3.2.1 Removing Chassis Cover
This section describes how to remove the chassis cover from the NBR.
Remove the chassis cover to install BRIMs, set the mode switch bank,
and install SIMM memory upgrades.
Do not remove the cover from the NBR while power is applied
to the unit.
Do not power up the unit, for any reason, until the cover and
screws are in place. Hazardous voltages are present that could
cause damage to the unit or personal injury.
The components and boards associated with the NBR are
sensitive to static discharges. Be sure to use an antistatic wrist
strap and observe all static precautions during this procedure.
Failure to do so could result in damage to the NBR.
