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 dierence between the Xserve (Late 2006) model and the Xserve
(Early 2008) model is the port next to the system identier 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 at-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 Identier Light/Button
The identier 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 identier button.) This indicator will help you locate which Xserve in a rack needs servicing.

In addition, you can use the identier 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 identier 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 dierent 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.
