Preparing to Install Your Server
2
Before you install the server in a rack, you should carefully consider the placement of the unit
in its rack and several factors in the infrastructure that will keep the server operating efficiently.
Guidelines for Server Installation
To ensure safe and smooth operation of your server, it’s essential that you plan for proper
location of the server in its rack, adequate power to the components in the rack, and the
appropriate operating environment for the rack.
As you plan for server installation, follow these guidelines to ensure that the server and its
environment are safely and appropriately positioned for efficient operation and service.
Choose the Server’s Position in a Rack
When determining the location for the server in a rack, be sure to allow adequate space for
airflow and servicing from both the front and back.
m
Air to cool the server flows from front to back. Do not cover the front or back of the
server or any of the openings in the server’s front and back panels and case.
Do not block
the air flowing
through the server.
19
m
The server slides out of the rack from the front. Be sure to leave a minimum of 36 inches
clear in front of the server to allow room to open and service it.
m
To provide access to the server’s back panel and cables, leave at least 24 inches clear
behind the server.
m
If you are installing multiple servers or other components in the rack, place the server so
that you can easily open and service it. For example, in a multiple-component installation,
the heaviest items—such as an uninterruptible power supply—are usually placed at or
near the bottom of a rack; servers are often located near the middle of the rack.
m
For a rack with multiple components, you may want to prepare a list of all equipment in
the rack and the requirements for each unit. Such a list should include the following
information:
Component
Server 1
Server 2
Component 3
Electrical Power
Power
needed
Clear area
front/back
Height
in rack
Temperature
range
Other
If you plan to install the server in a rack that contains other components, be sure that the
circuitry and power connections are sufficient for the combined power needs of all
components. To plan for safe and adequate power to the server, follow these guidelines:
m
Check the documentation for all components in the rack to determine their power
requirements. Also determine that the available power supply for the rack is sufficient for
the planned components.
m
If you need assistance in determining the power needs of the components in the rack,
consult an electrical expert who is familiar with your facility.
Important
When planning for electrical power, make sure you have more power than
specified for all components. Also make certain that the power load is distributed evenly
among circuits to the rack’s location. Consult an electrician or other expert if you need
assistance with planning for the power needs of your components.
m
Make sure that the power connections for the server and all other components are
grounded (according to local and national standards). Consult an electrician if you need
assistance with grounding.
m
See Appendix A, “Specifications,” for more information about electrical power
requirements for the server.
20
Chapter 2
Operating Environment
The operating environment for the server’s rack must meet certain requirements:
m Verify that the temperature range of the rack’s location is within the limits established for
the server and all other components.
m Make certain that the rack’s location has adequate ventilation to maintain the necessary
temperature range. This is particularly important for a rack that is enclosed in a cabinet.
m If multiple components are installed in the rack, consider additional cooling to assure
efficient operation of the servers and other equipment.
Rack Stability
The rack must be stable and strong enough to hold the components installed.
m Check the documentation for the rack to make certain that it can carry the load of
components.
m If you are using a two-post (telco) rack, verify that the rack is securely fastened to the
building’s structure at the top and bottom.
m Make certain that all components are secured in the rack.
m When working with components in the rack, never extend more than one at a time.
Considerations for Cables
For optimal efficiency in server operation and maintenance, follow these guidelines for
handling cables connected to the server and other components in a rack.
m Plan to install the cable-management arm supplied with the server. If you don’t install this
device, you must disconnect all cables from the server’s back panel before opening the
server in the rack.
m Arrange all component cables so that they do not interfere with access to the rack. Ideally
each component should have a cable-management option in place so that anyone
servicing units in the rack can readily determine where each cable is connected.
m To ensure full signal strength for Ethernet, serial, and other connections, make sure cables
do not exceed established length limits.
Preparing to Install Your Server
21
Security
Whatever the location of the server and rack, it should be secure.
m Determine that the rack’s location is secure and that only authorized staff members or
technicians can gain access to this site.
m If using a server cabinet that is not stored in a secure room, be sure that the cabinet has
adequate locking and that access to it is limited to authorized staff.
m Develop a plan for distributing and controlling keys to the server environment and access
codes that will allow others to manage servers over the network. Keep the plan updated
with names of key staff and relevant emergency information and procedures.
m Store a copy of essential server access information in a safe location away from the
server site.

