Nortel AL2033010 (OPTera Metro / PDH-SDH / Passport-MSS / networking portfolio) Telecom System Card / Module

The Nortel AL2033010 is a 400-ST1 Cascade Module for Nortel’s Business Policy Switch 2000 (BPS2000) stackable switch range. It fits the BPS2000’s dedicated cascade module bay and provides the high-speed stacking link used to join multiple BPS2000 units into a single logically-managed switch stack, distinct from the unit’s regular Ethernet uplink ports. A working cascade connection is what lets a BPS2000 stack share configuration, spanning-tree state and management as one device rather than several independent switches. Confirm the exact BPS2000 hardware revision before ordering, since Nortel’s cascade module family changed across the platform’s production run. BPS2000 stacks remain deployed at the network edge in many established installations, and this cascade module is a routine spare for maintaining or extending an existing stack. Tech-Star (UK-based, shipped worldwide) carries Nortel components for engineers maintaining legacy and transitional network installations. Contact our sales team for availability.
