Maintenance and Service Guide
Very-high-density cable interface cable precautions
All cables that connect to the array controller, cache module, and ECB use
very-high-density cable interface (VHDCI) connectors. VHDCI connectors have
extraordinarily small mating surfaces that can be damaged by dust and cable
movement. Always take the following VHDCI precautions when servicing any
subsystem component:
■ Clean the mating surfaces with only a blast of compressed air or freon.
■ Mate the connectors by hand, then tighten the retaining screws to 3.81 cm/kg
(1.5 in/lb), approximately 1/4 of an additional turn after the connectors mate.
■ Test the cable assembly by gently pulling on the cable. There should be no
visible separation between the cable and connector.
Component precautions
System components referenced in this manual comply with regulatory standards
documented herein. Use of other components in their place might violate country
standards, negate regulatory compliance, or invalidate the product warranty.
Maintenance port precautions
The maintenance port generates, uses, and radiates radio-frequency energy
through cables that are connected to this port. This energy can interfere with radio
and television reception. Do not leave a cable connected to this port if not
communicating with array controllers.
