- 2 Check for other AMBER LED indications on the drive carriers. If none are evident then there may either be an ESI processor problem or a Backplane problem.
- 3 Ops Panel module faulty. Please contact your supplier.
- 4.5.2 Power Supply/Cooling Faults
- 1 Ops Panel FAULT LED AMBER
- 2 An AMBER LED on one or more Power Supply/Cooling Modules.
- 3 Audible Alarm Sounding.
- 1 Any power fault.
- 2 A fan failure.
- 3 A thermal condition which could cause PSU overheating.
- 1 Check Power On/Off Switch on rear of Power Supply/Cooling module is switched ON.(not accessible on later models)
- 2 Check AC Mains Connections to Power Supply/ Cooling module is live.
- 3 Disconnect the Power Supply/Cooling module from mains power and remove the module from the system. Re-install: if problem persists, replace Power Supply/Cooling Module.
- 4 Reduce the ambient temperature.
- 4.5.3 Thermal Control
- 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 are in place.
- 5 Reduce the ambient temperature.
- 4.5.4 Thermal Alarm
- 1 Ops Panel FAULT LED AMBER.
- 2 An AMBER LED on one or more Power Supply/Cooling Modules.
- 3 Audible Alarm Sounding.
- 4 Air temperature exiting PSU above 55˚C.
- 1 Check local ambient environment temperature is below the upper 40˚C specification.
- 2 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.
- 3 Check for restrictions due to dust build-up, clean as appropriate.
- 4 Check for excessive re-circulation of heated air from rear to the front, use in a fully enclosed rack installation is not recommended.
- 5 If possible shutdown the enclosure and investigate the problem before continuing.
