Preface

Intended Audience

This manual is for managers and operators of AlphaServer ES45 systems.

Document Structure

This manual uses a structured documentation design. Topics are organized into
small sections, usually consisting of two facing pages. Most topics begin with an
abstract that provides an overview of the section, followed by an illustration or
example. The facing page contains descriptions, procedures, and syntax
definitions.

This manual has eight chapters.

• Chapter 1, System Overview, gives an overview of the system and

describes the components.

• Chapter 2, Operation, gives basic operating instructions on powering up

and configuring the machine, setting console security, and updating
firmware.

• Chapter 3, Booting and Installing an Operating System, describes

how to boot a supported operating system and how to begin an operating
system installation.

• Chapter 4, Configuring and Installing Components, shows how to

install memory DIMMs, CPUs, PCI cards, and other options.

• Chapter 5, Firmware, describes the SRM firmware, which allows you to

configure and boot the Tru64 UNIX,Linux,orOpenVMS operating system
and verify the configuration of devices. It also provides a reference to the
SRM commands and environment variables.

• Chapter 6, Remote Management, describes the function and operation of

the integrated remote management console.

xvi

• Chapter 7, Troubleshooting, gives basic troubleshooting procedures.

• Chapter 8, Specifications, gives system specifications.

1.6 Operator Control Panel

The control panel provides system controls and status indicators. The
controls are the Power, Halt, and Reset buttons. A 16-character back­lit alphanumeric display indicates system state. The panel has two
LEDs: a green Power OK indicator and an amber Halt indicator.

Control panel display. A one-line, 16-character alphanumeric display that
indicates system status during power-up and testing. During operation, the
control panel is back lit.



Power button. Powers the system on and off.
If a failure occurs that causes the system to shut down, pressing the power

button off and then on clears the shutdown condition and attempts to power
the system back on. Some conditions that prevent the system from power­ing on can be determined by entering the env command from the remote
management console (RMC). The RMC is powered separately from the rest
of the system and can operate as long as AC power is present. (See Chapter

6.)

System Overview 1-11



Power LED (green). Lights when the power button is pressed.



Reset button. A momentary contact switch that restarts the system and
reinitializes the console firmware. Power-up messages are displayed, and
then the console prompt is displayed or the operating system boot messages
are displayed, depending on how the startup sequence has been defined.



Halt LED (amber). Lights when you press the Halt button.



Halt button. Halts the system and returns to the SRM console.
If the Halt button is latched when the system is reset or powered up, the

system halts in the SRM console. Systems that are configured to autoboot
cannot boot until the Halt button is unlatched.

Commands issued from the remote management console (RMC) can be used to
reset, halt, and power the system on or off. For information on RMC, see Chap­ter 6.

RMC Command Function

Power {off, on} Equivalent to pressing the Power button on the system. If

the power button is in the Off position, the RMC Power On
command has no effect.

Halt {in, out} Equivalent to pressing the Halt button on the control panel

to cause a halt (halt in) or releasing it from the latched posi-
tion to de-assert the halt (halt out).

Reset

Equivalent to pressing the Reset button on the control panel.

1.7 System Motherboard

The system motherboard is located on the floor of the system card cage
and has the majority of the logic for the system.

The system motherboard has connectors for the CPUs and memory mother­boards (MMBs) and a connector to the I/O subsystem. Figure 1–6 shows the
location of these modules on the motherboard.

System Overview 1-13

CPU Card

The system can have up to four CPU cards. The CPU cards are installed on the
system board. Each CPU card contains an EV68 microprocessor, a current im­plementation of the Alpha architecture.

The microprocessor is a superscalar CPU with out-of-order execution and specu­lative execution to maximize speed and performance. It contains four integer
execution units and dedicated execution units for floating-point add, multiply,
and divide. It has an instruction cache and a data cache on the chip. Each
cache is a 64 KB, two-way, set-associative, virtually addressed cache that has
64-byte blocks. The data cache is a physically tagged, write-back cache.

Each CPU card has an 8 MB B-cache (backup cache) and a power regulator.
See Chapter 4 for instructions on installing additional CPUs.

Memory Motherboards (MMBs)

Memory options are installed into memory motherboards (MMBs) located on the
system motherboard (see Figure 1–6). There are four MMBs. The MMBs have
either four or eight slots for installing DIMMs.

See Chapter 4 for memory configuration rules and installation instructions.

1.8 I/O Backplane

The ES45 server has three I/O versions: Models 1B, 2B, and 3B.

1.8.1 Model 1B

Model 1B has six PCI slots with four at 66 MHz, two at 33 MHz, and one AGP
4x slot.
