Product Short Description
The GE VMIVME-7452 is a 6U single-slot VMEbus storage module designed for embedded industrial systems. It provides flexible, high-reliability mass storage options—integrating a 3.5-inch hard disk drive (HDD), a 3.5-inch floppy disk drive (FDD), or both, with an optional flash memory upgrade. As a passive VMEbus board, it draws power directly from the VMEbus backplane, eliminating the need for external power supplies. It serves as a dedicated storage expansion for GE VMIC VMEbus single-board computers (SBCs) in critical industrial control and data logging applications.

Functional Overview
The VMIVME-7452 functions as a dedicated storage expansion for VMEbus embedded systems. It connects to the VMEbus backplane via the P2 connector, drawing +5 V power and providing direct access to HDD, FDD, or flash media. The passive design ensures minimal power consumption and heat generation, while the rugged construction withstands harsh industrial conditions. By combining legacy floppy support with modern HDD/flash options, it enables seamless data storage, system backups, and legacy media access for VMEbus-based control and monitoring systems.
