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.
