Replace the cache directory card only if you are directed
to do so by an isolation procedure or a maintenance analysis procedure
(MAP).
Attention: This procedure should only
be performed if 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 anti-static protective bag
until you are ready to install it. To reduce the possibility of electrostatic
discharge, follow the precautions listed below:
- 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 anti-static 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.
To replace the cache directory card, perform
the following steps:
- Remove the controller using the remove procedures for the
model or expansion unit on which you are working.
- Locate the cache directory card A .
- Unseat the connector on the cache directory card by wiggling
the two corners over the connector using a rocking motion. Then, lift
the cache directory card off the connector and out of the guides on
the cache battery rail.
- Install the replacement card A by
inserting it into the guides on the cache battery rail and then seating
it on the connector.
- Install the controller using the installation procedures
for the model or expansion unit on which you are working.
