1. If the ambient air is cool below 25 C 77 F and the fans increase in speed a restriction on airflow may be causing additional internal temperature rise This is not a fault condition The first stage in the thermal control process is for the fans to automatically increase in speed when a thermal threshold is reached This may be caused by higher ambient temperatures in the local environment and may be perfectly normal Note This threshold changes according to the number of drives and power supplies fitted Check the installation for any airflow restrictions at the front or rear of the enclosure A minimum gap of 25 mm 1 inch at the front and 50 mm 2 inches at the rear is recommended If this occurs take the following actions Check for restrictions due to dust buildup and clean as appropriate Check for excessive recirculation of heated air from rear to the front Use in a fully enclosed rack installation is not recommended Verify that all blank modules are in place Reduce the ambient temperature Thermal alarm issues If the OPS panel System Fault LED is ON a Fault LED is lit on one or more power supply modules an audible alarm is sounding or the air temperature exiting power supply is above 55 C 1319F this signals a thermal alarm issue When the internal temperature measured in the airflow through the enclosure exceeds a preset threshold a thermal alarm will sound This can also occur when a cooling2.
