    • For IBM AS400 Older Models

    IBM Expansions for Older AS/400 Models - PCI-X Towers & Storage Units

    Discover reliable expansion solutions for older IBM AS/400 and early iSeries systems. These PCI-X towers, storage expansion units, and I/O enclosures add disk bays, PCI slots, and I/O capacity to support legacy workloads in OS/400 environments. Designed for rack or tower setups, they connect via SPD, RIO/HSL, or direct attachment for enhanced scalability on classic AS/400 hardware.

    Why Choose Expansions for Older AS/400 Models?

    Older AS/400 systems (e.g., Models 500/510/530, 270, AS/400e 7xx, migration from 640/S30/730) benefit from modular expansions to increase storage and PCI/PCI-X adapter capacity without replacing core hardware. PCI-X towers (0595/5095) provide disk bays and slots, while storage units (505x series) add high-capacity disk options. These expansions support Ultra SCSI/Ultra2 SCSI interfaces, hot-swap where applicable, and integrate via SPD or RIO/HSL for redundancy and growth. Ideal for maintaining legacy OS/400 applications requiring expanded I/O and storage.

    Available IBM Expansions for Older AS/400 Models

    • IBM 5074 PCI Expansion Tower HSL Feature Code: 5074 PCI expansion tower with 45 disk slots, 14 PCI slots, and two removable media bays. HSL-attached for high-performance I/O on compatible older models.
    • IBM 5075 PCI Expansion Tower Feature Code: 5075 PCI expansion tower with 6 disk slots and 7 PCI slots, includes 32MB PCI IOP. Compact I/O addition for Model 270 and similar legacy systems.
    • IBM 0588 PCI-X Expansion Unit in Rack Feature Code: 0588 Rack-mounted PCI-X expansion unit with 14 PCI-X slots (equivalent to #5088 in #0551 rack). Adds adapter capacity for older AS/400 systems.

    Note: These expansions primarily use PCI-X, SPD, and Ultra SCSI/Ultra2 SCSI technology. Compatibility varies by model (e.g., Models 500/510/530, 270, AS/400e 7xx). Always verify exact cable/controller requirements for your specific legacy AS/400 model.

    Compatibility & Support

    These expansions are compatible with older IBM AS/400 and early iSeries systems, including but not limited to Models 500, 510, 530, Model 270, AS/400e 7xx series, migration from Models 640, S30, 730, and compatible racks, towers, and configurations.
