Processor subsystem

The system board supports as many as two processors (CPUs). The board provides several additional connectors for supporting components, as described in the following paragraphs.

Processors and processor slots (AQ, AR)

Depending on the model, the system is equipped with one Intel Pentium® II Xeon™ processor with 512-KB, 1 MB, or 2 MB of ECC level-two (L2) cache integrated into a single edge contact (SEC) cartridge. The boot processor (AQ) must be present in all configurations. The application processor (AR) is optional.

The system SMP design supports up to two processors and is Intel MP Specification v1.1 and 1.4 compliant.

Processor fan connectors (AX, BA)

The processor fan connectors provide power for the fans mounted on the processor heatsinks. These fans cool the processors and prevent overheating. Note that not all processor heatsinks have or need fans. If the processor heatsink includes a fan, connect it to the correct fan connector. These connectors are not used in the standard configurations.

22 Maintaining and Troubleshooting the Gateway ALR 8300 Server

Voltage regulator modules (AY, AZ)

Each processor must have a dedicated voltage regulator module (VRM) that adjusts the voltage supplied to the processor. The VRM for the boot processor (CPU 1) is integrated into the system board.

Memory (AS, AT, AU, AV)

The system comes standard with 64 MB of error checking and correcting (ECC) RAM. System RAM is expandable up to 2 GB using 100 MHz ECC PC100-compliant 100 MHz 72-bit synchronous DRAM (SDRAM) DIMMs (4 DIMM sockets). System memory is PC 100 compliant.

The RAID backplane

The RAID backplane allows you to easily configure a reliable RAID subsystem. The RAID bay supports six 1-inch or 1.6-inch high 3.5-inch drives. For optimum operation, only approved, RAID-ready drives should be used with the RAID backplane.

Drives are mounted on a rail system, which provides quick and easy installation and hot-swapping capability. A fully functional RAID subsystem is controlled by a RAID Caching Controller.

Hot-swapping is a useful feature that allows you to replace a failed hard disk drive without interrupting system operation. In the event of a hot-swappable drive failure, in which the drive is part of a RAID 5 array, the system continues normal operation. The failed drive can be replaced and its contents rebuilt automatically on an equivalent replacement drive without interrupting the operation of the system.

To configure the backplane, refer to the RAID Cage Configuration Guide.

The system board provides an embedded voltage regulator module (VRM) to provide the correct voltage for the first processor. You do not need to install an additional or replacement VRM. If a VRM was included in your processor upgrade kit, do not use it.

Replacing the processor

The system is compatible with Intel Pentium® II Xeon™ processors.

You can either upgrade the existing Pentium II Xeon processor or install a second processor of the same speed as the original processor.

When replacing a processor, order a Pentium II Xeon processor upgrade kit. The kit includes the processor, a heat sink, and a disposable electrostatic discharge (ESD) wrist strap. For the latest details on the availability of the upgrade kits, contact one of the sources listed in the Assistance Resources document.

It is critical that a heat sink be installed on each processor. The Pentium II Xeon processor overheats and fails if it is not cooled sufficiently. The heat sink provided with the processor on the system provides all necessary cooling for the processor, as long as the system covers are on.

To Replace the Processor

1.Turn off the system and disconnect the power cord.

2.Open the case, observing the ESD precautions in “Static electricity precautions” on page 2.

4.Remove the two screws that secure the processor cartridge in the supports and remove the lock bar.

5.Lift the processor cartridge straight up and away from the system board. See Figure 10.

Important!

If the error message “update table not found for CPUxx, Stepping xxxx” displays at boot up, run the MULOADER utility located on the disk included with your processor kit. This message may occur under the following conditions: When a new processor has been added that does not include the stepping information in the table. When the BIOS is flashed, it may remove the stepping information form the table which will cause the error message to appear.
