20 Maintaining and Troubleshooting the Gateway ALR 7300 Server

and dynamic resource allocation for all attached peripherals. Most major operating systems provide USB drivers and should require no special procedures for implementation or use.

•Two 9-pin 16550-compatible serial ports

•One bidirectional ECP/EPP parallel port

•One video port

•One PS/2-style mouse port

•One PS/2-style keyboard port

•One RJ-45 Ethernet connector with two LEDs. The green LED shows that the system is communicating with the network and the yellow LED shows that communication is occurring at 100 Mbps.

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

Depending on the model, the system is equipped with one Intel Pentium® II

Xeon™ processor with 512-KB, 1-MB, or 2-MB ECC L2 cache, integrated into a single edge contact (SEC) cartridge.

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

Processor fan connectors

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.

Important!

Processor slot 1 is the boot processor slot. In a single processor configuration, the processor must be installed in processor slot 1 and a terminator card must be installed in processor slot 2.

Components 21

Important!

The quick hot-swap RAID Cage may or may not be included as a standard part of the server configuration.

Voltage regulator modules

Each processor must have a dedicated voltage regulator module (VRM) which adjusts the voltage supplied to the processor. The VRM for the first processor (CPU 1) is embedded on the system board.

Memory

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

Quick Hot-swap RAID cage

The quick hot-swap cage allows you to configure a reliable RAID subsystem. The quick hot-swap cage consists of a drive cage and all of the necessary hardware to install it in the system. Each cage supports three one-inch high 3.5-inch SCA SCSI drives. For optimum operation, use only approved RAID-ready drives in the RAID Cage. The RAID Cage occupies two standard half-height 5.25-inch drive bays.

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

Hot-swapping is a useful features that allows you to replace a failed hard disk drive without interrupting system operation. In the event of a hot-swappable drive failure, which is part of a RAID 5, the system

22 Maintaining and Troubleshooting the Gateway ALR 7300 Server

continues normal operations. You can replace the failed drive and rebuild its contents on an equivalent replacement drive automatically, without shutting down the system.

Figure 9: RAID Cage

SCSI backplane components

The SCSI backplane connects the SCA-2 LVD SCSI drives to the SCSI RAID controller or the SCSI controllers on the system board. The backplane provides automatic SCSI address setting and allows hot-swapping of SCSI drives. Figure 10 shows the back of the backplane where the drives connect.

Figure 10: The Back of the SCSI Backplane

If the RAID cage is included as part of the server configuration, see the Quick Hot-swap Installation Guide for information on how to configure the quick hot-swap backplane.

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.

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 first processor.

When replacing a processor, order a Pentium II Xeon processor upgrade kit. The kit includes the Pentium II Xeon processor, a heat sink, and a VRM.

It is critical that a heat sink be installed on each Pentium II Xeon 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.

For the latest details on the availability of the upgrade kits, contact one of the sources listed in the Assistance Resources document.

To Replace the Processor

Installing a second 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 adding a processor, order a Pentium II Xeon processor upgrade kit. The kit includes the processor, a heat sink, and aVRM.

It is critical that a heat sink be installed on each Pentium II Xeon processor. The 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.

For the latest details on the availability of the upgrade kits, contact one of the sources listed in the Assistance Resources document.

To Install a Second Processor

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

2.Open the case (“Opening the system” on page 3), observing the static electricity precautions in “Static electricity precautions” on page 2.

3.Remove the lock bar from the processor supports as shown in Figure 11 on page 27.

4.Remove the Terminator Card from the system board (see Figure 14).
