Using Your Server

If the Server Has a Problem
If you discover a problem with the server, you can assess the situation and often solve the 
problem from a remote computer. The Mac OS X Server software documentation contains 
information about restarting the server and solving some other problems; see the Quick 
Start for Xserve 
booklet to learn which parts of the software documentation to consult.
If you have access to the server itself, you can use the buttons on the front panel to change 
the server’s status. These buttons include
Power:  Press to turn the server on. 
System identifier:  This light helps you determine which server in a multiple-server rack 
has a problem. The light turns on when the server has a problem; it can also be turned on 
manually. Pressing the button next to this light turns the light off when it’s on. (Duplicates 
of the button and light are on the back panel.)
What to Do If . . .
If you detect trouble with the server, follow the guidelines below to solve the problem.
Problem
Try this
Server doesn’t start up
Start up from the system disc that came with your server. 
1. With the power off, hold in the system identifier button while 
you press the power button.
2. Continue holding in the system identifier button until the top 
row of blue lights blinks sequentially and the rightmost light in 
the bottom row turns on.
3. Release the system identifier button.
4. Wait a few moments in case there is already a disc in the 
optical drive. (That disc will be ejected.)
5. Put the system disc in the optical drive slot.
Server doesn’t recognize a 
peripheral device
When the lock on the Xserve system’s front panel is locked, the 
software ignores storage devices, keyboard and mouse, and other 
peripherals connected to the USB and FireWire ports on the 
server. Use the enclosure key to unlock the lock.
Hard disk is erased or server 
software is damaged
Reinstall system software from the system disc. (Start up from 
the disc and use the Installer to reinstall the software.)
