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.
