B 23 4 4 Troubleshooting The following sections describe common problems with possible solutions which can occur with your 4 4 1 Storage Scaler 6000 system Thermal Control The Storage Scaler 6000 Enclosure uses extensive thermal monitoring and takes a number of actions to ensure component temperatures are kept low and also to minimize acoustic noise Air flow is from the front over the drive section through the midplane through the I O modules to rear of the enclosure If the ambient air is cool below 25 C and the fans are observed to increase in speed then some restriction on airflow may be causing additional internal temperature rise Note 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 PCMs fitted 1 Check the installation for any airflow restrictions at either the front or rear of the enclosure A minimum gap of 25mm at the front and 50mm at the rear is recommended 2 Check for restrictions due to dust build up clean as appropriate 3 Check for excessive re circulation of heated air from rear to the front Use in a fully enclosed rack installation is not recommended 4 Check that all Blank modules ar