3 Installing Your Server in a Rack
Xserve is specifically designed for rack mounting. It is not designed for use as a desktop
machine.
Warning Do not place a monitor on the server or use the top of the server as a shelf in
the rack. Any weight on the server’s enclosure could damage the components inside.
You can install the server in several types of racks, including
m open four-post rack, 19 inches wide and 29–36 inches deep
m cabinet with four-post rack inside, 19 inches wide and 29–36 inches deep
m two-post (telecommunications, or “telco”) rack, 19 inches wide
The server is 1.75 inches (1U) high.
Important Any rack used for Xserve should meet the specifications of the American
National Standards Institute (ANSI)/Electronic Industries Association (EIA) standard
ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and Deutsche
Industrie Norm (DIN) 41494. See the documentation for the rack to determine whether
it is compatible with these standards.
The brackets and screws necessary to attach the server to any of these racks are included
with your server. You need to supply medium-sized and very small Phillips screwdrivers for
the installation.
23
Installing the Server
As noted previously, you can install the server in a four-post or a two-post rack. Instructions
for both procedures are given below. Preparations for installing are the same, whichever type
of rack you use.
Important Check the documentation for your rack for any special requirements.
Get Ready to Install
Before beginning work with the server and rack, make the following preparations.
m If possible, arrange to work with another person as you prepare the server and install it in
a rack.
m Assemble the tools, brackets, and connectors you’ll need for the installation. (All except
the screwdrivers are provided with the server.)
m A medium-sized Phillips screwdriver. If you have a power screwdriver, use it.
m A very small Phillips screwdriver (needed for a four-post rack if you are attaching the
cable-management arm).
m For a four-post rack, you’ll use two small brackets (each has two rivets), two long
U-shaped braces, and eight mounting screws. Also get the cable-management arm and
the two screws to attach it to the server.
m For a two-post rack, you’ll use two L-shaped brackets and eight screws.
Note: Two sets of screws are provided with the server. One set (English) is 10/32 inches
in diameter; the other set is size M5 metric and fit racks with metric holes. Check the
documentation for your rack and use the appropriate set of screws; most racks use one
of the two sizes. If screws are provided with your rack, you can use those as well.
m To measure and mark the position of the server in the rack, you may want to use a
straightedge, such as a yardstick. You’ll also need a pen or pencil and some masking tape
or similar tape.
m Clear a table, cart, or other flat surface near the rack. You’ll need to put the server on it
temporarily during installation, and you can use it to lay out the brackets and screws you’ll
use to attach the server to the rack.
Determine the Position for the Server in the Rack
Review the guidelines for positioning the server in the rack. Then follow these steps to
measure and mark its specific location.
1 Determine the exact position where you want to attach the server and mark it on one side of
the rack.
24 Chapter 3
Some racks have marks at regular intervals (such as 1U) to aid in locating a server; others
may provide a template to help place the server in the rack. If your rack does not have such
aids, measure or count holes from an established point.
Identify the
appropriate holes
in all mounting posts
before you install the
server so that it is
mounted level.
The distance between holes may vary somewhat on racks made by different manufacturers.
2 Use a straightedge to mark the same spot on the other side of the rack.
You can put a pencil mark or a piece of tape on each side of the rack to mark the correct spot.
For a four-post rack, measure and mark the posts at the front and back.
3 To verify that the position is correct, measure 1.75 inches (the server’s height) down from
the hole you’ve marked on the rack.
You measure downward because you’ll attach the cover of the server’s enclosure to the rack,
then slide the server into it.
Prepare the Server for Installation
If possible, work with another person as you prepare and install the server in a rack.
Follow these steps to prepare the server hardware for installation.
1 Unpack the server from its box and place it on the table
Follow the instructions in the booklet Quick Start for Xserve to unpack the server.
2 At the back of the server, write down the serial number from the server’s back panel.
You will need the server’s serial number to log in when you first set up the server software.
Installing Your Server in a Rack 25
3 Remove the protective faceplate from the server’s front panel by unscrewing the
thumbscrews at each side of the faceplate and lifting it off.
Set the thumbscrews aside.
Protective faceplate
Remove the four thumbscrews that hold the protective faceplate
in place, and remove the faceplate by lifting it straight up.
4 Loosen the two thumbscrews (one on each side) at the front of the server’s enclosure.
With the server resting on a flat, clean,
and stable surface, unscrew the two
thumbscrews on the front panel.
