Product Description
IBM EJ19 PCIe3 cable adapter
The IBM EJ19 PCIe3 Cable Adapter (CCIN 6B53, part number 02AE929) is a specialized PCIe Gen3 x8 host-side adapter designed for IBM Power Systems servers. This low-profile card provides the necessary PCIe-to-SAS bridging and cable interface to connect the server to PCIe3 I/O expansion drawers or SAS storage enclosures via external optical or copper cables, enabling scalable I/O expansion (additional PCIe slots, NVMe SSDs, NICs, HBAs) for AIX, IBM i, Linux, and VIOS environments in Power8, Power9, and select Power10 configurations.
Product Description
The IBM EJ19 (feature code EJ19, CCIN 6B53, part number 02AE929) is a PCIe Gen3 x8 cable adapter that installs in a host server PCIe slot and serves as the connection point for external PCIe3 expansion cabling. It features a Mini-SAS HD (SFF-8644) port (or compatible connector) to attach to optical AOC cables (e.g., ECC8 pair) or copper DAC cables, extending PCIe Gen3 x8 bandwidth (up to 64 Gbps aggregate) to remote PCIe3 I/O expansion drawers (#ELMX, #ELMY, #ELMZ, #ELC1, #ELC2) or compatible SAS enclosures. The adapter includes retimers and signal conditioning for reliable long-reach connectivity (up to 10 m with AOC). It is IBM-qualified for low-latency, high-throughput I/O expansion in Power Systems, supporting additional PCIe adapters, NVMe storage, networking, or storage HBAs without consuming extra host slots. The EJ19 is a critical component for high-density virtualization, large databases, AI/ML training, and mission-critical workloads requiring remote drawer placement on AIX, IBM i (iSeries/AS/400), Linux, and VIOS platforms.
