PCI-953 Single Board Computer User’s Guide
³
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:
 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.

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 except as explained in
this user’s guide. Follow installation and troubleshooting
instructions closely.
