Removing and Installing Server Module Components
The following procedures in this section describes how to remove and install system components and server module components
The following procedures describe how to remove and install the following components:
Your system contains two hot-pluggable power supplies that are accessible from the system back panel. You can hot-plug a power supply if two power supplies are installed. The system requires that one power supply is installed to operate.
NOTICE: The power supplies are hot-pluggable. The system requires one power supply to be installed for the system to operate. The system is in the redundant mode when two power supplies are installed. Remove and replace only one power supply at a time in a system that is turned on. Operating the system with only one power supply installed for extended periods of time can cause the system to overheat. |
Figure 6-1. Removing and Installing a Power Supply
NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is working properly. The power-on indicator will turn green to indicate that the power supply is functioning properly (see Figure 2-4). |
Your system contains four hot-pluggable fans.

The system is upgradeable to 2 GB by installing two 1-GB registered SDRAM memory modules. You can purchase memory upgrade kits as needed.
NOTE: The SDRAM memory modules must be PC-133 compliant. |
See Figure A-3 to locate the memory module connectors.
After the system completes the POST routine, it runs a memory test.
The system detects that the new memory does not match the system configuration information, which is stored in NVRAM. The monitor displays an error message that ends with the following words:
Press <F1> to continue; <F2> to enter System Setup
The system should have already changed the value in the System Memory setting to reflect the newly installed memory.
Each server module contains two memory module connectors on the system board that can accommodate from 128 MB to 2 GB of registered memory modules.
Starting with the connector nearest the side of the server module board, the memory module sockets are labeled "DIMM A" and "DIMM B" (see Figure A-3). When you install memory modules, install the first memory module in connector DIMM A before installing a memory module in connector DIMM B.
If your system contains only one memory module, install the memory module in connector DIMM A.
CAUTION: Before you perform this procedure, see "Safety FirstFor You and Your System" in "Troubleshooting Your System." |
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide. |
The memory module connector has an alignment key that allows the memory module to be installed in the connector in only one way.
When the memory module is properly seated in the connector, the memory module connector ejectors should align with the ejectors on the other connectors with memory modules installed.

To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary microprocessor.
If your server module contains only one processor, it must be installed in the CPU 1 socket and a terminator must be installed in the CPU 2 socket.
NOTE: The second microprocessor must be of the same type as the first. If the two microprocessors are different speeds, both will operate at the speed of the slower microprocessor. |
Each microprocessor and its associated cache memory are contained in a PGA package that is installed in a ZIF socket on the server module board.
The following items are included in the microprocessor upgrade kit:

NOTICE: Be careful not to use excessive force while opening the microprocessor socket. Excessive force could damage the socket. |
NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending the pins can permanently damage the microprocessor. |
Figure 6-10. Removing and Installing a Microprocessor
If any of the pins on the microprocessor appear bent, see "Getting Help" for instructions on obtaining technical assistance.
NOTICE: Positioning the microprocessor incorrectly can permanently damage the microprocessor and the server module when you turn on the server module. When placing the microprocessor in the socket, be sure that all of the pins on the microprocessor go into the corresponding holes. Be careful not to bend the pins. |
NOTE: Force is not needed to install the microprocessor in the socket. When the microprocessor is aligned correctly, it should drop into the socket. |
NOTICE: Be careful not to use excessive force while closing the microprocessor socket. Excessive force could damage the socket. |
As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in the System Setup program. A message similar to the following appears:
One 1.26 GHz Processor, Processor Bus: 133 MHz, L2 cache 512 KB Advanced
See "Running the System Diagnostics" for information on running the diagnostics and troubleshooting any problems that may occur.
The system battery is a 3.0-volt (V), coin-cell battery.
CAUTION: Before you perform this procedure, see "Safety FirstFor You and Your System" in "Troubleshooting Your System." |
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide. |
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions. See your System Information Guide for additional information. |
See Figure A-3 to locate the system battery on the server module board.
You can pry the system battery out of its connector using a blunt, nonconductive object such as a plastic screwdriver.
Figure 6-11. Replacing the System Battery
Your system includes up to two hard drives and are located on one side of the server module. The hard drives are secured to the server module using four 6-32 x 0.25 hex-head Phillips screws. The hard drives input power connector is connected to the SCSI PWR connector located on the server module board. The hard drives SCSI data cable is connected to the SCSI connector located on the server module board.
The SCSI controller on the server module board supports integrated mirroring if two SCSI drives are installed.
Follow these guidelines to implement integrated mirroring on your server module:
NOTE: Dell strongly recommends that you use Dell OpenManage Array Manager to enable and configure integrated mirroring. |
For more information on this feature, see the integrated mirroring documentation provided with your system.
Although SCSI drives are installed in essentially the same way as other drives, their configuration requirements are different. To install and configure a SCSI drive, follow the guidelines in the following subsections.
SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends. When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.
Each drive attached to a SCSI controller must have a unique SCSI ID number from 0 to 15.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that drives be attached to the cable in order by ID number. |
SCSI logic requires that termination be enabled for the two drives at opposite ends of the SCSI chain and disabled for all drives in between. For internal SCSI drives, termination is configured automatically. See the documentation provided with any optional SCSI drive you purchase for information on disabling termination.
CAUTION: Before you perform this procedure, see "Safety FirstFor You and Your System" in "Troubleshooting Your System." |
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide. |
NOTICE: If two hard drives are installed and you are removing the hard drive toward the front of the server module, disconnect the SCSI and power cables from the back hard drive first to avoid damaging the SCSI and power cables connected to the front hard drive. |
Figure 6-12. Removing and Installing a Hard Drive
If two hard drives were installed and the integrated mirroring feature was enabled, the server module will automatically reimage the new hard drive when you turn on the server module.
The drive or device from which the system boots is determined by the boot order specified in the System Setup program (see "Using the System Setup Program" in your User's Guide).
