Nortel AL2012A15 BayStack/Ethernet Routing Switch networking and Meridian/DMS-100 telephony Datacentre Switch

The Nortel AL2012A15 is a BayStack 450-12T stackable Ethernet switch, providing 12 10/100Base-TX ports plus two expansion slots for uplink or stacking modules. The BayStack 450 range was Nortel’s high-density wiring-closet switch family, built for fail-safe stackability across multiple units alongside advanced traffic-management features including VLAN trunking, priority queuing, IGMP snooping, MultiLink Trunking and RMON support on every port. It sits in the same BayStack switching lineage as the smaller 310-series and other members of this listing, differing primarily in port count and expansion capability. BayStack 450 switches remain in service in enterprise wiring closets that have not been refreshed to newer switching hardware, and genuine units are needed to maintain existing stack capacity or replace a failed switch without disturbing the rest of a stack. Confirm your existing stack’s firmware revision before adding a replacement unit. Tech-Star (UK-based, shipped worldwide) stocks Nortel BayStack components to support ongoing network maintenance projects.
