Reverse Airflow PSU for S4048-ON
The Dell 3HC75 is a rack-mount power supply designed for reverse airflow, moving air from the PSU side toward the I/O ports. It is built for network environments that require this specific cooling direction.
Network engineers using compatible Dell switches
This unit suits administrators deploying or maintaining the listed Dell switches that require PSU-to-I/O airflow. It is not for operators whose chassis demand front-to-back or I/O-to-PSU airflow direction.
PSU-to-I/O reverse airflow direction
The defining specification is the reverse airflow path, which must match the switch chassis design. Installing a unit with the wrong airflow orientation will compromise thermal management.

คำถามเกี่ยวกับสินค้านี้
How often does the internal fan in the 3HC75 need replacement under continuous operation?
The 3HC75 uses a sealed fan module rated for long-life operation; no user-serviceable schedule is published.
What thermal limit triggers throttling on the 3HC75 when the S4048-ON runs at full load?
The unit relies on the switch chassis thermal sensors; it has no independent throttle point.
What is the typical acoustic output of the 3HC75 when the S4048-ON runs 24/7?
Reverse airflow moves heat toward the I/O side; noise matches the switch fan curve at equivalent RPM.
