Huawei CN21SWIA0 Main control board function; 2.5 Tbit/s switching bandwidth; T8280-based core-network chassis Telecom System Card / Module

The Huawei CN21SWIA0 (SWIA0) is a main control board used in the Huawei T8280-based family of ATCA core-network chassis, which underpins several Huawei carrier platforms sharing the same subrack architecture (including USN9810 and MSOFTX3000 family systems). The board manages system operations and facilitates high-speed internal data switching, with a switching bandwidth of up to 2.5 Tbit/s, supporting applications such as VoBB (Voice over Broadband), PSTN interworking and Convergent Conference Solutions running on the same chassis. As a main control board it plays a central role in coordinating the other service and interface boards fitted into the shelf. It is stocked as a like-for-like maintenance spare for operators keeping an existing T8280-family chassis running rather than replacing the platform outright. Tech-Star (UK-based, shipped worldwide) supplies this board tested and ready to deploy – get in touch to confirm stock and compatibility with your chassis.