These thumbscrews are “captive” and do not separate from the enclosure.
26 Chapter 3
5 Remove the cover of the server’s enclosure by sliding it toward the back of the unit.
Hold the front thumbscrews to keep the main part of the server in place as you slide the
cover toward the back.
With the
server resting
on a flat, clean,
and stable surface,
slide the cover
completely to the
rear. Press these
two latches to
release the cover
from the server
and remove it.
6 When the cover is almost off, press the yellow release latches at the sides of the server’s
interior to release the cover, then take the cover off.
When you’ve removed the cover, set it aside.
Installing Your Server in a Rack 27
7 If necessary, install any optional internal components, such as additional memory or a PCI
card, in the server. Follow the appropriate instructions in Chapter 5, “Installing or Replacing
Server Components,” on page 49.
PCI card slots (2) PCI/AGP card slot
RAM slots (4)
8 If necessary, install any additional Apple Drive Modules in the front panel of the server.
Follow the instructions in “Installing or Replacing an Apple Drive Module” on page 50.
Drive module bay 1 Drive module bay 2 Drive module bay 3 Drive module bay 4
28 Chapter 3
Note: When installing a drive module for the first time, remove the blank drive module and
save it for possible future use. This unit is necessary for appropriate cooling of the server in a
drive bay that has no drive module in it.
When you’ve installed optional items, you’re ready to connect the server to the rack. If you
have a four-post rack or cabinet, proceed to the next section, “Install the Server in a Four-Post
Rack or Cabinet” on page 29. If you have a two-post rack, go to “Install the Server in a TwoPost (Telco) Rack” on page 37.
Install the Server in a Four-Post Rack or Cabinet
A four-post rack can be open or enclosed in a cabinet. Examples of both racks are shown
below. You follow the same steps to attach the server to either of these racks. For a cabinet,
however, you may have to remove the door before installing the server.
Important Be sure to check the documentation for your rack for any specific mounting
instructions.
Four-post cabinet rack
Four-post open rack
Installing Your Server in a Rack 29
Once you’ve marked the exact position for the server on the rack, you’re ready to attach the
server. Here is an overview of the procedure.
m Connect the cover of the server to the front of the rack.
m Assemble the rear mounting hardware.
m Connect the rear mounting hardware to the server enclosure.
m In a four-post rack, install the cable-management arm.
m Slide the server into the cover and secure it.
Follow these steps to attach the server to the rack.
1 Keep the cover of the enclosure level and support it from the center as you slide it into the
rack at the desired position.
Important Work with someone else to make sure the cover is supported and square to the
rack. The cover must be installed level to avoid changing its shape before the screws are
inserted to hold it in place.
Have someone support the
cover in the center while you
attach it to the rack.
30 Chapter 3
2 Screw the flanges at the front of the cover to the front rails of the rack
Be careful not to overtighten the flange screws. Doing so could change the shape of the
cover slightly and make it difficult to slide the server into the cover.
Attach the cover to the two
front rack mounting posts using
four of the screws provided.
Some racks have prethreaded holes and some have square holes that take clips with attached
nuts. You may need to insert a clip (not provided with the server) into the appropriate hole
before attaching the screw.
Some racks have
pre-threaded holes.
Other racks use various
types of removable,
captive nuts to secure
equipment.
Installing Your Server in a Rack 31
3 At the back of the server, position the small bracket inside the server’s cover so that the head
T
of one rivet is facing the side of the cover.
Note: Start on the left side of the server (when facing the back). This makes installing the
cable-management arm more efficient.
4 Push the rivet head through the hole that’s near the back on the side of the cover.
Install the brackets on
the inside of the top cover.
he forward rivet on each bracket
must pass through the hole in the cover.
Each bracket must be
installed with the rivets
oriented low on the bracket.
The head of the rivet protrudes through the cover.
5 Position the long, U-shaped brace on the outside of the server’s cover, so that the curved end
is near the protruding rivet. The indented lip at the curved end of the brace should face the
rivet head.
6 Slide the lip at the end of the brace over both rivets on the small bracket and continue to
slide the brace forward a few inches.
Slide the brace
toward the front of the cover.
Make sure that both rivets
on the bracket have engaged
the slot in the brace.
