650W DC Power Supply for QFX5100-48T

This 650 watt DC power supply is built for the QFX5100-48T switch chassis. It fits standard ATX bays and ships in new condition. The unit has been tested working to confirm reliable operation.

Capacity and headroom for 48-port switches

The 650W rating delivers enough headroom for a fully populated 48-port configuration under typical loads. It will run out of capacity if the chassis draws sustained power above the rated output or if redundant units are not installed for failover.

Questions about this item

Will the 650W DC unit fit the same slot and connector layout as the original supply in my QFX5100-48T?

Yes, the JPSU-650W-DC-AFI is built to the exact form factor and pin-out used by the QFX5100-48T, so it slides into the existing bay and mates with the native DC input without adapters.

What should I check on the switch front panel to confirm the new 650W supply is operating correctly?

After power-on, the QFX5100-48T front-panel PSU status LED should show steady green and the CLI command "show chassis environment pem" must report the supply as "Online" with normal voltage and temperature readings.
