7.10.1 Handling Modules
Caution!
Care must be taken to when inserting or withdrawing modules to avoid damage to
underside components.
Modules must be kept orthogonal, i.e. at 90 degrees to the unit, to avoid catching
underside components on the chassis.
Figure 7.9 Inserting and Withdrawing Modules
Caution!
Do not plug in modules with excessive force as this may result in damage to the
module connector or other components. If any significant resistance to inserting a
module is felt, withdraw the module slightly and check for obstructions.
7.10.2 Electrostatic Discharge
Warning!
Static electricity can damage electronic components. To avoid damage, keep
modules in their static-protective package until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
•
Where possible ensure that antistatic protection is worn (for example an earthed
antistatic wrist strap, an ankle or heel strap).
