Dell R740xd Mid plane 4x 3.5" Backplane | PNXRX

The Dell PowerEdge R740xd 4x 3.5" Mid-Plane Backplane (Part Number: PNXRX) is designed to connect up to four additional 3.5-inch SAS or SATA drives installed in the mid-bay area of the server chassis. This component interfaces between the drives and the system’s storage controller, supporting internal expansion of storage capacity for data-heavy environments.

This backplane is installed in the mid-chassis region of the R740xd and works in conjunction with other required components such as cables and drive trays. It does not support hot-plug drive replacement on its own. Any maintenance or installation involving drives connected to this backplane should be performed with the system powered down to prevent data loss or hardware issues.
