You can check the status of the Xserve whether you’re
nearby or in a remote location.
This chapter shows how to check whether the Xserve is operating normally, how to
get details if the Xserve detects a problem, how to interpret the hardware status lights,
and how to monitor conditions such as the various internal temperatures and power
supply voltages.
Checking the Status of Mac OS X Server Services
This chapter is about monitoring Xserve hardware status. For information about
software status and how you can use the Server Admin application to check the state
of individual services hosted by Mac OS X Server on an Xserve, see the Mac OS X
Server documentation suite at www.apple.com/server/resources.
Checking the Status of the RAID Card Battery
If you have an Xserve RAID Card, you can use RAID Utility to check the status of
the write cache backup battery. If the battery isn’t fully charged, it is probably
undergoing normal charging or conditioning. For information about the battery,
see the RAID Utility User Guide (at www.apple.com/xserve/resources.html) or the
RAID Utility onscreen help.
Local and Remote Monitoring
If you’re near the Xserve, you can glance at the status light on the front panel and
know immediately if the Xserve has detected a problem. See “Interpreting the Xserve
Status Lights” on page 19.
If you connect a display and keyboard, you can open the Server Monitor application to
view detailed status information for critical components. See “Using Server Monitor” on
page 23.
