Functions

Why "Golden" MI Cards Matter

Used Ciena/Nortel MI Cards are often “tarnished” and cannot be reused without a software reset and reload. During installation, the card commits itself to a rack and deletes unused software loads, preventing reuse.

Golden MI Cards are new or factory‑reprogrammed for full functionality and network safety.
