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.
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation
and follow proper ESD procedure to reduce the risk of damage to components.
Quanmax strongly encourages you to follow proper ESD procedure, which can
include wrist straps and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
