Dual 750W AC power-supply kit

This Dell 450-AESE kit provides two 750W AC power supplies and five matching fans for compatible networking switches. All units deliver reverse airflow from PSU toward the I/O side. The package is sold new with firmware already updated.

Networking teams standardising on S4248FB-ON.

The kit fits directly into those three Dell Networking models and replaces or populates both PSU bays. Builders using different switch chassis, front-to-rear airflow requirements, or DC-input power cannot use this kit.

Reverse airflow direction (PSU to I/O)

Cooling air moves from the power-supply side toward the port side, so the rack layout must support that path. If the installation requires front-to-rear or side-to-side airflow, this kit will not match the thermal design.

Vragen over dit artikel

Which Dell switches must I already have installed to use this 450-AESE conversion kit?

The kit is compatible with Dell Networking S4248FB-ON, S4248FBL-ON and Z9100-ON switches, so one of those models must be present in the rack.

If I keep my existing forward-airflow fans, will the two 750W AC reverse-airflow PSUs in this kit operate correctly?

No, the PSUs use reverse airflow from PSU to I/O, so all five included X3WCP reverse-airflow fans must be installed to maintain the proper cooling direction.

After fitting both R17R1 power supplies and all five X3WCP fans, what indicates the kit is functioning as intended?

Both PSUs should show green status LEDs and the switch management interface should report both power supplies and all five fans as present and operating normally.
