3.4.1 PCB Handling & General Installation
All boards should not be installed or removed with power applied.
Power must be turned off prior to insertion or removal of the PCB.
The system PCBs contain digital circuitry which, while extremely reliable, can be damaged by
exposure to excessive static electricity. When handling PCBs, a grounded wrist strap should be used
to protect the boards from static discharges. Also, use common sense when handling the PCBs. For
example, do not place a PCB in locations where heavy objects might fall on the PCB and damage
components.
To insert a PCB, hold the PCB by the injectors and, with components facing right, align the top and bottom
edge of the PCB in the card guides. Slide the card into the system and use the injectors to seat the PCB
firmly into the back plane connectors. To remove a PCB, reverse the procedure. Installation method of PCB
is shown in Figure 3.4.1.
