76 Managing the Server
Line conditioners
A line conditioner protects the server from the small fluctuations in voltage
from an electrical supply. Most systems can handle this variation (line noise)
without problems. However, some electrical sources include more line noise
than normal. Line noise can also be a problem if the server is located near,
or shares a circuit with, a device that causes electromagnetic interference, such
as a television or a motor.
Some surge suppressors and uninterruptible power supplies include simple
line-conditioning capabilities.
Uninterruptible power supplies
Use a standby uninterruptible power supply (UPS) to protect your server from
data loss during a total power failure. A UPS uses a battery to keep your server
running temporarily during a power failure and lets you save your work and
shut down your server. You cannot run your server for an extended period
of time while using only the UPS.
Maintain and manage your hard drive
Regular maintenance can keep your hard drive operating efficiently and good
file management can keep the server free of unwanted files while making
important files secure and easier to find.
Hard drive maintenance utility
If you are using the Windows NT operating system, you can help maintain
the performance of your hard drive by regularly using Check Disk.
Using Check Disk in Windows NT
Bad sectors are parts of a hard drive or diskette that will not hold data. A lost
allocation unit is a group of sectors that has lost its place in the table that
the operating system uses to locate files. Check Disk checks the hard drive
for bad sectors or lost allocation units and lets you fix them.
Important For other operating systems, such as Windows 2000 or
Novell Netware, refer to the appropriate operating system
manual.
