You can also connect a management console to the Xserve serial port and manage the
Xserve using command-line tools. See “Using the Serial Port” on page 22.
If you’re away from the server rack, you can use the Admin Tools disc to install server
administration tools on a Mac OS X computer, turning it into an administrator
computer. You can then use Server Monitor on the administrator computer to check
the Xserve status, or have an email alert sent to interested individuals if the Xserve
detects any of a variety of conditions. See “Using Server Monitor” on page 23.
Identifying the Xserve in a Rack
If you have several Xserve systems in a rack, you can use the system identifier lights
to flag and identify a particular Xserve. The light can help you return to the right server
when you walk around to the other side of the rack. You can also turn on the system
identifier light from the Server Monitor application so you can find the Xserve in
the rack.
