Disassembly and Reassembly 3-3
!
All screws are Phillips-head, unless otherwise specified.
!
Observe each cable connector before attempting to unplug.
!
Use care in disconnecting and connecting cables to prevent breakage. Do not pull on the
cable, pull only on the connector.
!
Wherever possible, label any cable connector before removing it. Note where the connector
goes and in what position it was installed.
On completion of any reassembly, perform a power-on test. If a fault occurs, verify that the
reassembly was performed correctly.
Before handling boards or chips, ground yourself to release static.
Most procedures require removal of the system’s cover. Some procedures also require removing
the front panel. Procedures for removing the cover and front panel are included in this section.
Safety Precautions
Observe safety rules when working inside the system and when handling computer components.
Avoid electric shock or personal injury by observing the following warning.
Before removing the system cover or front panel, turn off the power
and unplug the system power cable. Power is removed only when the power cable is unplugged.
Static electricity and improper installation procedures can damage computer components.
Protect computer components by following these safety instructions.
Electrostatic discharge (ESD) can damage computer components.
Discharge static electricity by touching a metal object before removing the system cover.
!
Avoid carpets in cool, dry areas. Leave boards and chips in their anti-static packaging until
ready to be installed.
!
Dissipate static electricity before handling any system components (boards, chips, memory
modules) by touching a grounded metal object, such as the system’s unpainted metal
chassis.
If possible, use antistatic devices, such as wrist straps and floor mats.
!
Always hold a chip or board by its edges. Avoid touching the components on the chip or
board.
!
Take care when connecting or disconnecting cables. A damaged cable can cause a short in
the electrical circuit.
!
When installing a cable, route the cable so it is not pinched by other components and is out
of the path of the system cover.
!
Prevent damage to the connectors by aligning connector pins before you connect the cable.
Misaligned connector pins can cause damage to system components at power-on.
!
When disconnecting a cable, always pull on the cable connector or strain-relief loop, not on
the cable itself.
