2.2 Opening the Housing Panels
The system housing has one front door and two side panels. Always
observe the following ESD (electrostatic discharge) precautions
before installing any system component:
1. Do not remove any system component from its packaging unless
you are ready to install it.
2. Wear a wrist grounding strap before handling electronic
components. Wrist grounding straps are available at most
electronic component stores.
DO NOT attempt the procedures in the following
sections unless you are confident of your
capability to perform them. Otherwise, ask a
service technician for assistance.
2.2.1 Removing the Left and Right Panels
A microswitch is allocated on the left side of the housing panel. It
helps indicate whether the panel is removed or intact.
To remove the left or right panel:
1. Turn off the power to the system unit and unplug all cables.
2. Place the system unit on a flat, steady surface and lock the
wheels by pressing down the levers.
3. Remove the screws of the left or right panel. Set the screws
aside. You will need them when replacing the panels.
4. Pull out the panel and detach it.
