4U steel chassis with six 5.25" and one 3.5"
open drive bays, and one hidden 3.5" drive bay. It will accommodate most 14-slot backplanes.
The front door is lockable and provides access to the drive bays.
The status indicators and dust filters are also located behind the front door.
This particular chassis model provides a Fault Detection Module (FDM) to monitor internal temperature, CPU fans and system fans. The FDM provides fault status indication at the front panel and an audible alarm when a fault is detected.
NOTE: At this time, the FDM is ONLY monitoring internal temperature and system fans. It is not monitoring the CPU fans or the DOM power supply fans.
