HP 5064-1965 5064-1948 LXR Pro System Management PCBA ISA Card SMB I2C

The HP 5064-1965 (HP Manufacturer P/N 5064-1948) is the LXR Pro System Management card for HP's LXR Pro server platform. This ISA-bus PCBA provides SMBus (I2C) system monitoring and remote management connectivity, allowing the server chassis to track subsystem health and communicate management data between internal components and an external management interface via the EXT I2C port on the bracket.

Applications

The LXR Pro System Management card is designed for HP's LXR Pro rack-optimized server line from the mid-to-late 1990s. System management cards of this type sit on the ISA bus and act as the bridge between the server's internal SMBus (I2C) monitoring network — covering temperature sensors, fan controllers, and power rails — and the external management interface. They were a standard fixture in enterprise server architectures of the era before IPMI became the dominant out-of-band management standard, giving data center operators the ability to monitor chassis health, respond to alerts, and in some configurations support remote access without relying on the host OS. This card would be sought by anyone maintaining, repairing, or restoring an HP LXR Pro server system.
