3.2 PREPARING THE NBR FOR INSTALLATION

This section contains the following procedures:

•Removing chassis cover

•Setting mode switches

•Setting NVRAM reset switch

•Installing SIMM upgrades

•Installing FLASH SIMMs

•Installing LDRAM and SDRAM SIMMs

•Adding/replacing EPIMs

•Adding/replacing BRIMs

•Testing the NBR

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.

!

CAUTION

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.
