Problems and Solutions
If the Xserve doesn’t start up
Try starting up from the Mac OS X Server Install DVD that comes with the Xserve.
For information about startup alternatives, see Chapter 2, “Starting Up the Xserve,”
on page 12.
If the Xserve doesn’t start up automatically after a power failure
Choose a startup disk from the Startup Disk pane of System Preferences. Even when
you enable “Restart automatically after a power failure,” the Xserve might not restart
when the enclosure is locked unless you have explicitly chosen a startup disk.
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 the Xserve or a remote administrator computer.
