Removing the Front Panel Display
Removing the Front Panel Display
This library contains very sensitive electrical components. Follow the
proper procedures for preventing electrostatic discharge (ESD). Use
wrist-grounding straps and anti-static mats when removing and
replacing cards and assemblies.
Failure to follow proper procedures could damage the circuitry.
1. Remove the display cover and chin plate underneath the display on
the existing library module. The screw locations are indicated in
Figure 1-4. Save these screws to later reinstall the display cover and
chin plate.
Your library might only be one module instead of two modules, which is
shown in Figure 1-4.
2. Remove the display cover by lifting it upward and away from the
library.
