may result in an explosion. Dispose of lithium batteries as required by local ordinance or as normal waste if no local ordinance exists.

Warning: The detachable power supply cords are intended to serve as the disconnect

devices.

Warning: This equipment has a 3-wire, grounded power cords. To prevent electrical

hazards, do not remove or defeat the ground prong on the power cords. Replace a power cord if it gets damaged. Contact your dealer for an exact replacement.

Warning: The DC push-button on/off switch on the front panel does not turn off the

system AC power. Also, +5vdc is present on the system board whenever the AC power cords are connected between the system and an AC outlet. Before doing the procedures in this manual, make sure that your system is powered off and unplug the AC power cords from the back of the chassis. Failure to disconnect power before opening your system can result in personal injury and equipment damage.

In the U.S.A. and Canada, the power cord must be a UL-listed detachable power cord (in

Canada, CSA-certified), type ST or SJT, 16 AWG, 3-conductor, provided with a molded-on

NEMA type 5-15 P plug cap at one end and a molded-on cord connector body at the other

end. The cord length must not exceed 9 feet (2.7 meters).

Outside the U.S.A. and Canada, the plug must be rated for 250 VAC, 10 amp minimum,

and must display an international agency approval marking. The cord must be suitable for

use in the end-user country. Consult your dealer or the local electrical authorities if you are

unsure of the type of power cord to use in your country. The voltage change occurs via a

switch in the power supply.

Warning: Under no circumstances should the user attempt to disassemble the power

supply. The power supply has no user-replaceable parts. Inside the power supply are hazardous voltages that can cause serious personal injury. A defective power supply must be returned to your dealer.

System Features

Overview

This server is well suited for Symmetric Multiprocessing (SMP) and Enterprise class network server environments and is a highly reliable, high-powered, fault-tolerant, high-capacity multiprocessing system based on the Intel Pentium III® processor family. It is a fully redundant system with on-line serviceability and hot plug replacement of all major subsystems and a solid performer offering the latest technology. The server system is conveniently housed and available as a tower-based system, including housing for the tape drive module (see Figure 1-1) or as a rack-mount system, without housing for the tape drive module (see Figure 1-2) in a relatively small form factor of 8U (fits into a standard EIA 19-inch rack assembly.)

The combination of mirrored computing performance, memory capacity, and integrated I/O provides a high performance environment for many applications including network servers. The server system is designed for use in applications where fault-tolerant, advanced technology, high performance, and high levels of reliability and compatibility are expected.

1-2 System Overview

Figure 1-1. Tower-Based System

Figure 1-2. Rack-Mount System

This server system is designed for full redundancy and hot plug replacement of all major subsystems. The system modules that can be replaced are identified as Customer Replaceable Units (CRUs) of which most are redundant and hot pluggable. To this end, the server includes or has the option to include the following:

Two self-contained power supplies that provide redundant power (i.e., the system

will continue to operate with a single power supply failure) and are hot swappable. The two power supplies are easily installed or removed from the back of the chassis without turning the system power off.

Cooling system redundancy where the system will continue to operate in the event of

a fan failure and the redundant fans will switch to maximum operating speed.

SCSI hard disk drive bays accessible from the front of the chassis.

Hot-swap SCSI disk drive backplane; a failed drive can be removed and replaced

with a new drive without system power being turned off.

High degree of SCSI disk fault tolerance and advanced disk array management

features.

Video Graphics Array (VGA) controller with 4 MB of video memory (occupies one

PCI slot per PCI module).

SCSI disk adapter providing dual channel Ultra 160 SCSI interfaces for the hot swap

hard disk drives.

Embedded single channel enhanced IDE adapter providing interface for peripheral

devices (CD-ROM and super floppy disk drive).

Integrated onboard Network Interface Controller (NIC), an Intel 82559 PCI LAN

adapter for 10 or 100 Mbps Ethernet networks with a RJ-45 Ethernet connector.

Storage module that holds up to six hot-swap SCSI hard disk drives (three logical

disks).

SCSI backpanel is Ultra2 capable.

Integrated dual Universal Serial Bus (USB) ports that include support for the

keyboard and mouse.

Hardware monitors (temperature, fans, and voltage) and software monitors to

indicate failures.

Hardware monitors (temperature and voltage) and software monitors to indicate

failures.

Easy access to all parts for service.

System Overview 1-3

As application requirements increase, you can expand your server system with additional processors, additional memory, add-in boards and peripheral devices.

Your server system features the following major components:

Up to two high-performance 800 MHz Pentium III processors in a CPU module.

Up to 2 GB of Synchronous Dynamic Random-Access (SDRAM) system memory in

a CPU module.

Four PCI expansion slots, which support 32 bit PCI adapter cards in a PCI module.

Fault-Tolerant Hardware

The hardware architecture of the system provides fault tolerance transparency. If a hardware component fails, the application program continues processing and is never aware that a failure occurred.

To provide system redundancy this system uses dual hardware technology. That means that all major components are mirrored within a single hardware chassis. Group #1 is on the left-hand side of the chassis and Group #2 is on the right-hand side of the chassis, as viewed from the front of the chassis, see Figure 1-3. There are two CPU modules and each CPU module is operating in lockstep (performing the same instructions at the same time) with the other as a single system. Thus, if a failure occurs in one CPU module the other CPU module will continue to operate with no interruption, no loss of data, and system performance is not affected. Note that the PCI module, PCI adapters, and power supplies are also paired for system redundancy.

Power Supplies

The server has two standard 450-Watt power supplies. Each supply has autoranging input 50/60 Hz and automatically switches between the following input voltage ranges:

100-127 VAC at 50/60 Hz; 7.6 A maximum current

200-240 VAC at 50/60 Hz; 3.8 A maximum current

CPU Modules

The server has two CPU modules that provide Dual Modular Redundancy (DMR). The CPU modules are numbered 1 and 2, left to right as seen from the front of the system. Each CPU module has two status indicators that are listed along with a description of each in Table 1-3. Table 1-8 summarizes the features of a CPU module.

Feature Description

Upgradable multiple processor slots

Table 1-8. Features of the CPU Module

Two processor sockets are available on the CPU board for one or two processors.

Upgradable memory

SMP Supports two-way Symmetric Multiprocessing (SMP) when two processors

Fan Two integrated fans that provide cooling for both the CPU module and hard

The system runs identical applications in both CPU modules in lockstep. Thus, if one CPU module fails, the second CPU module takes over the processing without any interruption to the current application running on the system. Note that this type of failure is transparent to the user.

In simplex mode the system is operating with only one CPU module and one PCI module. Thus, the failure of one CPU module or one PCI module causes the whole system to fail. A fault-tolerant system should not run in the simplex mode for any longer than necessary for upgrading or repair.

Storage Bays

The server has a storage area containing six storage bays that support six hard disk drives (three logical disks). The hard disk drives are CRUs, hot pluggable, and redundant. The disk slots are physically numbered 1 – 6, left to right as seen from the front of the system. The disk drives SCSI ID numbers are 0, 1, 2 for each group of logical disk drives and the first mirrored pairs are physical drives 1 and 4 that contain the boot software, as shown below.

Four DIMM sockets on the CPU board. Can contain a minimum of 256 MB up to a maximum of 2 GB of Synchronous Dynamic Random-Access (SDRAM) system memory.