Make sure the brace is on the outside of the cover and that both rivets are captured in the
center opening of the brace.
32 Chapter 3
7 Slide the brace forward or backward so that the flat end of the brace is flush with the back
rail of the rack and screw the brace’s flange to the rail.
Note: If you are installing the cable-management arm and your server is the same depth as
your rack (or within an inch of it), only attach the brace to the rail on the left side of the
server (as you face the back panel). You attach the cable-management arm along with the
brace at the right rear of the server.
Attach the cover to the
two rear rack mounting
posts using four of the
screws provided.
8 Attach the second bracket and brace, as described in steps 3 through 7.
Note: If your rack is deeper than the server, the braces and brackets extend beyond the
server’s back panel to the rack’s rails.
Install the Cable-Management Arm
Xserve has a cable-management arm that allows you to open the server without
disconnecting cables. In addition, this device supports the cables and relieves strain on the
server’s back-panel connectors.
Important To open the server with the cables attached, you must install and use the cable-
management arm.
If your rack is the same depth as the server (or an inch or so deeper), you attach the cablemanagement arm to one rear post of the rack. If your rack is several inches deeper than the
server, you attach the cable-management arm to one of the braces that supports the back of
the server.
The steps that follow explain how to install the cable-management arm either to the rack or
to the brace.
Installing Your Server in a Rack 33
Attach the Cable-Management Arm to the Rack
1 If the rear rails of your rack are flush with the server’s back panel or within an inch of it,
position the cable-management arm so that the short side is closer to the server’s back panel
and the holes on the long side align with the holes on the brace on the right side.
Place the cable-management arm over the
U-shaped brace, and secure both to the
rack with two of the screws provided.
2 Thread the hook-and-loop straps through the holes in the cable-management arm.
If the straps are already attached, skip this step.
3 Attach the long side of the folding arm to the rear rail, using two of the mounting screws
provided with the server.
The cable-management arm attaches on top of the right brace. The mounting screws hold
both in place.
See “Connect Cables to the Server” on page 40 for details on connecting cables and using the
cable-management arm.
Attach the Cable-Management Arm to the Support Brace
If the rear rails of your rack are more than an inch away from the server’s back panel, you
need to attach the cable-management arm to the support brace at the side of the server
(not to the rear rail). Otherwise the arm will not extend properly when you open the server
in the rack.
1 Use a very small Phillips screwdriver to disconnect the small clamp that wraps around the
long end of the cable-management arm (next to the two oval holes).
You’ll use this clamp and screw to attach the arm to the brace.
34 Chapter 3
2 Hold the cable-management arm with the long end closer to you and fold the hinged section
of the long end away from you.
The hinged section is the part from which you removed the clamp and screw. This section
should be perpendicular to the main part of the arm, with the oval holes furthest from you.
Mount the cable-management arm as close to the back of
the server as possible. Rotate the mounting plate on the arm
so that it lies against the inside of the U-shaped bracket. The
U-shaped bracket should be sandwiched between the arm
and the small clamp. Secure the clamp with the screw that
held it stored on the arm.

1 At the front of the rack, lift the server to the level where the enclosure’s cover is installed and
slide the server into the cover.
Insert the server into the cover
and slide it all the way back.
2 Secure the server in the rack by tightening the thumbscrews on the front.
Tighten the two thumbscrews
to secure the server in the rack.
To secure the drive modules in the
server, use the enclosure key to lock
them in place.
3 To further secure the server and prevent removal of the drive modules, use the enclosure key
(supplied with the server) to fasten the security lock on the front panel. (See the illustration
above.)
36 Chapter 3
4 If you’ve installed the server in a cabinet, replace and close the cabinet door.
Once the server is secured in the rack or cabinet, you can attach cables for the server’s
connections.
See “Connect Cables to the Server” on page 40 for details of connecting cables and using the
cable-management arm.
Install the Server in a Two-Post (Telco) Rack
The server attaches to a two-post rack at the center of the enclosure, so that the front and
back of the server extend beyond the rack.
Important Before installing the server in a two-post rack, make certain that the rack is
securely fastened to the floor. Also check the rack’s documentation for any specific
installation instructions.
Follow these steps to install the server in a two-post rack. (These instructions assume that
you have previously taken the cover off the server; see “Prepare the Server for Installation”
on page 25 for details.)
