chassis. To avoid injury, use care when installing customer add-on

devices.

NOTE Before performing removal/replacement procedures, position the workstation

on a cushioned ﬂat, stable surface, such as a table top or workbench.

NOTE Installing the recommended HP replacement part in your J6700 workstation

does not affect the regulatory and safety classiﬁcations or approvals listed in

Electrostatic Discharge (ESD) Precautions

To prevent damage to the J6700 workstation, observe all of the following ESD precautions

while performing removal and replacement procedures:

• Remove all ESD-generating materials from the work area in which you will remove and

replace the workstation ﬁeld replaceable unit(s).

• Open the ESD materials provided with the replacement part kit. Unfold the black

conductive sheeting (antistatic mat) and place it under a corner of the workstation.

• Wear a static strap to ensure that any accumulated electrostatic charge is discharged

from your body to ground. Attach the static-grounding wrist strap by following the

instructions on the package. Attach the sticky end of the wrist strap to bare metal on

the rear panel of the workstation.

• Connect all equipment together, including the static-free mat, static strap, clips

attached to the wrist strap, and peripheral units.

Getting Started

Preparing Your Workstation

You must prepare your workstation before you install new upgrades or remove old

components. Here is the procedure for doing this:

1. Determine if you have the correct version of the operating system. Note that your workstation must

be running the HP-UX 11.0 operating system and the Workstation Additional Core Enchancements

(ACE) for HP-UX 11.0 (November 1999) or HP-UX 11i operating system and the Hardware

Enablement Bundle (HWE) for HP-UX 11i (June 2001) to accommodate the PA8700 upgrade. Use

the command uname -r to determine the version of your operating system. For example, it should

report B.11.00. if you are running an HP-UX 11.0 operating system. If the workstation is running

an older version of HP-UX, update the operating system software before continuing. Use the

command:

/usr/sbin/swlist -l bundle

to view what software products are loaded in your system. If the bundle list includes

B6261AA, HP-UX 11.0 with ACE (Nov., 1999), or HWEnable11i, HP-UX 11i with HWE

(June, 2001), you do not need to update HP-UX.

2. Determine the workstation’s LAN ID by entering the following command: /usr/sbin/lanscan.

The output is similar to the following:

Hardware Station Crd Hardware Net-Interface NM MAC HP DLPI Mjr

Path Address In# State NameUnit State ID Type Support Num

2.0.2 0x08000970ECC0 0 UP lan0 UP 4 ETHER YES 130

Record the LAN ID here. You will need it after installing the new system board:

Enter LAN ID: ___ ___ ___ ___ ___ ___ -___ ___ ___ ___ ___ ___

You must supply the dash (-) between the ﬁrst six digits and the last six digits

After you install the new CPU board and power on the system for the ﬁrst time, you may be prompted

for the LAN ID.

Getting Started

Safely Powering Down the J6700 Workstation

You must complete the following steps before performing any of the removal and

replacement procedures:

CAUTION Do not use the power supply interlock thumbscrew on the rear panel to power

down the workstation. This power down method may hang the operating

system in an unrecoverable state.

NOTE Remove any accessory bag(s) and their black tab screws, if present, from the

rear of the workstation. Remove any existing SCSI terminators.

1. Power off the workstation by simply pressing the power switch on the front panel of the

workstation. Also, power off the monitor and any attached peripheral devices.

If necessary, shut down the workstation by executing “shutdown -h” as user root.

This ensures that all programs are terminated and all data is saved before switching

the power off.

2. After 30 seconds, unplug the workstation’s power cord and all peripheral devices from

AC power outlets. Before attempting to move the workstation to a disassembly area,

disconnect all peripherals from the back of the system.

3. Place the workstation on a ﬂat, stable surface, such as a tabletop or ﬂoor. To protect

against scratches, remove miscellaneous debris from the work surface.

Component Remove/Replacement

Component Removal and Replacement

The procedures in this section describe how to remove the components from your

workstation. You can follow the same procedures in reverse to replace or install new

accessories or components. Observe the electrostatic discharge (ESD) precautions and the

prerequisites for removing and replacing components or accessories as discussed in

Chapter 1. Also, read any NOTEs, CAUTIONs, and WARNINGs in each component or

accessory removal and replacement procedures.

Front Bezel and Top Cover

This section describes how to remove and replace the J6700 workstation’s front bezel and

top cover.

Note that you can perform certain operations, like removing and replacing hard disk

drives, simply removing the front bezel of the workstation. Other operations require more

access to the interior of the workstation, so you will need to remove the front bezel or top

panel to perform those procedures.

CAUTION The system will not operate with the top panel removed.
