volume of the Xserve installation drive (that is, the volume on the Xserve that will be
the system’s startup disk).
Note: You can use either Server Assistant or the Terminal application and commandline tools to control the installation.
See Mac OS X Server Command-Line Administration, available at www.apple.com/server/
documentation, for information about using command-line tools with the Terminal
application.
24 Chapter 4 Updating or Installing Software on the Xserve
Using Commands over the Serial Port to Install from the Optical Drive
Another way to install Mac OS X Server on the Xserve without a keyboard or display is
to use the Xserve serial port and optical drive.
To use the serial port and command line to install:
1 Connect a terminal or a computer running terminal emulation software to the serial
port on the back of the Xserve.
2 Insert the Mac OS X Server installation disc in the Xserve optical drive.
3 Use the front panel controls to start up the Xserve from the optical drive. For
information, see “Choosing a Startup Method from the Front Panel” on page 12.
The Xserve starts up from the disc in the optical drive and a login prompt appears in
the terminal window.
4 Log in as the user “root” with the password consisting of the first 8 characters of the
Xserve serial number.
5 If necessary, use the diskutil tool to erase, format, or partition the drive you plan to
install Mac OS X Server on. For help, type the command without any parameters:
$ diskutil
6 Switch to the directory on the installation disc that contains the install packages.
$ cd /System/Installation/Packages
7 Run the installer tool, specifying the Mac OS X Server metapackage:
$ installer -pkg ./OSInstall.mpkg -target /Volumes/
where
volume
is the name of the volume where you want to install the software.
volume
-verboseR
When the installation finishes, you can use an administrator computer to run Server
Assistant and configure the Xserve, or take advantage of the autosetup features of
Mac OS X Server. For information, see Mac OS X Server Getting Started on the Admin
Tools disc that comes with the Xserve.

Problems and Solutions
If the Xserve doesn’t start up
Try starting up from the Mac OS X Server disc that comes with the Xserve. For
information about startup alternatives, see Chapter 2.
If the Xserve doesn’t start up and all 16 system activity lights flash continuously
A memory DIMM is bad.
If the system identifier light is flashing
The Xserve has detected a problem. To find out what’s wrong, open the Server Monitor
application on either the Xserve or a remote administrator computer.
If there is no image on the connected display or the display appears frozen
Make sure the enclosure is not locked. If you connect a display to a running Xserve, the
image on the display may be garbled or missing. If this occurs, restart the Xserve.
Alternatively, you may be able to adjust the display image using a remote computer.
Open System Preferences for the Xserve, open the Displays pane, and click
Detect Displays.
If you have difficulty removing the cover
Use the enclosure key to make sure the enclosure lock on the front panel is unlocked.
If the Xserve doesn’t recognize a peripheral device
When the enclosure lock on the Xserve front panel is locked and the enclosure lock
preference in the Security pane of System Preferences is on, the Xserve ignores storage
devices, keyboard and mouse, and other peripherals connected to the USB and
FireWire ports. The light next to the enclosure lock is on when the lock is engaged.
If you have difficulty removing a drive module
Use the enclosure key to make sure the enclosure lock on the front panel is unlocked.
If the Xserve doesn’t recognize a drive module when the Xserve is locked
Occasionally a drive module won’t be recognized if the Xserve is locked and the drive
module’s handle has been opened before the system powered up. If this occurs, unlock
the enclosure lock, remove the drive module and replace it, and then close the drive
module’s handle. If the drive module still isn’t recognized, restart the Xserve.
If a drive module light is yellow or red
If the upper LED for a drive module is yellow or red, there is a problem with the drive. If
possible, replace the drive. Check the Server Monitor application for information about
the drive’s status.
If you can see the Xserve on the network but can’t access it
If the Xserve is on a closed network and your administrator computer is on both the
closed network and another network, your administrator computer defaults to the
other network when you try to connect to 169.254.x.x addresses. To correct this, set up
a 169.254.x.x address on your administrator computer so it will have a route to the
169.254 (closed) network.
If the hard disk is erased or Xserve software is damaged
Reinstall the Mac OS X Server software. For information about installation methods, see
Chapter 4.
Using Apple Xserve Diagnostics Software
The Xserve comes with Apple Xserve Diagnostics software that you can use to test the
Xserve hardware. To learn about Apple Xserve Diagnostics, see the user’s guide in the
Documentation folder on the Admin Tools disc that comes with the Xserve.
