Nortel NTFN33DA Passport Control Processor 2 (CP2) module with EIDE disk.
The Nortel NTFN33DA is a Passport Control Processor 2 (CP2) module fitted with an EIDE disk, used in Nortel’s Passport 6400/7400/8000-series data switching platforms.
The CP2 card provides the control-plane processing for the Passport shelf, running the switch’s operating software and managing configuration, routing and system control functions, with the onboard EIDE disk holding the software image and configuration data. It is part of the same control processor family as the NTFN33BD (Passport 6480) and NTFN33GA/HB variants used across related Passport shelves.
The NTFN33DA is specific to Nortel’s Passport switching platform. Tech-Star (UK-based, shipped worldwide) checks every card before it ships. Get in touch to confirm compatibility with your Passport shelf and software release.
