Xserve Overview

CHAPTER

Preparing to Install Your Server

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.

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.

Remove the clear plastic film that

Do not block the air flowing through the server.

covers the front so that

airflow is not

restricted.

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.

To provide access to the server’s back panel and cables, leave at least 24 inches clear behind the server.

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.

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

Storage

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:

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.

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.

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.

See Appendix A, “Speciﬁcations,” for more information about electrical power requirements for the server.

Chapter 2

This model is certiﬁed only as a component for use with other equipment, where the suitability of the combination has been determined by a Nationally Recognized Testing Laboratory.

Operating Environment

The operating environment for the server’s rack must meet certain requirements:

Verify that the temperature range of the rack’s location is within the limits established for the server and all other components.

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 ensure

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 slide out more than one unit 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 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

Security

Whatever the location of the server and rack, it should be secure. m Make sure that only authorized staff members or technicians can gain access to the rack’s

location.

m If using a server cabinet that is not in a secure room, be sure that the cabinet is adequately

locked 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 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.

CHAPTER

3 Installing Your Server in a Rack

Xserve is speciﬁcally designed for rack mounting. It is not designed for use as a desktop system.

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 24 or 26 inches deep or 29–36 inches deep m cabinet with four-post rack inside, 19 inches wide and 29–36 inches deep m two-post (also called “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, along with some extra screws of each type. You need to supply mediumsized and very small Phillips screwdrivers for the installation.

Getting Ready to Install

As noted previously, you can install the server in a four-post rack of varying depth or a twopost rack. Instructions for these procedures are given below. Preparations for installing are the same regardless of the type of rack you use.

Important Check the documentation for your rack for any special requirements.

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. (Everything

except the screwdrivers is 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 that is between 29 and 36 inches deep, you’ll use two small

brackets (each has two rivets), two long U-shaped braces, and eight attachment screws. Also get the cable-management arm and the two screws to attach it to the server.

m For a four-post rack that is 24 or 26 inches deep, you’ll use two small brackets (each

with one post), four attachment screws, and two short screws.

m For a two-post rack, you’ll use two L-shaped brackets, four attachment screws, and four

short 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 ﬁts 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 (see “Guidelines for Server Installation” on page 19). 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 positioning 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 the mounting template or 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.

Preparing 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.

There is one screw on either side of the server.

Remove the four thumbscrews that hold the protective faceplate in place, and remove the faceplate by lifting it straight up.

Protective faceplateRemove the two shipping screws.

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 57.

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 59.

Drive module bay 1 Drive module bay 2 Drive module bay 3 Drive module bay 4

Important When installing a drive module for the ﬁrst time, remove the blank drive

module and save it for possible future use. A blank module should always be placed in an empty drive bay to maintain proper airﬂow through the server.

28 Chapter 3

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 that is 29–36 inches deep, proceed to “Installing the Server in a Four-Post Rack or Cabinet” on page 29. If you have a short rack that is 24 or 26 inches deep, go to “Installing the Server in a Short Four-Post Rack” on page 42. If you have a twopost rack, go to “Installing the Server in a Two-Post (Telco) Rack” on page 47.

Installing 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 Slide the server into the cover and secure it. m Install the cable-management arm.

Note: You cannot use the cable-management arm in a short rack, 24 or 26 inches deep. For details on installing the server in a short rack, see “Installing the Server in a Short Four-Post Rack” on page 42.

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 center of the cover while you attach it to the rack.

30 Chapter 3

2 Screw the ﬂanges at the front of the cover to the front posts of the rack.

Important Make sure that the cover of the system is at right angles to both posts. Use the

mounting template provided with the system or a right-angle measuring device to determine that the cover is square to the posts on both sides. If the cover is not installed squarely, its shape may change slightly and the cover may not hold the server in the correct position.

Be careful not to overtighten the ﬂange screws. Doing so could change the shape of the cover.

Temporarily place the mounting template over the two posts on the cover.

Attach the cover to the two front rack 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 (some are provided with the server) into the appropriate hole before attaching the screw. Several of these clips, also called “cage nuts,” are included with the mounting hardware.

Some racks have prethreaded holes.

Installing Your Server in a Rack 31

Other racks use various types of nuts to secure equipment.

3 At the back of the server, position the small bracket inside the server’s cover so that the head

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 high 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

post of the rack, and screw the brace’s ﬂange to the post.

Attach the cover to the two rear rack 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 posts.

Installing Your Server in a Rack 33

Place the Server in the Rack

Once you’ve attached the cover, you can put the server into the rack.

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.)

34 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 the cable-management arm and cables for the server’s connections.

Install the Cable-Management Arm and Cables

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.

If you are not installing the cable-management arm, see “Connect Cables Directly to the Server” on page 50 for details on connecting cables.

Important To open the server with the cables attached, you must install and use the cable-

management arm. You can use the cable-management arm only with a four-post rack.

If your rack is the same depth as the server (or an inch or so deeper), you attach the cablemanagement arm to the left rear post of the rack. If your rack is several inches deeper than the server, you attach the cable-management arm to the left brace that supports the back of the server.

