computer connected to it. We strongly recommend automatic shutdown software for all network servers.
