• I/O Blank Plate(s) - May be removed when installing additional I/O modules.
NOTE: Blank plate (provided) must be installed if any module slot is left
empty. Installation of the blank plate is necessary for proper
cooling inside chassis.

swappable modules each with two (2) high-pressure blowers inside, provide ample
cooling for high speed drives (79 CFM each module). Each module features blower
fault detection, total usage hours, and self-adjusting blowers for optimal cooling
performance.
Blower Module LED(s) -
Green LED - Steady glow indicates normal blower operation.
