4 Replacement Procedures

Disassembly Procedures

The cable connectors come in these two basic types:
? Pressure plate connectors
? Normal pin connectors
To remove a pressure plate connector, pull up the tabs on either side of the connector's plastic
pressure plate and gently pull the cable out of the connector. To reconnect the cable to the pressure
plate's connector, raise the pressure plate up to a satisfactory height and slide the cable into the
connector. Fix the cable to the correct position by pressing down the sides of the pressure plate so
that the plate can be flush with the sides of the connector. Grasp and pull the cable gently to check
that the cable is connected firmly. If the cable came off the connector, reinsert the cable by raising
the pressure plate up to a satisfactory height.
Normal pin connectors are used for all the other types of cables. These connectors can be installed
or removed by simply inserting them or pulling them out.

Assembly Procedures

You have to reassemble the computer after you disassembled the computer and fixed the
component that caused the problem.
When reassembling the computer, keep the following general guidelines in mind:
? Take your time to carry out the suggested instructions completely. Hurried reassembling can
often cause problems.
? Check that all the cable and connectors are fastened securely.
? Before fixing the FRUs or other parts, check that the cables are not caught by the screws or
FRUs.
? Check that all the latches are closed securely.
? Check that all the required screws are used to fix the FRUs. Using wrong screws can
damage the threads or heads of the screws or does not ensure firm FRU fixing.
After installing an FRU, make sure that the FRU and computer can work normally.