Installing Your Server in a Rack 37
1 Attach the small L-shaped brackets to the sides of the server enclosure’s cover with four of
the screws provided.
Attach the two telco mounting brackets to the server’s cover
using the four screws provided.
Orient the bracket so that the screws are at the top. Attach the brackets to holes that are
about one-third of the way back from the front panel.
2 Position the cover in the rack at the desired location and screw the flange of the L-shaped
bracket to the front of the rack on each side.
Important Be sure to work with another person for this part of the installation. The cover
should be held level to avoid changing its shape before the screws are inserted to hold it
in place.
Attach the cover to
the telco rack mounting
posts using four of the
screws provided.
Be careful not to overtighten the flange screws. Doing so could change the shape of the
cover slightly and make it difficult to slide the server into the cover.
38 Chapter 3
3 Lift the server to the level where the cover is installed and slide the server into the cover.
Insert the server into the cover and slide it all the way back.
4 Secure the server in the rack by tightening the thumbscrews on the front.

illustration above.)
Note: You cannot use the cable-management arm on an Xserve system that is installed in a
two-post rack.
Installing Your Server in a Rack 39
Connect Cables to the Server
Once the server is secured in the rack, you can connect the cables and power cord to its back
and front panels.
Important If you use the cable-management arm, your cables must be approximately 3 feet
longer than the distance between the server and its peripheral devices. This extra length may
not be feasible for some cables, such as SCSI cables. In this instance, you can bypass the
cable-management arm with a shorter cable. But you must disconnect that cable when you
open the server.
Follow these steps to connect cables for network connections and peripheral devices.
1 Assemble the cables and devices you will connect to the server’s back panel. Make certain
that each cable has the proper connector and that it is designed for use in a high-capacity
server. (Check the documentation for each peripheral device or cable to determine that it
can be used with the server.)
2 Attach an identifying label to each cable you are connecting.
The labels allow you to locate a specific cable quickly and avoid errors when disconnecting
cables.
3 Beginning at one side of the server’s back panel, connect each cable to its respective port.
Do not attach the power cord yet.

4 Arrange all the cables on the back panel in the cable-management arm and secure them with
the straps provided with the cable-management arm.
The cable-management arm can only be used with a four-post rack or cabinet.
If you are not using the cable-management arm, skip this procedure. It’s a good idea to
group the cables and arrange them so that they don’t cause any hazard and are easy to
handle should you need to detach them when opening the server.
Gather all the cables attached to the server
except the power cord, and attach them to
the cable-management arm. Use the
hook-and-loop fastener straps
to secure the cables to
the arm.
Make sure you lay the cables against
the full length of the cable-management
arm to assure unobstructed extension.
a Group the cables together loosely and “fold” them to the right side of the back panel,
until they are near the short (inner) end of the cable-management arm.
b Reverse the direction of the cables and lay them along the edge of the cable-management
arm closest to the server’s back panel.
c Attach the cables to the arm with the straps provided.
Wrap the cables so that the sides of facing straps do not stick to each other.
d Reverse the direction of the cables again and lay them along the edge of the cable-
management arm furthest from the back panel.
e Attach the cables to the arm with the straps provided.
5 Connect the power cord to the back panel.
Installing Your Server in a Rack 41
6 Attach the power cord’s retainer clip to the back panel to keep the power cord in place when
you open the server.
The ends of the clip fit into the small openings at either side of the power socket. Be sure
that the rounded part of the clip goes under the cord, so that the cord is supported.
Attach the power cord
retainer clip to the two
loops on the back of
the server. Snap the
cord into the clip so that
it cradles the cord.
If more than one power cord came with your server, use the appropriate cord for the
electrical service available at your location.
You can use the long power cord supplied with the server, or another cord, such as one
already installed in the rack.
7 If you will be using the FireWire port on the front panel of the server, connect a cable to it.
8 When all cables are in place, connect each one to its intended device.
Important When connecting peripheral devices, be sure to allow adequate space at the
front and back of the server for proper airflow and access to the rack for servicing.
42 Chapter 3
9 After all connections are complete, plug the power cord into a power source.
Warning This equipment is intended to be electrically grounded. Your server is
equipped with a three-wire grounding plug—a plug that has a third (grounding) pin.
