The unique design of your server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory management. Your server
combines:

• Impressive performance using an innovative approach to SMP
Your server supports up to two Pentium III microprocessors. Your server comes

with one microprocessor installed; you can install an additional microprocessor
to enhance performance and provide SMP capability.

• Large data-storage and hot-swap capabilities
All models of the server support up to six hot-swap hard disk drives. This hot-

swap feature enables you to remove and replace hard disk drives without
turning off the server.

• Redundant power capabilities
The standard 250-watt power supply in your server can handle a load of up to

250 watts. By replacing the power backplane with the power backplane option,
you can install a second, optional power supply. This provides a full 500 watts
of power. If the average load on your server is less than 250 watts and a problem
occurs with one of the power supplies, the other power supply can handle the
load (redundant power). If the average load on your server is greater than 250
watts, and you have installed a second power supply, you can install a third,
optional power supply to provide redundancy.

The NON light emitting diode (LED) on the system board is lit when the power
load is 250 watts or greater with two power supplies, or when the power load is
500 watts or greater with three power supplies.

• Large system memory
The memory bus in your server supports up to 4gigabytes (GB) of system

memory. The memory controller provides error correcting code (ECC) support
for up to four industry standard PC133, 3.3 V, 168-pin, 8-byte, registered,
synchronous-dynamic-random access memory (SDRAM) dual inline memory
modules (DIMMs).

4 IBM® xSeries 150 : User’s Reference

• System-management capabilities

Y our server comes with a Netfinity Advanced System Management Processor on
the system board. This processor enables you to manage the functions of the
server locally and remotely. The Netfinity Advanced System Management
Processor also provides system monitoring, event recording, and dial-out alert
capability.

Note: The Netfinity Advanced System Managem e nt Processor is sometimes

referred to as the service processor.

• Integrated network environment support
Your server comes with an Ethernet controller on the system board. This

Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps
networks. The server automatically selects between 10BASE-T and 100BASE-TX.
The controller provides full-duplex (FDX) capability , which allows simultaneous
transmission and reception of data on the Ethernet local area network (LAN).

• Redundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a

failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traf fic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.

• Optional digital linear tape drive
The addition of an optional digital linear tape drive (DLT) allows quick backup

of large amounts of data.

Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
your server; that your server is available when you want to use it; and that should a
failure occur, you can easily diagnose and repair the failu re with mi nimal
inconvenience.

The following is an abbreviated list of the RAS features that your server supports.

• Menu-driven setup, system configuration, RAID configuration, and diagnostic
programs

• Power-on self-test (POST)

• Integrated Netfinity Advanced System Management Processor

• Predictive failure alerts

• Remote system problem-analysis support

• Power and temperature monitoring

• Hot-swap drive bays

Chapter 2. Arranging your workspace

To get the most from your server, arrange both the equipment you use and your work
area to suit your needs and the kind of work you do. Your comfort is of foremost
importance, but light sources, air circulation, and the location of electrical outlets also
can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few guidelines
to help you find a position tha t suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can make a
big difference. The backrest and seat should adjust independently and provide good
support. The seat should have a curved front to relieve pressure on the thighs. Adjust
the seat so that your thighs are parallel to the floor and your feet are either flat on the
floor or on a footrest.

When using the keyboard, keep your for earms parallel to the floor and your wrists in
a neutral, comfortable position. Try to keep a light touch on the keyboard and your
hands and fingers relaxed. You can change the angle of the keyboard for maximum
comfort by adjusting the position of the keyboard feet.

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the
monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 in.), and
position it so you can view it without having to twist your body. Also position other
equipment you use regularly, such as the telephone or a mouse, within easy reach.

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Even reflected light from shiny surfaces can cause
annoying reflections on your monitor screen. Place the monitor at right angles to
windows and other light sources, when possi ble. Red uce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you in stall the
monitor near a window, use curt ains or blinds to block the sunlight. You might have
to adjust the Brightness and Contrast controls on the mon itor as the room lighting
changes throughout the day.

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter
placed over the screen might be helpful. However, these filters might affect the clarity
of the image on the screen; try them only after you have tried all other methods of
reducing glare.

Dust buildup compounds problems that are associated with glare. Remember to clean
your monitor screen periodically using a soft cloth that is moistened with a
nonabrasive liquid glass cleaner.

Air circulation

Your server and monitor produce heat. Your server has one or more fans that pull in
fresh air and force out hot air . The monitor lets hot air escape through vents. Blocking
the air vents can cause overheating, which might result in a malfunction or dama ge.

10 IBM® xSeries 150 : Use r’s Reference

Place the server and monitor so that nothing blocks the air vents; usually, 15 cm (6
inches) of air space is sufficient. Also, make sure that the vented air is not blowing on
someone else.

Electrical outlets and cable lengths

The location of electrical outlets and the length of power cords and cables that connect
to the monitor, printer, and other devices might determine the final placement of your
server.

When arranging your workspace:

• Avoid the use of extension cords. When possible, plug the server power cords
directly into electrical outlets.

• Keep power cords and cables neatly routed away from walkways and other
areas where they might get kicked accidentally.

For more information about power cords, refer to the power cord information in this
on-line publication.
