FUJITSU S26361-F3846-L32 Riser Card Left — Server Expansion Interface

Fujitsu left riser card S26361-F3846-L32 is an expansion component designed for the PRIMERGY RX2540 M4 server. It provides additional PCI Express slots to increase the server's I/O capacity and accommodate add-in cards for networking, storage controllers or other peripherals. The module matches the form factor and compatibility requirements of the Fujitsu PRIMERGY RX2540 M4 system.

Advantages

The riser card offers a compact, system-specific expansion solution that preserves server bay layout while adding one full-height PCIe 3.0 x8 slot and one full-height PCIe 3.0 x16 slot. It supports low-profile compatibility for one x16 slot and is manufactured to Fujitsu specifications to ensure proper fit and electrical compatibility with the PRIMERGY RX2540 M4.

Suitable for

• Adding network interface cards (NICs) to the PRIMERGY RX2540 M4
• Installing storage controller or RAID cards
• Expanding GPU or accelerator connectivity within supported power and cooling limits
• General PCIe expansion for custom I/O requirements in the server
