FAQs

Q: What DC input range is supported?
A: Typical operating range is -40 to -72 VDC with -48 VDC nominal.

Q: Is the PSU hot-swappable?
A: Yes, it can be swapped without shutting down the switch.

Q: What does B2F airflow mean?
A: Back-to-front airflow moves air from the rear toward the front (port side), aligning with front-exhaust designs.

Q: Can I pair this DC PSU with an AC PSU for redundancy?
A: No. Both PSUs should be the same type and airflow orientation for proper operation.

Q: Does this require an external RPS?
A: No, it is a self-contained PSU; a second matching PSU provides redundancy if desired.
