Caution!

Prevent electrostatic damage to your system by following static electricity precautions every time you open your computer case

Static electricity precautions

Static electricity can permanently damage electronic components in your computer. When opening your computer case, always perform the following procedure:

1.Wear a grounding wrist strap (available at most electronics stores).

2.Turn off the system power.

3.Touch the back of the power supply case to discharge any static electricity.

4.Unplug all power cords from AC outlets.

5.Open the computer case.

Follow these precautions to avoid electrostatic damage to your system components:

Avoid static-causing surfaces, such as plastic and styrofoam, in your work area.

Remove the parts from their antistatic bags only when you are ready to use them. Do not lay parts on the outside of antistatic bags since only the inside of the bag provides antistatic protection.

Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots.

Never slide cards or other parts over any surface.

22 Maintaining and Troubleshooting the Gateway ALR 7200 Server

One RJ-45 Ethernet connector with two LED indicators. The green LED indicates a communication link has been established with the network and the yellow indicator shows that the 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.

CPUs and CPU slots

Depending on the model, the system is equipped with one Intel Pentium® II processor with 512-KB ECC L2 cache, integrated into a Single Edge Contact (SEC) cartridge.

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

CPU fan connectors

The CPU 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 heatsink have or need fans. If the processor heatsink includes a fan, connect it to the correct fan connector.

Voltage regulator modules

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

Memory

The system comes standard with 64-MB of Error Checking and Correcting (ECC) RAM. System RAM is expandable up to 1-GB using ECC 60-ns 72-bit synchronous DRAM (SDRAM) DIMMs (4 DIMM sockets).

Components 23

Important!

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

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 (Figure 9). 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 continues normal operations. You can replace the failed drive and rebuild its contents on an equivalent replacement drive automatically, without shutting down the system.

Replacing the processor

The system is compatible with Intel Pentium® II processors.

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

When replacing a processor, order a Pentium II processor upgrade kit. The kit includes the Pentium II processor, a heat sink, and a disposable electrostatic discharge (static electricity) wrist strap.

It is critical that a heat sink be installed on each Pentium II processor. The Pentium II processor overheats and fails if it is not cooled sufficiently. The heat sink provided with the Pentium II 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

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.Wearing an anti-static wristband grounded to the system chassis, remove the lock bar from the processor slot by removing the two screws that secure it (see Figure 11).

4.Lift the cartridge up and away from the system board.

5.Place the processor cartridge that you removed in a safe place.

6.Remove the replacement processor cartridge from its protective wrapping and place it in the cartridge supports for the slot 1 connector.

7.Slide the cartridge all of the way down until it is firmly seated.
