System Unit Covers; Removing The Covers - NEC POWERMATE PROFESSIONAL 9000 Service Manual

If possible, use anti-static devices, such as wrist straps and floor mats.
T
Always hold a chip or board by its edges to avoid touching the components.
T
Take care when connecting or disconnecting cables. A damaged cable can cause a
short in the electrical circuit. Misaligned connector pins can cause damage to
system components at power-on.
When installing a cable, route the cable so it is not pinched by other components
and is out of the path of the system unit cover. Prevent damage to the connectors
by aligning connector pins before you connect the cable.
T
When disconnecting a cable, always pull on the cable connector or strain-relief
loop, not on the cable.

SYSTEM UNIT COVERS

The following subsections describe how to remove and replace the system unit side covers.

Removing the Covers

Before installing optional hardware inside your computer, you must first remove the one or
both of the side covers on the system unit. The left side cover must be removed whenever
the interior of the system unit is accessed. Less frequently, the right side cover must be
removed. The following procedure applies to either cover.
NOTE: For systems with LANDesk
Manager, a chassis intrusion is reported to the
Client Manager whenever the cover is removed.
When this occurs, a LANDesk Client Manager
Notification message displays every time the
system is turned on. Close the window to remove
the message from the screen. To prevent the
message from appearing again, clear the message
from the system (launch LANDesk Client
Manager, open the Tools menu, click
and click ).

CAUTION: Electrostatic discharge can damage
computer components. Discharge static
electricity by touching a metal object before you
remove the system unit cover.
