Introduction

The AcerAltos 21000 is a powerful 64-bit quad-processor system loaded with a host of new and innovat i v e features. The system of fers a new standard for flexible productivity ideal for local or wide area networks and multi-user server envir onments.
Intel Pentium II Xeon Processor with the Intel 450NX Chipset
The Pentium II Xeon processor, like its predecessors, the Pentium Pro and Pentium II processors, implements a Dynamic Execution micro-architecture - a unique combination of multiple branch prediction, data f low analysis, and speculative execution. Thi s means that the Pentium II Xeon can deliver higher performance than the Pentium Pro processor while maintaining binary compatibility with all previous Intel Architecture processors.
Also, the Pentium II Xeon processor is avail able in 512K, 1MB, and 2MB L2 cache options with the introduction of the Slot 2 socket. Unlike Sl ot 1 Pentium IIs, which access the L2 at half the pr ocessor speed, the Slot 2 accesses the L2 at f ull processor clock speed. An addition t o the Pentium II Xeon processor is the Int el 450NX chipset, for servers with four or more processors, which supports a 100MHz front-side bus, USB (four ports), a south bridge to the ISA bus, provi des up to 8GB of mem ory support and m ult iple 32- bit and 64-bi t PCI buses.
In addition to meeti ng the mission-critical and fast system response tim e requirements of enterprise serv ers, the AcerAl tos 21000 is fault tolerant and capable of preventing faults from occurring. It also demonstrates graceful performance scalability when the system confi gur ation is expanded.

Dual Ultra2
The system inc ludes a m ai n and m em ory subsystems with four Slot 2 processors and voltage regulators for the processors. The memory subsystem runs in 100 MHz ti mi ng and has a max im um siz e of up to 4GB.
Six PCI and 1 PCI/ISA shared slots are also incorporated for fast expandable I/O capabilities.
There are two LVD SCSI (Ultra-2) channels for high performance storage devi ces and one Narrow SCSI channel f or backup ( i.e., tape drives) or CD-ROM devices.
A high-speed 10/100Mbi t Ethernet controll er and a PCI VGA dev ice are also provided.
For more information about the main board see secti on 3.1.
xvi AcerAltos 21000 System Guide
Server Management
The system comes with the ASM Pro f eature that m onitors voltage stability and CPU temperature, prevents data loss by prompt ECC memory error reporting, maximizes system resources by indicating the PCI bus utilization, and promotes eff i ci ency by m i ni m i zi ng system downtime.
A feature related to ASM Pro is Remote Diagnostic Management (RDM) that permits system diagnosis from a remote site through a modem. RDM facilitates the fixing of detected problems, changing system conf igurations or reboot ing in the event of system fai lure.
Hot-swappable Redundant Power Supply Subsystem
The system comes with a power backplane that holds up to three 430­watt power supply modules. The power subsystem supports a redundant conf iguration such t hat even i f one power supply fail s, the remaining two continue to work t ogether to supply 860-watt power to a full y-confi gured system . You can also replace a faul ty power supply module without opening the system housing or shutting down the system. See section 2.5 for more information.
Hot-swappable Redundant Housing Fan
The system comes with four housing f ans that v entilate the system housing. In the event t hat any one of the fans f ails to operate, you can simpl y replace it without shutti ng down the system. See secti on
2.6 for more information.
Security
The system housing comes with mechanical security locks on the front panel to prevent unauthori z ed ac c ess to the internal c omponents and system use. Also, a microswitch l ocated on the left side of the housing panel warns you of i ntrusion.

2. Flip up both of the pl astic ears of t he Penti um II Xeon processor. This procedure detac hes the pr oc essor from the socket .
3. Carefully lift up the Pentium II Xeon processor and remove it.
3.1.5 Installing and Removing a VRM (Voltage
Regulator Module)
Each Pentium II Xeon processor requires two VRMs (Voltage Regulator Modules), one for t he pr oc essor and another one for the L2 cache. However, two L2 caches share one VRM. If y ou are i nstalling two Pentium II Xeon processor, you need three VRM s: t wo VRMs for each processor and one VRM for both of the L2 cache to share. Refer to section 3.1.2 for the location of the VRM sockets. The following table shows the VRM socket allocation:
VRM Socket Slot 2 Socket
VRM Socket 1 (CN4) CPU 1 VRM Socket 2 (CN11) L2 cache of CPU 1 and 2 VRM Socket 3 (CN1 8 ) CPU 2 VRM Socket 4 (CN2 0 ) CPU 3 VRM Socket 5 (CN23) L2 cache of CPU 3 and 4 VRM Socket 6 (CN2 9 ) CPU 4
3-12 AcerAltos 21000 System Guide
VRM LED
There is one LED indicator for each VRM module. Before system power-on, an LED would l ight up (green) i f a VRM i s required for the processor or the L2 cache. If you see a red li ght af t er power-on, then it m eans that the VRM is bad and that it needs to be replaced.
To install a VRM:
1. Find an empty VRM socket and fli p the lev er bac k .
2. Carefully insert a VRM into the socket. This process will automatically lock the VRM in place.
To remo ve a V RM :
1. Push down both the locking mechanisms.
2. Take out t he V RM .

Chapter 4 BIOS Utility
The BIOS Utility allows you to view your system’s configuration settings.
Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a Run Setup m essage.
The Setup program loads configuration val ues into the bat t ery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM.
If you repeatedly receive Run Set up messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
