1 Installing the Xserve 1 This chapter shows you how to install the Xserve in an equipment rack. The information in this chapter will help you gather the tools you’ll need, choose a suitable location for the Xserve, and install it in a rack. When you’ve finished installing the Xserve, you’ll be referred to the Xserve User’s Guide for information about starting up the Xserve for the first time.
Tools and Parts You’ll Need  A medium-size (#1) Phillips screwdriver  The slide rails, rail extensions, and alignment tool that come with the Xserve Rails for use with racks of all depths (2) Short extensions for racks 24 to 29 inches deep (2) Long extensions for racks 29 to 36 inches deep (2) Alignment guide Enclosure key 8 Chapter 1 Installing the Xserve
Choosing a Suitable Location The Xserve is designed for rack mounting. Review the following paragraphs to be sure the location you choose satisfies the Xserve space, electrical, and environmental requirements. Rack Compatibility You can install the Xserve in any open or closed (cabinet-style) 19-inch-wide four-post rack from 24 to 36 inches deep using the rails included with the Xserve. The Xserve occupies 1.75 inches (1U) of vertical rack space.
Do not block the air flowing through the Xserve. Electrical Power Requirements Be sure that the available circuitry and power connections are adequate for the combined power needs of the Xserve and all other equipment in the rack. See Appendix A for information about the electrical power requirements of the Xserve. Make sure that the power connections for the Xserve and all other equipment are grounded according to local and national standards.
Installing the Xserve Follow these instructions to install the Xserve in an equipment rack. Installation Summary 1 Remove the shipping material. 2 Assemble a pair of slide rails that are the right length for your rack. 3 Install the rails loosely in the rack. 4 Align and secure the rails. 5 Slide the Xserve into the rack. Installing Optional Components Before You Begin To work inside the Xserve, you need to remove it from the rack.
Step 1: Remove the Protective Shipping Materials 1 Remove the Xserve from its box and place it on a flat surface. 2 Remove the protective faceplate by unscrewing the thumbscrews on each side of the faceplate and lifting it off. Protective faceplate 3 Remove any plastic film covering the front or top of the Xserve. Note: Do not remove the small plastic protector in the optical drive slot. Leave this protector in place until the Xserve is secured in the rack.
Step 2: Assemble the Mounting Rails The Xserve comes with both short and long extensions that you combine with standard front rails to create a pair of rails that are the right depth for your rack. Short extension These pegs engage the slots in the extension. Rail Long extension 1 Slide a matching rear extension onto each of the two front rails. Engage the pegs in both slots. The extension goes on the outside of the rail. This end is up. This notch should be on the bottom.
Step 3: Mount Rails Loosely in the Rack 1 Place an assembled rail in the rack (it will support itself temporarily while you gather the fasteners). The way you fit the rail depends on the rack. Â If you have a square-hole rack, start with the rail flanges inside the posts and expand the rail between the front and rear posts until the small round guide on each flange extends through the rail. 14 Expand the rails so they fit inside the rack posts.
 If you have a threaded-hole rack, start with the rail flanges outside the rack posts and compress the rail into position. Position the spacer over the threaded guide on the rail assembly. Compress the rails so that they fit on the outside of the rack posts. This end is up. Use either eight 10-32 or eight M5 screws (supplied), depending on which type your rack requires. 2 Slide a spacer, arrow up, over the small round guide at the ends of each rail and install the mounting screws finger tight.
Step 4: Align and Secure the Rails To make sure the Xserve slides easily in and out of the rack, use the alignment guide to position the rails in the rack before tightening the mounting screws. 1 Insert the alignment guide in the front of the rails. Insert the alignment guide into the rails and tighten all the screws.
Step 5: Slide the Xserve into the Rails 1 Guide the slides on the Xserve into the channels on the rails. Important: Make sure both the left and right slides on the Xserve go inside the rail channels. If you have difficulty, set aside the Xserve and use the alignment guide to check the spacing between the rails. Optical drive protector Thumbscrews 2 Slide the Xserve into the rack until it stops. 3 Tighten the thumbscrews at each end of the front panel to secure the Xserve in the rack.
