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.

Important For other operating systems, such as Windows 2000 or Novell Netware, refer to the appropriate operating system manual.

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.
