VHDCI Cable Precautions

All of the cables to the controller, cache module, and external cache battery use very- high-density cable interconnect connectors (VHDCI). These connectors have extraordinarily small mating surfaces that can be adversely affected by dust and movement.

Use the following precautions when you’re connecting cables that use VHDCI connectors:

Clean the mating surfaces with a blast of clean air.

Mate the connectors by hand, then tighten the retaining screws to 1.5 inch- pounds—approximately 1/4 additional turn after the connectors have fully mated.

Test the assembly by gently pulling on the cable, which should not produce visible separation.

Maintenance Port Precautions

The maintenance port generates, uses, and radiates radio-frequency energy through cables that are connected to it. This energy may interfere with radio and television reception. Do not leave a cable connected to this port when you’re not communicating with the controller.
