Field Replacement Strategy
Compaq authorized service providers will troubleshoot HSG80 subsystem problems to the
field replaceable unit (FRU) and replace the defective unit. Replacement procedures for
Subsystem FRUs addressed in this guide include the array controller, cache module,
DIMMs, ECB, and GLM.
Precautions
To prevent accidental damage to subsystem components, always follow the precautions in
this section when carrying out the procedures in this guide.
Electrostatic Discharge Precautions
Static electricity collects on all non-conducting material, such as paper, cloth, and plastic.
An electrostatic discharge (ESD) can easily damage a controller or other subsystem
component even though the discharge might not be seen or felt. ESD is a common
problem and might cause data loss, system down time, and other problems. The most
common source of static electricity is the movement of people in contact with carpets and
clothing. Low humidity increases the amount of static electricity.
Observe the following precautions whenever servicing a subsystem or subsystem
component:
s Always use an ESD wrist strap when servicing the controller or other components in
the subsystem. Make sure that the strap contacts bare skin, fits snugly, and that the
strap grounding lead is attached to a bus with a verified earth ground.
s Before touching any circuit board or component, always touch a verified earth ground
to discharge any static electricity that might be present in clothing.
s Always keep circuit boards and components away from non-conducting material.
s Always keep clothing away from circuit boards and components.
s Always use antistatic bags and grounding mats for storing circuit boards or
components during replacement procedures.
s Always keep the ESD cover over the program card when the card is in the controller. If
a card is removed, put the card in the original carrying case.
s Never touch the contacts or twist or bend the program card.
s Never touch the connector pins of a cable when one end is attached to a component or
host.
Common Replacement Information and Procedures 2 3
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.
s Clean the mating surfaces with a blast of compressed air or freon only.
s 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.
s 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.
24 HSG80 Array Controller ACS Version 8.6 Maintenance and Service Guide
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).
NOTE: A maintenance port cable (see Figure 21) is provided for connecting to a PC. This cable
has a 9-pin connector molded onto one end, to which three optional adapters can be attached
for making a maintenance terminal connection.
Use the following steps to establish a local connection for setting the initial controller
configuration:
1. Turn off the PC or terminal, and connect the maintenance port cable to the controller,
as shown in Figure 21.
a. For a PC connection, plug one end of the maintenance port cable into the
communication port of the PC; plug the other end into the controller maintenance
port.
b. For a terminal connection, refer to Figure 21 for cabling information. Adapter
part numbers are provided in Chapter 1, in section "Subsystem
Components--Exploded Views" under the specific subsystem type.

Figure 21. PC/terminal to maintenance port connection
CAUTION: Connecting a maintenance port cable between the controller and the PC
(or terminal) might cause radio and television interference. Do not leave a
maintenance port cable connected to the controller via the maintenance port unless
communication with the controller is necessary.
2. Turn on the PC or terminal.
3. Configure the terminal emulation software for 9600 baud, 8 data bits, 1 stop bit, and no
parity bit.
4. Press the Enter or Return key. The command line interface (CLI) prompt appears,
indicating that a local connection was established with the controller.
NOTE: The default data transfer rate of a new controller is 9600 baud. The maximum transfer
rate is 19200. If the current configuration uses 19200, use step 5 to establish this rate.
5. Optional step: To increase the data transfer rate to 19200 baud:
a. Set the controller to 19200 baud with one of the following commands:
SET THIS_CONTROLLER TERMINAL SPEED=19200
SET OTHER_CONTROLLER TERMINAL SPEED=19200
26 HSG80 Array Controller ACS Version 8.6 Maintenance and Service Guide
b. Configure the terminal emulation software for 19200 baud.
When entering CLI commands in a dual-redundant controller configuration, remember
that the controller connected to is "this controller" and the remaining controller is the
"other controller."
Fiber Optic Cable Cleaning Instructions
To ensure optimum performance and lifespan of the cable, it is essential that you clean the
fiber optic cables when replacing the controller. Use the polyester cloth from the cleaning
kit that came with the cable. Figure 22 shows the ferrule on a fiber optic cable.

Figure 22. Ferrule on a fiber optic cable
CAUTION: Compaq recommends cleaning the fiber optic cable only when replacing a
controller. Overcleaning might cause damage to the ferrules.
NOTE: When installing a fiber optic cable for the first time, this procedure can be omitted.
1. Using the polyester cleaning cloth that came with the cable cleaning kit, cover your
fingers and squeeze one ferrule between two fingers.
2. Rotate the cloth around the ferrule one or two times.
3. When the first ferrule is clean, move your fingers to a different area of the cloth and
repeat step 1 and step 2 for the remaining ferrule.

Cleaning a GLM
When replacing a GLM, make sure to clean the GLM receptacles to ensure optimum
performance. Use the following steps to clean a GLM:
1. Take the polyester swab from the cleaning kit that came with the fiber optic cable.
CAUTION: Do not exert excessive force when the swab reaches a stopping point, and
do not repeat this procedure frequently. Failure to comply with this caution might
cause scratching on the GLM and ultimately damage the fiber optic connection.
Overcleaning might cause damage to the GLM.
