Ericsson ROF1377942/4 Winchester disk storage module for Ericsson MD110 / MX-ONE telecommunications switching systems.

The Ericsson ROF1377942/4 is a Winchester disk storage module (marked WINCHSTR DSK) used within Ericsson MD110 and MX-ONE telecommunications switching systems. ‘Winchester’ refers to the sealed hard disk drive technology standard in enterprise computing equipment from the late 1970s through the 1990s, and this module provided the mass storage used for holding the exchange’s system data, configuration and software.

Within an MD110 or MX-ONE installation, the disk store works alongside the processor and program store hardware to retain call records, subscriber data and system software between power cycles. As electromechanical hard disk technology, these modules are a common failure point in ageing MD110 installations, making working replacement units a sought-after spare.

This is a legacy, no-longer-manufactured Ericsson component, supplied as a maintenance or replacement part for operators keeping older MD110 or MX-ONE systems running. Tech-Star (UK-based, shipped worldwide) stocks new and refurbished Ericsson telecommunications hardware. Enquire for current availability, condition and price.
