Very-High-Density Cable Interface (VHDCI) Cable Precautions

All cables that connect to the controller, cache module and ECB use 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 a blast of compressed air or freon only.
• Mate the connectors by hand, then tighten the retaining screws to 1.5 in/lb (0.17
N-m), 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 might interfere with radio and
television reception. Do not leave a cable connected to this port when not
communicating with the controller.

Establishing a Local Connection to the Controller

Communication with a controller is done locally or remotely. Use a local connection
to configure the controller for the first time. Use a remote connection to the host
system for all subsequent configuration tasks. Refer to the controller installation and
configuration guide that came with the platform kit for details.
A maintenance port, located on the front of the controller, provides a convenient way
to connect a PC or terminal to the controller for troubleshooting or configuring the
controller. This port accepts a standard RS-232 jack from any EIA-423 compatible
terminal or a PC with a terminal-emulation program. The maintenance port supports
serial communications with a default value of 9600 baud (using 8 data bits, 1 stop bit,
and no parity bit).
