Blower Module
•OK—Left LED; Green. When on, this LED indicates that the blower module is operating normally. This LED should come on as soon as the blower module is installed and receives power from the backplane connector.
•FAIL—Right LED; Red. The red LED should remain off during normal operation. If the red LED is on, the system has detected a fan failure or other fault in the blower module. Replace the existing blower module with a spare.
