Uninterrupted Power Supply Testing Procedures
- Close and save any open files before performing a test of your UPS system. You may want to leave open a "test file," but do not leave open any important or critical files. To start the testing procedure, go to the electrical breaker box and throw the circuit breaker for the room that contains your UPS connected to your computer system. Do not just unplug the UPS's power cable---this interrupts the device's ground and could damage the UPS. Throwing the circuit breaker simulates a true power outage. The UPS device should be providing power to your computer system at this point. If the unit has any display lights on the front, a light should be illuminated by a label stating the UPS is powering, a power outage has occurred or similar wording. Next, you should see a warning message on your computer system's monitor stating that you need to shut off the computer because a power outage has occurred or similar warning. Properly shut off your computer system and announce to any user signed in to properly shut off theirs if networked into the main system (announce over the intercom or other means).
- Check the condition of your UPS' battery if your UPS system fails to run your computer system and/or related hardware. Most UPS control programs have an "Event Log" that informs you of the problem. View the log, check your UPS system completely and call a authorize repairperson to repair the unit you are not able to perform the repair. Next, bring your computer system back online and check the condition of the hard drive, files, hardware connected to the computer and other related components.
- Don't "deep cycle" your UPS' battery by draining or running the battery down to an almost dead-like state. UPSs usually contain at least one lead-acid battery similar to an automobile's battery. These batteries do not have "memory" like Nickel-Cadmium batteries. Each "deep cycle" process decreases the lead-acid battery's effectiveness. One of the reasons why most UPS devices fail is due having an old battery in the unit. As the battery gets older, its life becomes shorter. That's why it is important to test your UPS device to make sure it will do its job when an electrical issue comes up. If your UPS is a few years old, have the unit inspected and serviced.
Also, make sure the device is always grounded. Do not overload the UPS and do not subject the unit to extreme temperatures, humidity and excessive static electricity.
