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 finish 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 threaded-hole or square-hole rails, depending on which came with the Xserve. The Xserve occupies 1.75 inches (1U) of vertical rack space.
Space Requirements Air to cool the Xserve flows from front to back. Make sure nothing blocks any of the openings in the front and back panels and case of the Xserve. When installed, the Xserve slides in and out of the rack from the front. Make sure you have at least 36 inches clear in front of the Xserve so you can remove it. Do not block the air flowing through the Xserve.
Operating Environment Make sure that the ambient temperature in the rack is within the limits established for the Xserve and all other equipment. See Appendix A for the Xserve operating temperature requirements. Make sure that both the rack itself and the room where the rack is located are sufficiently ventilated to maintain the necessary temperature range. Installing the Xserve Follow these instructions to install the Xserve in an equipment rack. Installation Summary 1 Remove the shipping material.
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 threaded-hole rack, start with the rail flanges outside the rack posts and compress the rail into position. 14 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.
 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. Expand the rails so they fit inside the rack posts. Position the spacer on the outside of the post, and over the threaded guide on the rail. Position the spacer so the small block on the back engages the square hole in the rack support.
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 If you’re not using an Xserve RAID card, the drive modules in the Xserve are hotpluggable, 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. If you are using an Xserve RAID card, you can add, remove, or replace failed hard drives while the Xserve is operating.
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. WARNING: Install power supplies with a rating of at least 750 Watts. The power supplies that come with previous Xserves are rated at less than 750 Watts.
To install a power supply: 1 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.
