Description

Tri-slot PCIe riser delivering two x8 and one x16 Gen5 lanes from the second CPU path to expand I/O in dense 2U platforms. Ideal for high-bandwidth NICs, HBAs, or accelerators, balancing lanes across processors for optimal throughput. Targeted compatibility with C240 M8 configurations using Riser 2A on the CPU2 side.

Features

- Expands I/O with three Gen5 PCIe slots on the CPU2 side
- Balanced lane distribution across processors for higher aggregate bandwidth
- Backward compatibility with existing PCIe Gen4/Gen3 ecosystem
- Optimized for dense 2U configurations
- Tool-less/low-touch installation in compatible chassis

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Does this require the second CPU to be installed?
A: Yes, it sources lanes from CPU2.

Q: Will it work in M7 platforms?
A: Use the corresponding M7 Riser 2A variant.

Q: Can I use Gen4/Gen3 cards?
A: Yes, the slots are backward compatible at the add-in card’s max speed.

Q: Are mounting screws/brackets included?
A: Riser hardware typically uses the chassis’ integrated mounts; separate card brackets ship with the add-in cards.

Q: Any special licensing needed?
A: No software license is required for the riser itself; observe platform power/thermal limits.