This plug will fit only a grounded AC outlet. This is a safety feature. If you are unable
to insert the plug into the outlet because the outlet is not grounded, contact a licensed
electrician to replace the outlet with a properly grounded outlet. Do not defeat the
purpose of the grounding plug!
Because you are installing the server in a rack with other equipment, be certain that the
power outlet and any other equipment, such as a power strip, used with the rack is
designed to carry the electrical load of multiple devices. Check the documentation for
your rack for any special instructions.
With the server in the rack and the cables in place, you can prepare to set up the Mac OS X
Server software.
Preparing the Server for Software Setup
When the server is installed and secured, you are ready to set up the software.
You can configure the server locally or use the remote setup tools. If you want to configure
the server software where the server and rack are located, you can do one of the following:
m Connect a monitor, keyboard, and mouse to the server.
You can connect the monitor to the VGA port and connect the keyboard and mouse to the
USB ports on the server’s back panel. If a KVM (keyboard-video-mouse) switch is installed in
the rack, you can use it. See the documentation for the KVM switch for instructions.
m Connect a computer running Mac OS X to the server using an Ethernet connection on the
same subnet as the server.
If you want to set up the software from another location, you can work at a computer on the
server’s network, using the remote server administration software and command-line tools.
You need to install the administration software on the portable or network computer before
you can set up the software.
See Chapter 4, “Using Your Server,” on page 45 for more about software configuration.

5 Installing or Replacing Server
Components
Your server is designed so that you can install or exchange drive modules while the server is
operating. The server should be turned off before opening it to install or exchange other key
components.
When working with the server hardware, always guard against static electricity, which can
damage electronic components. Touch a metal surface before handling RAM or an expansion
card or working inside the server.
49
When installing components, it’s wise to wear a wrist grounding strap that prevents static
electricity from discharging into electronic components.
It is good practice to use
an antistatic wrist strap
when accessing the
interior of the server.
You can also arrange for an Apple-authorized service provider to install or replace
components in the server. For details about this service, see the support information that
came with your server. Additional support information is available at the Apple Support Web
site: www.apple.com/support
Installing or Replacing an Apple Drive Module
The drive modules in the server are hot-pluggable; that is, you can remove one and replace it
with another drive while the server is running. A status light on each drive indicates when it’s
safe to remove a drive without losing any information.
Follow these steps to install or replace a drive module.
1 If necessary, use the enclosure key to unlock the security lock on the server’s front panel.

Adding Memory
The server has four memory slots, at least one of which is filled at the factory. Follow these
steps to add memory to the server.
You can install additional dynamic random-access memory (DRAM) in packages called
Dual Inline Memory Modules (DIMMs) in the four DRAM DIMM slots on the server’s main
logic board. You can expand your computer’s DRAM to a maximum of 2 gigabytes (GB). To
check the amounts of DRAM installed, use the Apple System Profiler (located in the Utilities
folder, in your computer’s Applications folder).
DIMMs must fit these specifications:
m PC2100 double-data-rate (DDR) Synchronous DRAM (SDRAM); also described as DDR-266
m 2.5 volt (V)
m 64-bit wide, 184-pin module
m Maximum number of memory devices on a DIMM is 16.
m Unbuffered; do not use registered or buffered DRAM.
m Height must not exceed 1.25 inches.
Important DIMMs from older Macintosh computers are not compatible with your server.
Do not use older DIMMs even if they fit into the DIMM slots.
Note: When purchasing DRAM for use in the server, make sure that the memory conforms
to the JEDEC specification. Check with your memory vendor to ensure that the DRAM DIMM
supports the correct timing modes and that the Serial Presence Detect (SPD) feature has
been programmed properly, as described in the JEDEC specification. You can purchase
memory where you bought your server.
Follow these steps to install memory in the server.
1 Shut down the server.
Be sure to alert users of the server that it will be unavailable for a period of time.
2 Unplug the power cord from the back panel of the server. (If the cable-management arm is
not attached, you also need to disconnect cables from the back panel.)

B Safety, Maintenance, and Ergonomics
Important Safety Information
For your own safety and that of your equipment, always take the following precautions.
Important The only way to disconnect power completely is to unplug the power cord.
Make sure at least one end of the power cord is within easy reach so that you can unplug the
server when you need to.
