Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. When not in use, keep the module in the static-shield bag. Follow these guidelines when you handle any module:Touch a grounded object to discharge static potential.Wear an approved wrist-strap grounding device.Do not touch the bus connector or connector pins.Do not touch circuit components inside the module.If available, use a static-safe work station.
Disconnect all connectors from the board (1). Verify each label for each connector for subsequent installation. Refer to Illustration 2 for wire connections.
Disconnect the nine white plastic standoffs that connect the board (1) to the left panel.Note: The board (1) must be removed from the standoffs without bending the board (1) .
Compress the head of each standoff so that the board (1) is not locked, but the board (1) is still attached to the standoff.
Remove the board (1) from all standoffs at the same time.Installation Procedure