The steps that follow explain how to connect cables to the cable-management arm and attach the arm either to the left rear post or to the left brace at the back of the server.

Connect Cables to the Cable-Management Arm

Before you attach the cable-management arm to the rack or support brace, you need to connect the cables to the arm.

Important To 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 the cables to the cable-management arm.

1 Gather the cables you will connect to the server’s back panel, along with the power cord.

(Use the cord supplied with the server.)

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.

Installing Your Server in a Rack 35

3 Hold the cable-management arm in the orientation you will use to attach it to the rack or

support brace.

The short part of the arm should be closer to the server’s back panel and the elongated holes on the long part of the arm should face the left back post of the rack (as you face the back of the server).

Cable-management arm

4 Bunch together the cables and power cord and lay them along the cable-management arm,

starting at the server side of the short part of the arm and moving to the side closer to you on the long side of the arm.

The connectors for the server should be between the short part of the arm and the back panel, with enough free cable to reach the connectors on the back of the server.

Gather all the cables you will be connecting to the server, 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 ensure unobstructed extension.

5 Use the hook-and-loop straps provided to secure the cables to both parts of the arm at

several points.

Attach the Cable-Management Arm to the Rack

If the rear posts of your rack are ﬂush with the server’s back panel or within an inch of it, you attach the cable-management arm to the left rear post of the rack.

If your rack is more than an inch deeper than the server, see “Attach the Cable-Management Arm to the Support Brace” on page 39 for mounting instructions.

36 Chapter 3

Follow these steps to attach the cable-management arm to the rack.

1 At the front of the server, loosen the thumbscrews securing it to the rack and slide the server

a few inches forward.

Moving the server forward allows you to check the position of the cable-management arm after you mount it.

2 Position the cable-management arm so that the short part is closer to the server’s back panel

and the elongated holes on the long part align with the holes on the brace attached to the left post.

3 While holding the arm in the correct position, disconnect the upper mounting screw that

holds the left brace to the left post, place the corresponding hole of the cable-management arm’s long side over that opening, and reconnect the mounting screw.

Important Be sure to support the server from below as you remove and replace the

mounting screws one at a time.

Place the cable-management arm over the U-shaped brace, and secure it to the rack. It is important that you remove and then reinstall one screw at a time so that the server is supported at all times.

Support the server from below while attaching the cable-management arm.

Remove and then reinstall the mounting screws one at a time.

4 Disconnect the lower mounting screw, line up the corresponding part of the arm, and

reconnect the mounting screw.

Support the server from below while doing this step.

5 Verify that the arm’s position is correct by moving the arm inward so that it swings under the

cover of the server.

If the arm hits the cover or is not level as you move it, you need to adjust its position by unscrewing one or both mounting screws and moving the arm up or down slightly until it is level and moves smoothly under the server’s cover.

7 Connect the power cord and its retaining clip to the back of the server.

If more than one power cord came with your server, use the appropriate cord for the electrical service available at your location.

Note: You may need to bend the cord near its plug to ﬁt it into the server. Bending the cord will not affect its operation.

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.

8 Connect the other end of the cables to the appropriate devices.

9 Close the server and tighten the thumbscrews to secure it in the rack.

38 Chapter 3

10 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 ﬁts 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.

For details on disconnecting cables from the server’s back panel, see “Disconnecting Cables From the Server’s Back Panel” on page 51.

With the server in the rack and the cables in place, you can prepare to set up the Mac OS X Server software.

Attach the Cable-Management Arm to the Support Brace

If the rear posts 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 left side of the server (not to the rear post). Otherwise the arm will not extend properly when you open the server in the rack.

If the rear posts of your rack are ﬂush with the server’s back panel or within an inch of it, see “Attach the Cable-Management Arm to the Rack” on page 36 for mounting instructions.

Follow these steps to attach the arm to the left support brace.

1 At the front of the server, loosen the thumbscrews securing it to the rack and slide the server

a few inches forward.

Moving the server forward allows you to check the position of the cable-management arm after you mount it.

2 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.

3 Hold the cable-management arm with the long part closer to you and fold the hinged section

of the long part 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 farthest from you.

Installing Your Server in a Rack 39

4 Position the cable-management arm so that the hinged section is on the inside of the left

brace, about 2 inches behind the server’s back panel.

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.

Clamp Screw Cable-management armU-shaped bracket

5 Hold the arm in place and put the clamp you detached on the opposite side of the arm, so

that the screw hole in the center shows through the open part of the brace.

6 Insert the screw into its hole and tighten it so that the arm is fastened to the brace.

7 Verify that the arm’s position is correct by moving the arm inward so that it swings under the

cover of the server.

With the server in the rack and the cables in place, you can prepare to set up the Mac OS X Server software.

Installing Your Server in a Rack 41

Installing the Server in a Short Four-Post Rack

Some four-post racks are shorter than the Xserve system. You can install the server in a short rack that is 24 or 26 inches deep using special brackets provided for this purpose. You cannot use the cable-management arm with a short rack.

When you install the Xserve system in a short four-post rack, the back of the server extends beyond the rack’s rear posts. Therefore, you cannot install the system in a short enclosed cabinet.

