Are Power Modules and Fan Modules of CloudEngine 8800, 7800, 6800, and 5800 Series Switches Interchangeable?

Are Power Modules and Fan Modules of CloudEngine 8800, 7800, 6800, and 5800 Series Switches Interchangeable?

Power modules and fan modules of CloudEngine 8800, 7800, 6800, and 5800 series switches are not interchangeable. A switch must use the power modules and fan modules matching its model. The following table lists the power modules and fan modules applicable to different CloudEngine 8800, 7800, 6800, and 5800 models and version support for these modules.

If the CloudEngine 8800, 7800, 6800, and 5800 series switches use power modules that do not match their product models, the switches generate an alarm and may be powered off due to power shortage.

When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used. Type-B power modules can only be used with type-B fan modules and cannot be used with type-F fan modules.
