Diagnostic Tools
Diagnostic Tools
Xserve RAID includes built-in sensors that detect and report on hard drives, internal
temperature, cooling module status or failure, and power status or failure. You can monitor
the system’s operation via these sensors and two diagnostic tools: indicator lights on the
front and back of the system and remote monitoring software.
Status Lights
Status lights are located on the front and back panels of Xserve RAID. In addition, there
are status lights on the host adapter card.
