Replacing the cache directory card
When the maintenance procedures direct you to replace the cache directory card, carefully follow this procedure.
Attention: Perform this procedure only if you
are directed from an isolation procedure or a maintenance analysis
procedure (MAP).
Attention: Static electricity can
damage this device and your system unit. To avoid damage, keep this
device in its antistatic protective bag until you are ready to install
it. To reduce the possibility of electrostatic discharge, read the
following precautions:
- Limit your movement. Movement can cause static electricity to build up around you.
- Handle the device carefully, holding it by its edges or its frame.
- Do not touch solder joints, pins, or exposed printed circuitry.
- Do not leave the device where others can handle and possibly damage the device.
- While the device is still in its antistatic package, touch it to an unpainted metal part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.)
- Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set the device down, place it on its static-protective package. (If your device is a controller, place it component-side up.) Do not place the device on your system unit cover or on a metal table.
- Take additional care when handling devices during cold weather, as heating reduces indoor humidity and increases static electricity.
