Fujitsu PRIMERGY RX2540 M4 24x 2.5-Inch Chassis Upgrade Kit (from 8x) S26361-F2495-L424

When a Fujitsu PRIMERGY RX2540 M4 server in a colocation rack starts hitting its storage ceiling, this chassis upgrade kit is the direct fix. It swaps the standard 8-bay 2.5-inch backplane for a 24-bay unit, tripling local drive capacity without changing the server's 2U footprint. The kit includes the backplane, all necessary cables, and drive cages/trays, making it a complete internal expansion solution.

Ideal use cases

• Scaling storage for virtualized environments (VMware, Hyper-V)
• High-capacity backup or archive servers
• Database servers requiring large local disk pools
• Software-defined storage (SDS) nodes
• Upgrading existing RX2540 M4 servers in colocation facilities

Good to know

This upgrade is intended for servers originally equipped with the 8x 2.5-inch drive configuration. Verify your server's current backplane before installation. The kit is designed for internal use and requires the server to be powered off during installation.