Disconnect the power plug (by pulling the plug, not the cord) if any of the following
conditions exists:
m you want to remove any parts (leave the cord disconnected as long as the cover is off )
m the power cord or plug becomes frayed or otherwise damaged
m you spill something into the case
m your server is exposed to rain or any other excess moisture
m your server has been dropped or the case has been otherwise damaged
m you suspect that your server needs service or repair
m you want to clean the case (use only the recommended procedure described later)
Be sure that you always do the following:
m Keep your server away from sources of liquids, such as washbasins, bathtubs, shower
stalls, and so on.
m Protect your server from dampness or wet weather, such as rain, snow, and so on.
m Read all the installation instructions carefully before you plug your server into a wall
socket or power strip.
m Keep these instructions handy for reference by you and others.
m Follow all instructions and warnings dealing with your system.
Electrical equipment may be hazardous if misused. Operation of this product, or similar
products, must always be supervised by an adult. Do not allow children access to the interior
of any electrical product and do not permit them to handle any cables.
73
Handling Your Computer Equipment
Follow these guidelines for handling your computer and its components:
m When the server is removed from its rack, set it on a sturdy, flat surface.
Important Do not put a monitor or any other device on top of the server. Essential
components are installed in this low-profile server, and any weight on top of the case could
damage these components.
m When connecting or disconnecting a cable, always hold the cable by its connector (the
plug, not the cord).
m Turn off your server before connecting or disconnecting a cable for a monitor or a serial
device. Failure to do so could damage your equipment or cause an interruption in the
server’s operation.
Certain components and cables—hard disks, a VGA monitor, FireWire, Ethernet, and USB
devices—are designed to be installed or removed while the server is turned on and
operating.
m Never force a connector into a port. If the connector and port do not join with reasonable
ease, they probably don’t match. Make sure that the connector matches the port and that
you have positioned the connector correctly in relation to the port.
m Take care not to spill any food or liquid on the server or other components. If you do,
turn your server off immediately and unplug it before cleaning up the spill. Depending on
what you spilled and how much of it got into your equipment, you may have to arrange
for an Apple-authorized service provider to inspect or repair the server.
m Protect the server and its components from direct sunlight and rain or other moisture.
m Keep all ventilation openings clear and unobstructed. Without proper air circulation,
components can overheat, causing damage or unreliable operation.
74 Appendix B
Protecting Your CD Drive
To keep your CD drive working properly:
m Position your server so that when the tray opens, it doesn’t bump into anything.
m Do not leave the disc tray open. If dust gets on the lens of the CD-ROM drive, the drive
may have problems reading your discs.
m Do not put anything (for instance, a cup) on top of the tray when it is open.
m Do not force the tray open by hand. In an emergency, you can use an opened paper clip
in the tiny hole near the drive to eject a disc.
m Do not wipe the lens with a paper towel or other abrasive surface. If you need to clean
the lens, see an Apple-authorized service provider for a lens cleaner.
You may want to open the tray and take out your disc before shutting down.
Power Supply
The power supply in your computer is a high-voltage component and should not be opened
for any reason, even when the computer is off. If the power supply needs service, contact
your Apple-authorized dealer or service provider.
Cleaning Your Equipment
Follow these general rules when cleaning the outside of your server:
m Use a damp, soft, lint-free cloth to clean the computer’s exterior. Avoid getting moisture
in any openings.
m Don’t use aerosol sprays, solvents, or abrasives.
Cleaning the Server’s Case
To clean the case, do the following:
1 Turn off the computer completely and then disconnect the power plug. (Pull the plug, not
the cord.)
2 Wipe the surfaces lightly with a clean, soft cloth dampened with water.

Health-Related Information About Computer Use
In most instances, you will probably set up and administer your server from a remote
location, such as a computer on the server’s network. If you work at the server rack for
extended periods, be sure to following these guidelines for avoiding muscle soreness, eye
fatigue, or other discomforts associated with computer use.
m If feasible in the server location, use an adjustable chair that provides firm, comfortable
support. The back of the chair should support your lower back (lumbar region). Follow
the manufacturer’s instructions for adjusting the backrest to fit your body properly.
m When using a keyboard at the server location, your shoulders should be relaxed. Your
upper arm and forearm should form an approximate right angle, with your wrist and hand
in roughly a straight line. Depending on the location of the monitor and keyboard
connected to the server, you may have to adjust the height of your chair so that you can
maintain a comfortable position. Your feet should be flat on the floor or on a footrest.
