Thermal warnings

If the OPS panel System Fault LED and Logical Fault LED are ON and all drive LEDs are

flashing or an audible alarm sounds continuously and cannot be muted, this may signal a

thermal warning.

This can happen when one of the following occurs:

• The enclosure temperature is at a higher threshold than the thermal alarm. (This should

already have been activated).

• All fans have failed.

• Only one fan is operating and the internal temperature is 40°C (104°F) or above.

If this occurs, take the following actions:

• Switch off immediately.

• Check for airflow restrictions.

• Check power supply module faults.

• Check for excessive local temperatures.
