Protecting From Power Source Problems - Gateway 960 User Manual

Protecting from power source
problems
Surge protectors, line conditioners, and uninterruptible power supplies can help
protect your server against power source problems.
Surge protectors
During a power surge, the voltage level of electricity coming into your server
can increase to far above normal levels and cause data loss or server damage.
Protect your server and peripheral devices by connecting them to a surge
protector, which absorbs voltage surges and prevents them from reaching your
server.
Warning
When your purchase a surge protector:
■
Make sure that the surge protector meets the appropriate product safety
certification for your location, such as Underwriters Laboratories (UL).
■ Check the maximum amount of voltage the protector allows to pass
through the line. The lower the voltage that the protector allows to pass
through, the better the protection for your server.
■
Check the energy absorption (dissipation) rating. The higher the energy
absorption rating, the better the protection for your server.
■ Check for line-conditioner capabilities. A line conditioner smooths out
some of the normal line noise (small voltage fluctuations) of an electrical
supply.
High voltages can enter your server through the power
cord and the modem and network connections. Protect
your server by using a surge protector. If you have a
modem, use a surge protector that has the appropriate
type of modem jack. During an electrical storm, unplug
both the surge protector and the modem and network
cables.
