When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.
3) Follow the guidelines provided in “Preventing Electrostatic Discharge” on the
following page.
4) Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
Š To help avoid possible damage to system boards, wait five seconds after turning
off the computer before removing a component, removing a system board, or
disconnecting a peripheral device from the computer.
Š When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs. If you are
disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before connecting a cable, make sure
both connectors are correctly oriented and aligned
CAUTION
Do not attempt to service the system yourself. Follow installation
and troubleshooting instructions closely.
