Precautions
Follow these precautions when carrying out the procedures in this book.
Electrostatic Discharge Precautions
Static electricity collects on all nonconducting material, such as paper, cloth, and
plastic. An electrostatic discharge (ESD) can easily damage a controller or other
subsystem component even though you may not see or feel the discharge. Follow
these precautions whenever you're servicing a subsystem or one of its components:
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 its grounding lead is attached to a bus that is a verified earth
ground.
s Before touching any circuit board or component, always touch a verifiable earth
ground to discharge any static electricity that may be present in your clothing.
s Always keep circuit boards and components away from nonconducting 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 you remove the card, put it in its original carrying case. Never touch
the contacts or twist or bend the card while you're handling it.
s Never touch the connector pins of a cable when it is attached to a component or
host.
Component Precaution
System components referenced in this manual comply to regulatory standards
documented herein. Use of other components in their place may violate country
standards, negate regulatory compliance, or invalidate the warranty on your product.
xxi
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.

Electrostatic Discharge
Electrostatic discharge (ESD) is a common problem and may 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 also
increases the amount of static electricity. You must discharge all static electricity
prior to touching electronic equipment. Follow the precautions in Electrostatic
Discharge Precautions given in the Preface whenever you are replacing any
component.
23
Preparation Procedures
Establishing a Local Connection to the
Controller
You can communicate with a controller locally or remotely. Use a local connection to
configure the controller for the first time. Use a remote connection to your host
system for all subsequent configuration tasks. See the Quick Setup Guide that came
with your platform kit for details.
The maintenance port provides a convenient way to connect a PC or terminal to the
controller so that you can troubleshoot and configure 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 default values of 9600 baud using 8 data bits, 1 stop bit, and no parity.
NOTE: There are two maintenance port cables shown in Figure 21. One has a 9-
pin connector molded onto its end for a PC connection. An optional cable is
available for a terminal connection.
Follow these steps to establish a local connection for setting the controller's initial
configuration:
1. Turn off the PC or terminal, and connect it to the controller, as shown in Figure
21.
a. For a PC connection, plug one end of the maintenance port cable into the ter-
minal; plug the other end into the controller's maintenance port.
b. For a terminal connection, refer to Chapter 1 for cabling information.
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.

CAUTION: The cables connecting the controller and the PC (or terminal)
may cause radio and television interference. Only connect a PC or
terminal to the controller via the maintenance port when you need to
communicate with the controller.
4. Press the Enter or Return key. The CLI prompt appears, indicating that you have
established a local connection with the controller.
5. Optional: to increase the data transfer rate to 19200 baud:
NOTE: If you are replacing a controller, do not increase the data transfer rate to
19200 baud. A new controller is set to 9600 baud (default).
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
b. Configure the PC or terminal for 19200 baud.
When you are entering CLI commands in a dual-redundant controller configuration,
remember that the conroller to which you're connected is "this controller" and the
remaining controller is the "other controller."

26 Replacement Procedures
Fibre Channel Optical Cable Cleaning
Instructions
It is essential to clean the fibre channel optical cables when replacing the controller to
ensure optimum performance and lifespan of the cable. You will need the polyester
cloth from the cleaning kit that came with your cable. Figure 22 shows the ferrule on
an optical cable.
Ferrule
CXO6503A
Figure 22. Ferrule on an Optical Cable
NOTE: When you use a cable for the first time, it is not necessary to follow this
procedure.
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 steps 1 and 2 for the remaining ferrule.
CAUTION: It is only necessary to clean the fibre channel optical cable
when replacing a controller. Overcleaning may cause damage to the
ferrules.
27
Cleaning the GLM
When you replace the GLM, it is important to clean its receptacles to ensure optimum
performance. Use the following steps to clean the GLM:
1. Obtain the polyester swab from the cleaning kit that came with your fibre channel
optical cable.
2. Gently insert the lint-free polyester swab into the transmit-side of the optical
GLM cavity (see Figure 23).

CAUTION: Do not exert excessive force when the swab reaches its
stopping point, and do not repeat this procedure frequently. Failure to
comply with this caution may cause scratching on the GLM and
ultimately damage the optic connection. Overcleaning may cause
damage to the GLM.
3. Carefully dust out the cavity by rotating the swab tip back and forth one or two
times.
4. Repeat steps 1 and 2 for the receiving side of the optical GLM cavity.

28 Replacement Procedures
Shutting Down the Subsystem
Use the following steps to shut down a subsystem:
1. From a host console, stop all host activity and dismount the logical units in the
subsystem.
2. Connect a PC or terminal to the maintenance port of one of the controllers in
your subsystem.
3. Shut down the controllers. In single controller configurations, you only need to
shut down "this controller." In dual-redundant controller configurations, shut
down the "other controller" first, then shut down "this controller" with the
following commands:
SH UTDOWN OTHER_CONTROLLER
SH UTDOWN THIS_CONTROLLER
When the controllers shut down, their reset buttons and their first three LEDs are
lit continuously. This may take several minutes, depending on the amount of data
that needs to be flushed from the cache modules.
4. Turn off the power to the subsystem.
CAUTION: If you are shutting down the controller for longer than one
day, perform the steps in the next section, "Disabling and Enabling the
External Cache Batteries," to prevent the write-back cache batteries
from discharging.
Disabling and Enabling the External Cache
Batteries
Use the following steps to disable the External Cache Batteries (ECBs):
NOTE: The ECB SBB may contain one or two batteries, depending on the
configuration.
29
1. Press the battery-disable switch located on each battery within the ECB SBB.
The switch is the small button labeled SHUT OFF next to the status LED (see
Figure 24). Hold each switch in for approximately five seconds. The ECB's
status LED will flash once and then shut off. Make sure you perform this
procedure on both ECB 1 and ECB 2, if appropriate.
2. The batteries are no longer powering the cache module.
