This guide provides instructions for removing the system board from your Dell Power-
Edge 4300 system and installing the new system board.
Your kit consists of a replacement system board, a basic input/output system (BIOS)
and firmware upgrade diskette, and instructions.
%HIRUH<RX%HJLQ
Before shutting down your system, view the system configuration screen s in the Sys-
tem Setup program and/or the Resource Configuration Utility (RCU) and make a
record of the settings (see your Users Guide for complete information). You will be
installing a new system board and you must set the options to the same settings.
The upgrade procedure requires a #2 Phillips screwdriver. In addition, you should use
a wrist grounding strap for electrostatic discharge (ESD) protection. Read the safety
instructions in the following section.

1. Turn off your computer and any peripherals.
2. Ground yourself by touching an unpainted metal surface on the chassis,
such as the metal around the card-slot openings at the back of the com-
puter, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the com-
puter chassis to dissipate any static electricity that might harm internal
components.
3. Disconnect your computer and peripherals from their power sources. Also,
disconnect any telephone or telecommunication lines from the
computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs; if you are dis-
connecting this type of cable, press in on the locking tabs before disconnecting
the cable. As you pull connectors apart, keep them evenly aligned to avoid bend-
ing any connector pins. Also, before you connect a cable, make sure both
connectors are correctly oriented and aligned.
Handle components and cards with care. Dont touch the components or con-
tacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a
component such as a microprocessor chip by its edges, not by its pins.

To remove the expansion cards, perform the following steps:
1. Open the expansion-card access door (see Figure 2).
Record the location of each expansion card so that each card is installed into the
same slot on the new system board.
2. Disconnect any cables attached to the expansion cards.
Be sure to record the location of each cable before you disconnect it.

3. Install all expansion cards in the same slots on the new system board (use the
notes you made when you removed the cards from the original system board).
4. Install any internal panels, shrouds, or brackets.
5. Install the computer cover.
6. Install the power supplies :
a. Slide the power supply almost all the way into its bay, allowing it to extend
out about a half centimeter (a quarter of an inch).
b. Rotate the handle back toward the power supply while fitting the two legs of
the handle into the cutouts in the chassis wall, while at the same time press-
ing the power supply the rest of the way into the bay.
c. Push the locking bar to the right (or down if the system is in rack-mount posi-
tion) until the latch snaps into place, securing the power supply.
NOTE: The power supply will not operate unless the handle is snapped all the
way into the securing position.
7. After starting up the system, run the Asset Tag utility.
The Asset Tag utility allows you to enter a unique asset tag number for the new
system board that you or your organization assign to the system. For information
on running this utility, refer to your system Users Guide.
8. Compare the system configuration information with the copy of the system con-
figuration settings you made in Before You Begin, found earlier in this guide.
Restore the system configuration information to the settings for the original
board.
9. If you are using a padlock to secure your system, reinstall the padlock.
NOTE: After removing and replacing the system board, the chassis intrusion
detector will cause the following message to be displayed at the next system
start-up:
ALERT! Cover was previously removed.
10. Reset the chassis intrusion detector by entering the System Setup program and
setting Chassis Intrusion to Not Detected. See Using the System Setup Pro-
gram, in your system User's Guide for instructions.
NOTE: If a setup password has been assigned by someone else, contact your
network administrator for information on resetting the chassis intrusion detector.
