Aastra ROF1376303/1 – DC/DC MX-One Board

Overview

The Aastra ROF1376303/1 DC/DC MX-One Board is a dedicated power supply and DC/DC conversion board intended for Aastra MX-ONE telephony systems and compatible Ericsson/Mitel implementations. It converts and regulates internal 48VDC power to support stable telephony system operation, supplying core modules within the MX-ONE architecture.

Seven Star LLC supplies the Aastra ROF1376303/1 and related MX-ONE telephony hardware to enterprise communications projects across Oman and the GCC, with compatibility checks and expert support for existing PBX installations.

Operating Principle

The board takes internal 48VDC system power and performs DC/DC conversion to deliver correctly regulated voltage to the telephony modules it supplies within the MX-ONE chassis. Stable, regulated power at this stage of the system’s internal power architecture is what keeps core telephony processing modules operating without the voltage fluctuations that could otherwise cause resets, call processing errors, or degraded system reliability.

Because the board typically operates within MX-One Lite (3U chassis) and similar subrack modules, it forms part of a redundancy-capable power architecture where enterprise telephony systems require continuous, high-availability power distribution rather than a single point of power failure.

Engineering Design of the ROF1376303/1

Manufactured in Germany by Aastra/Ericsson, the board is built to the OEM specification of the MX-ONE Lite/Slim/Classic series, ensuring correct fit and electrical compatibility within the chassis it is designed for. It is supplied with a 1-year warranty, giving telephony system integrators confidence in its performance and reliability for professional communications environments.

As a genuine OEM component rather than a generic power board, the ROF1376303/1 is matched precisely to the MX-ONE system’s internal power distribution requirements, which matters for maintaining the reliability the platform is designed to deliver in continuous-uptime enterprise telephony deployments.
