Xserve (Late 2006) Take Apart — General Information 8 General Information Overview The Xserve (Late 2006) and Xserve (Early 2008) models are server computers designed to mount into a rack; Apple recommends that you remove the server from the rack before replacing or installing all parts except hard drives. You can replace hard drives while the Xserve is operating and still in the rack. The only noticeable external difference between the Xserve (Late 2006) model and the Xserve (Early 2008) model is the port next to the system identifier button on the front bezel. On the Xserve (Late 2006) model, it is a FireWire 400 port; whereas on the Xserve (Early 2008) model, it is a USB port, as shown below.
Xserve (Late 2006) Take Apart — General Information 9 To distinguish the Xserve (Late 2006 or Early 2008) models from the previous Xserve G5 model, check the rear panel. Xserve (Late 2006) and Xserve (Early 2008) have two power supply bays on the right side of the rear panel. Previous Xserve G5 models have a single, built-in power supply. What’s New See “General Information” in the Troubleshooting chapter for an overview of new features in the Xserve models. Front and Rear Panel Ports and Indicators See “External Views” in the Views chapter for descriptions of all front and rear panel ports, switches, buttons, and LED indicator lights. Mounting in a Rack For information on mounting Xserve (Late 2006) in a rack, see the Xserve (Late 2006) Setup Guide. Tools You will need the following tools: Phillips #2 scewdriver • Phillips #1 screwdriver • Small flat-blade screwdriver • Nylon probe tool or similar plastic pry tool • Needlenose pliers • If the Xserve is locked, you will also need the Xserve’s Allen wrench key. Note: Many take-apart procedures do not require tools because several internal components are fastened with thumbscrews for easy removal and replacement. Server Identifier Light/Button The identifier light on the Xserve’s front panel turns on when internal sensors or a systems administrator detects a problem with the Xserve. ( The light can also be turned on by pressing the identifier button.) This indicator will help you locate which Xserve in a rack needs servicing.
Xserve (Late 2006) Take Apart — General Information 10 In addition, you can use the identifier button to select several alternative startup methods from the front panel. See “Selecting an Alternative Startup Method from the Front Panel” in the Troubleshooting chapter. Note: A duplicate identifier light/button is on the Xserve’s back panel. A Note on the Images The photos and drawings in this manual were based on a pre-production unit. Your Xserve may look slightly different from the one shown in the images. Likewise, the instructions apply to more than one Xserve model. Unless exceptions are noted, the steps and sequence are the same for each model.
