Fans

The SYS-822GS-NBRT server supports 12 heavy-duty fans with optimal fan speed control.

Fan speed is controlled by a system temperature setting in the BMC. If a fan fails, the remaining fans will ramp up to full speed. The system can continue to run with a failed fan. Replace any failed fan at your earliest convenience with the same type and model. Failed fans can be identified through the BMC.

Important: Except for short periods of time, do not operate the server without the cover in place. The chassis cover must be in place to allow for proper airflow and to prevent overheating.

Changing a Rear Fan

1. Inspect the fans to see which has stopped.

2. After determining which fan has failed, remove the system from the rack and place the system on a workbench.

3. Simultaneously squeeze both release tabs on the front of the fan to be replaced and pull the fan from the chassis.

4. Insert a new fan back into the vacated fan bay and make sure that it is fully seated.

5. Power on the system to confirm that the fan is working properly. When you've determined the fan is working, turn off power to the system and remove the power cable.

6. Return the system to the rack.

7. Reconnect the power cable to the system and resume normal operation.
