Applications
The Nortel Meridian 1 was one of the most widely deployed enterprise PBX platforms of the 1990s and 2000s, used by large corporations, government agencies, universities, and healthcare organizations worldwide. Power regulator boards like the NT6D81AA are internal infrastructure cards that condition and distribute DC power to the cards housed in a Meridian 1 shelf or superloop. Maintaining a stock of these boards is essential for organizations still running Meridian 1 systems, as a failed power regulator can take an entire shelf of line cards offline. Replacement and spare boards for the Meridian 1 platform remain in demand among telecom technicians maintaining legacy PBX infrastructure.
This Nortel Meridian NT6D81AA Power Regulator Board has been visually inspected and appears to be in good used condition. The PCB is clean with no visible cracks, burn marks, or damaged components, and the card edge connectors look intact. The board dates from 1993 (date code 93 39) based on the label visible on the board. It was pulled from a working environment where it was previously in service.