Important Be sure to check the documentation for your rack for any speciﬁc mounting

instructions.

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 Connect the rear mounting hardware to the server’s cover. m Attach the short-rack mounting brackets to the rear posts of the rack. 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 center of the cover while you attach it to the rack.

42 Chapter 3

2 Screw the ﬂanges at the front of the cover to the front posts of the rack.

Important Make sure that the cover of the system is at right angles to both posts. Use a

right-angle measuring device or object to determine that the cover is square to the posts on both sides. If the cover is not installed squarely, its shape may change slightly and the cover may not hold the server in the correct position.

Be careful not to overtighten the ﬂange screws. Doing so could change the shape of the cover.

Temporarily place the mounting template over the two posts on the cover.

Attach the cover to the two front rack 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 prethreaded holes.

Installing Your Server in a Rack 43

Other racks use various types of nuts to secure equipment.

3 Just beyond the rear post of the rack, position the short-rack bracket beside the cover so that

the small pin on the bracket ﬁts into the oblong hole closest to the post.

The small pin on the bracket faces inward, toward the cover, and it is near the top of the bracket. The L-shaped ﬂange at one end of the bracket faces away from the cover and is close to the rack’s rear post.

Note: One of the short-rack brackets is designed for the left side of the cover and the other ﬁts the right side. Be sure to use the correct bracket on each side.

Insert the pin on the short-rack bracket into one of the oblong holes in the cover. There are two places to attach the short-rac bracket; use the one that best fits your rack.

Each short-rack bracket is designed to be used on only one side of the cover. Orient the right short-rack bracket (as viewed from the front of the system) as shown. The left short-rack bracket is inserted on the other side of the cover.

4 Insert one short screw through the top hole in the bracket and use it to fasten the bracket to

the cover. Do not tighten the screw all the way.

Be sure that you can still move the bracket back and forth.

Insert one short screw through the top hole in each short-rack bracket and tighten the bracket snugly against the top cover. Do not tighten the screws completely—leave them loose enough so that you can adjust the short-rack bracket slightly if you need to. You’ll tighten these screws completely later.

44 Chapter 3

5 Slide the bracket toward the rear post until the bracket’s ﬂange aligns with the post, and use

two attachment screws to secure the bracket to the post.

Secure the bracket to the rear rack post using two of the attachment screws provided.

After the cover has been firmly attached to the rack, tighten the two short screws completely.

6 Tighten the screw that secures the short-rack bracket to the cover.

7 Attach the second short-rack bracket to server’s cover and the rear post, as described in steps

3 through 6.

Place the Server in the Rack

Once you’ve attached the cover, you can put the server into the rack.

1 At the front of the rack, lift the server to the level of the enclosure’s cover and slide the

server into the cover.

Insert the server into the cover and slide it all the way back.

Installing Your Server in a Rack 45

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.)

Once you’ve placed the server in the rack, you can connect the power cord and cables directly to the back panel. See “Connect Cables Directly to the Server” on page 50 for details. You cannot use the cable-management arm on an Xserve system that is installed in a short rack.

46 Chapter 3

Installing 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 “Preparing the Server for Installation” on page 25 for details.)

1 Attach the small L-shaped brackets to the sides of the server enclosure’s cover with four of

the short screws provided.

Attach the two telco mounting brackets to the server’s cover using four of the short screws provided.

Installing Your Server in a Rack 47

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.

Installing Your Server in a Rack 49

Connect Cables Directly to the Server

Once the server is secured in the rack, you can connect the cables and power cord directly to its back and front panels. You must connect the cables and power cord directly if you mount the server in a two-post rack.

Follow these steps to connect cables for network connections and peripheral devices directly to the server (without mounting the cable-management arm).

1 Gather 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 Label each cable so that you can 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 the appropriate port.

See “Your Server at a Glance—Back Panel” on page 12 for details on ports.

4 Connect the power cord and its retaining clip to the back panel.

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.

If more than one power cord came with your server, use the cord appropriate 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.

5 If you will be using the FireWire port on the front panel of the server, connect a cable to it.

6 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.

50 Chapter 3

7 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

With the server in the rack and the cables in place, you can prepare to set up the Mac OS X Server software.

Disconnecting Cables From the Server’s Back Panel

The compact size of the Xserve system may make it difﬁcult to disconnect a cable, such as an Ethernet network connection or a ﬁbre channel cable, from the back panel. If you have difﬁculty compressing the plastic tab on the cable’s connector, use a small tool such as a tiny ﬂat screwdriver to compress the tab as you pull the connector from its socket.

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 KVM switch documentation 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 remote computer before you can set up the software.

See Chapter 4, “Using Your Server,” on page 53 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.

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 website: www.apple.com/support.

58 Chapter 5

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 shut off 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.

The above model is certiﬁed only as a component for use with other equipment, where the suitability of the combination has been determined by a Nationally Recognized Testing Laboratory.

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 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.

84 Appendix B

Protecting Your Optical Drive

To keep your optical drive working properly: m In an emergency, you can eject a disc by holding in the power button as the system

starts up.

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 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.
