PCIe riser card FUJITSU PY-PRE853 FH Slots x8 Right for server/motherboard expansion

FUJITSU PY-PRE853 is a PCIe riser card engineered to add a full-height PCI Express x8 expansion slot in supported Fujitsu server and motherboard configurations. The card installs to the right of the motherboard mounting area to reposition a PCIe x8 interface, allowing installation of standard full-height expansion cards where space constraints or chassis layout previously prevented it. The riser is intended for use in compatible Fujitsu systems to enable additional I/O, storage controllers, network adapters, or accelerator cards without major chassis modification.

Advantages

The riser provides a straightforward mechanical and electrical solution for relocating a PCIe x8 slot, conserving internal space while maintaining full-height card compatibility. It supports plug-and-play installation on systems that explicitly list this riser as supported, preserving signal integrity for x8 PCIe lanes and avoiding custom cabling. Using a dedicated riser designed for Fujitsu systems helps ensure correct alignment, secure mounting, and compatibility with chassis brackets and retention mechanisms.

Suitable for

• Upgrading servers with additional network interface cards or storage controllers
• Replacing or adding PCIe cards in confined chassis where direct motherboard mounting is not possible
• Deploying accelerator or offload cards in rack servers with limited internal clearance
• System refurbishment and component reconfiguration in datacenter hardware

Key specifications

• PCI Express form factor: full-height expansion slot
• Electrical interface: x8 PCIe lane configuration
• Mounting orientation: right-side installation relative to motherboard mounting points
• Compatibility: designed for supported Fujitsu server/motherboard models
• Typical use environment: server and workstation chassis with constrained internal layouts

How to use

Power down the system and disconnect power and all external cables before commencing installation. Remove the appropriate chassis cover and locate the motherboard mounting area or riser slot designated for this adapter. Align the riser card with the mounting points and secure it according to the chassis and motherboard instructions, ensuring the full-height bracket and retention clips are correctly seated. Install the desired PCIe x8 card into the riser slot, then reassemble the chassis, reconnect power, and verify that the system recognizes the installed hardware through the system firmware or operating system device manager.

Recommendations

Confirm system compatibility in Fujitsu documentation or support resources before purchasing. Use static-safe handling and follow the server manufacturer’s service manual for installation steps, torque limits, and any BIOS or firmware updates that may be required for proper hardware recognition.
