Questions about this item

What form factor does the DPR2900B-48 power supply use for mounting?

The unit follows the ATX form factor, so it fits standard ATX mounting points and cut-outs in compatible chassis or rack trays.

What is the correct orientation when installing the ESR-48/56B F module in a rack?

Slide the module in until the front latch clicks; the fan must face the airflow channel — reversing it blocks cooling and causes thermal shutdown.
