Safety Information
Follow the procedures listed below to ensure safe handling of components and to prevent harm to both you
and the HP Server:
• Use an antistatic wrist strap and a grounding mat, such as those included in the Electrically Conductive
Field Service Grounding Kit (HP 9300-1155).
• Handle accessory boards and components by the edges only. Do not touch any metal-edge connectors or
any electrical components on accessory boards.
• Do not wear clothing subject to static charge build-up, such as wool or synthetic materials.
WARNING Hazardous voltages are present inside the HP Server. Always remove AC power
from the server and associated assemblies while working inside the unit. Serious
injury may result if this warning is not observed.
Service Tools Required
Service of this product may require one or more of the following tools:
• Electrically Conductive Field Service Kit (P/N 9300-1155)
• 1/4 inch Flat Blade Screwdriver
• ACX-15 Torx® Screwdriver
Accessing a Rack Mounted Server
The hp Integrity rx4640 server is designed to be rack mounted. The following procedure explains how to gain
access to an hp Integrity rx4640 server that is mounted in an approved rack. For rack installation
instructions, review the document titled hp Integrity rx4640 Server Rack Installation Guide.
WARNING Ensure that all anti-tip features (front and rear anti-tip feet installed; adequate
ballast properly placed, etc.) are employed prior to extending the server.

Extend the Server from the Rack
NOTE Ensure that there is enough area (Approximately 1.5 meters [4.5 ft.]) to fully extend the server
out the front and work on it.
To extend the server from the rack, perform the following steps:
Step 1. Remove the T-25 screws that fasten the server to the rack.
Step 2. Flip out the two pull handles at either end of the front bezel and slowly pull the unit forward by the
handles. The server is fully extended when the rail clips are locked in place. When fully extended,
the front and top covers are fully accessible.
Accessing a Pedestal Mounted Server
The hp Integrity rx4640 server is also designed to be pedestal mounted. It is not necessary to remove the
server from the pedestal to gain access to internal components. The front bezel, front cover, and top cover may
be removed with the pedestal attached to the HP Server.
WARNING Ensure that the HP Server is properly grounded when performing remove and
replace procedures. Use and antistatic wrist strap and grounding mat similar to
those found in the HP Electrically Conductive Field Service Kit.

Removing the Front Bezel
The server does not have to be turned off to remove the front bezel.
Opening the control panel door provides access to the following components:
•Powerswitch
• System LEDs
To remove the front bezel, perform the following steps:
Step 1. Grasp the front bezel at the outer edges and pull straight out.

Removing the Covers
CAUTION Do not operate your HP Server without the front and top covers in place. Operation of the HP
Server without the front and top covers in place will result in EMI suseptibility, overheating
problems and/or system failure.
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
Removing the Front Cover
To remove the front cover, perform the following steps:
Step 1. Loosen the four captive thumbscrews that hold the front cover in place.
Step 2. Raise the cover slightly, and pull the cover toward the front of the server to free the tabs from the
slots in the center of the chassis.

Removing the Top Cover
To remove the top cover, perform the following steps:
Step 1. Loosen the two captive thumbscrews that hold the top cover in place.
Step 2. Pull the cover toward the rear of the server to free the tabs from the slots in the center of the
chassis and lift it straight up.

Removing the Memory Extender Board
The memory extender board is located directly under the top cover of the chassis. The standard memory
extender board can hold up to 16 DIMMs. The high capacity memory extender board can hold up to 32
DIMMs.
To remove a memory extender board, perform the following steps:
Step 1. Press each latch on the two extraction levers located on each side of the memory extender board.
Step 2. Pull on the extraction levers to unplug the memory extender board from the socket located on the
midplane riser board and remove the memory extender board from the chassis.

Removing the SCSI Jumper Cable
A SCSI jumper cable bridges the two SCSI connectors on the SCSI backplane when the server is configured
for simplex operation. This jumper must be removed in order to install the duplex board and to connect the
SCSI B cable.

Installing the Duplex Board
20
Installing the Duplex Board
NOTE In simplex mode, both hard disk drives, slot 0 and slot 1, are driven by SCSI channel A. When
the duplex board is installed, slot 1 hard disk drive is now driven by SCSI channel B. If HPUX
was previously installed and “whole disk vxfs” was not used, the system will no longer boot.
Refer to the HPUX Installation Guide for further information.
The duplex board is installed in the SCSI connector located nearest to the disk drive cage. The duplex board is
shipped with the duplex board bracket attached. When the duplex board is properly installed, the board is
secured to the disk drive cage by the duplex board bracket and the SCSI connector of the SCSI backplane.
SCSI B cable is connected to the connector at the immediate left of the duplex board.
Step 1. Align the bracket tabs with the slots on the side of the disk drive cage.
Step 2. Press the bracket against the disk drive cage until the bracket locks into place.
Step 3. Align the connector of the duplex board with the connector on the SCSI backplane.
