Nortel DS1404025 (OPTera Metro / PDH-SDH / Passport-MSS / networking portfolio) Datacentre Switch

The Nortel DS1404025 is a Passport 8691SFMZ Routing Switch Module, the CPU and switch-fabric module for the 8691SF variant of Nortel’s Passport/Accelar 8000-series routing switch chassis. It provides the central processing, switch-fabric and management functions the chassis’s interface modules rely on, and is required for the chassis to route or switch traffic at all; without a working CPU/switch-fabric module the chassis’s other cards cannot pass traffic. Passport 8000-series chassis remain deployed as core and distribution-layer switching platforms in many established enterprise and carrier networks. Confirm the exact chassis model, since the 8690SF and 8691SF CPU modules are not always directly interchangeable, and matching memory upgrades may be required for later software releases. Tech-Star (UK-based, shipped worldwide) stocks Nortel spares to support ongoing network maintenance and expansion projects. Contact our sales team for current availability.
