Deploy OCP form-factor network and acceleration cards into Blowig Rock servers without custom chassis changes. The OCP Option Kit (MPN 4XC7A90107) provides the mechanical and electrical interface required to accept OCP mezzanine modules, ensuring correct alignment, retention, and thermal clearance inside the server bay. Specifying the Lenovo kit eliminates compatibility guesswork and shortens deployment timelines by aligning procurement with Lenovo service and spares processes. For teams migrating to OCP NICs, offloading network or security functions, or adding FPGA-based acceleration, the kit delivers a repeatable integration path that reduces rack-level disruption and operational variance compared with DIY adapters.
