Avoiding power source problems
Surge suppressors, line conditioners, and uninterruptible power supplies can
help protect the server against power source problems.
Surge suppressors
During a power surge, the voltage level of electricity coming into the server
can increase far above normal levels and cause data loss or system damage.
Protect you computer and peripherals by connecting them to a surge
suppressor, which will absorb voltage surges and prevent them from reaching
your computer.
When purchasing a surge suppressor:
■ Make sure the surge suppressor meets the appropriate product safety
certification for your location, such as Underwriters Laboratories (UL) or
Conformite European (CE).
■ Check the maximum amount of voltage the suppressor allows to pass
through the line. The lower the voltage that the suppressor allows to pass
through, the better the protection for the server.
■ Check the energy absorption (or dissipation) rating. The higher the energy
absorption rating, the better the protection for the server.
■ Check line-conditioner capabilities. A line conditioner smooths out some
normal line noise (small voltage fluctuations) of an electrical supply.