Step 6: Connect the Cables 1 Connect a power cord to the power supply and secure it with the wire clip. Note: The fan in the power supply and some system status lights come on when you connect the power cord, before you turn on the Xserve. 2 Connect the network cables. Note: If you’re using only one Ethernet cable, connect it to port 1.
Step 7: Connect a Keyboard, Display, and Mouse (Optional) You can connect a display, keyboard, and mouse directly to the Xserve. You can also manage the Xserve without connecting a display or keyboard by using tools such as Server Admin, Server Monitor, Apple Remote Desktop, and the command line. Display port USB 2.0 ports (2) VGA adapter 1 Connect the keyboard to one of the USB ports on the back panel. 2 Connect the mouse to the second USB port or to the keyboard. 3 Connect the video cable.

Power supply bays You can install one or two power supplies in the Xserve. When two supplies are installed, they share the load. If one supply fails, the other takes over the full load. For information, see “Removing or Installing a Power Supply” on page 28. Battery The battery on the main logic board powers the system clock and preserves basic system settings (in NVRAM) when power supplies are disconnected. For information, see “Replacing the Battery” on page 44.
Installing or Replacing an Apple Drive Module The drive modules in the Xserve are hot-pluggable, so you can add, remove, or replace them while the Xserve is operating. A status light on the drive handle indicates when it’s safe to remove a drive without risk to the information stored on it. About Drive Modules for the Xserve The Xserve accepts both SAS (Serial Attached SCSI) and SATA (Serial ATA) drive modules.
2 Remove the blank drive module or the drive module that’s currently installed. If there is a blank drive module in the bay, press the handle on the front to pop it out. Then pull the module out and put it in a safe place. Press the blank drive module to pop out the handle. Important: Save the blank drive module. Always keep a blank drive module in any unused drive bay to maintain proper airflow through the Xserve.
Remove the blank drive module from the bay. If there is a drive module already in the bay: a Make sure the drive currently in the bay is not being used by any application or being shared by the Xserve. (See the Mac OS X Server documentation for information about shared volumes.) b Unmount all volumes hosted by the drive using the Mac OS X Server command-line tools or by dragging the volume icons to the Trash. c Press the handle on the drive module so the handle pops out.
3 Pick up the drive module you are installing, press and release its handle to open it, and slide the module into the bay until it is firmly seated. 4 Press the handle in flush with the front panel. The disk status light turns green to indicate normal operation.
Removing or Installing a Power Supply You can replace or install a power supply from the back panel without removing the Xserve from the rack. If the Xserve has two power supplies, they are hot-swappable; the Xserve continues to operate using only one supply while the second is removed. To remove a power supply: 1 Unplug the power cord from the power supply you are removing. 2 Pull the handle to release the power supply and slide it out of the bay.
To install a power supply: 3 Pull to open the handle on the new power supply, slide it all the way into the bay, and then press the handle to seat the power supply and lock it in place. Slide the power supply in and press the handle to seat it. 4 Connect the power cord to the power supply. If the Xserve is already running on a second power supply, the status light on the new supply turns green to indicate normal operation as it starts sharing the load.
Opening and Closing the Xserve Before you can install or replace memory, PCI cards, or the system battery, you need to shut down the Xserve, remove it from the rack, and open it.

Safety and Maintenance B Appendix B 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 Xserve when you need to.
Be sure that you always do the following: Â Keep the Xserve away from sources of liquid, such as washbasins, bathtubs, shower stalls, and so on. Â Protect the Xserve from dampness or wet weather, such as rain and snow. Â Read all the installation instructions carefully before you plug the Xserve into a wall socket or power strip. Â Keep these instructions handy for reference by you and others. Â Follow all instructions and warnings dealing with the Xserve. Electrical equipment may be hazardous if misused.
 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.  Take care not to spill any food or liquid on the Xserve or other components. If you do, turn off the Xserve immediately and unplug it before cleaning up the spill. Arrange for an Apple-authorized service provider to inspect or repair the Xserve.
Cleaning the Xserve Follow these general rules when cleaning the outside of the Xserve: Â Use a damp, soft, lint-free cloth to clean the exterior. Avoid getting moisture in any openings. Â Don’t use aerosol sprays, solvents, or abrasives. Cleaning the Xserve 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.
 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.  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 roughly in a straight line.
