Upgrading the system memory

This section includes instructions for removing and installing a
memory module.

The Server Boards Altos G520 each provides four DDR266 / DDR333
DIMM sites in two DIMM banks. The maximum memory capacity is 8GB
for either DDR266 or DDR333 memory. Memory DIMM technologies
supported are: 128MB, 256MB, 512MB, 1 GB and 2 GB.

The minimum memory configuration is one DIMM, installed in DIMM
socket 1B (the socket farthest from the processors). However, for
optimum performance and dual-channel interleave operation, a
minimum of two DIMMs should be installed. DIMMs on channel A are
paired with DIMMs on channel B to configure 2-way interleaving.

Both DIMMS in Bank 1 (DIMM1B and DIMM1A) must be populated
before any DIMMs are installed in Bank 2 (DIMM2B and DIMM2A).
Bank 2 must be populated in pairs.

Both DIMMs in a bank must be identical (same manufacturer, CAS
latency, number of rows, columns and devices, timing parameters etc.).
Although DIMMs within a bank must be identical, the BIOS supports
various DIMM sizes and configurations allowing the banks of memory
to be different.

59

Note: Dual-channel memory requires symmetrical memory
modules using the same density (e.g. 256MB,512MB), bus width
(e.g. x8 ,x16) and granule technology (e.g. 256M-bit, 512M-bit)

The mixing of DDR266 and DDR333 memory is supported on the Server
Boards Altos G520. However, when mixing DIMM types, DDR333 will
be treated as DDR266.

Warning! Functionality issues may be encountered if mixed
memory types are installed on the same server board. DIMM
modules of identical type, banking and stacking technology, and
vendor should be installed in the Altos G520.

60

3 Upgrading the system

3 Upgrading the system

Installing a redundant power supply module

The Altos G520 server power subsystem consists of two hot-swappable
power supply module bays that accept standard 610-watt power
supply modules. The system comes bundled with only a single power
supply module leaving one power supply module bay empty. You have
the option to purchase an extra power supply module to provide your
system with redundant power source. This power configuration
enables a fully-configured system to continue running even if one
power supply module fails.

Note: The redundant power source feature is only applicable to
the Altos G520 model.

WARNING! To reduce the risk of personal injury or
damage to the equipment, the installation of power
supply modules should be referred to individuals who are
qualified to service server systems and are trained to deal
with equipment capable of generating hazardous energy
levels.

WARNING! To reduce the risk of personal injury from
hot surfaces, observe the thermal labels on each power
supply module. You can also consider wearing protective
gloves.

WARNING! To reduce the risk of personal injury from

setup

This chapter gives information about the
system BIOS and discusses how to configure
the system by changing the settings of the
BIOS parameters.

71

BIOS setup

BIOS setup is a hardware configuration program built into your
system's Basic Input/Output System (BIOS). Since most systems are
already properly configured and optimized, there is no need to run this
utility. You will need to run this utility under the following conditions:

• When changing the system configuration

• When a configuration error is detected by the system and you are
prompted ("Run Setup" message) to make changes to the BIOS
setup

Note: If you repeatedly receive Run Setup messages, the battery

may be bad. In this case, the system cannot retain configuration
values in CMOS. Ask a qualified technician for assistance.

• When redefining the communication ports to prevent any conflicts

• When making changes to the Power Management configuration

• When changing the password or making other changes to the
security setup

BIOS setup loads the configuration values in a battery-backed
nonvolatile memory called CMOS RAM. This memory area is not part
of the system RAM which allows configuration data to be retained
when power is turned off.

Before you run BIOS setup, make sure that you have saved all open
files. The system reboots immediately after you close the setup.

72
