The Siemens S42024-D3542-A202 is the LAD board, the alarm and hard disk card for the Siemens TransXpress SMA 1/4 SDH transmission system, later sold under the Nokia Siemens Networks name. The LAD handles the alarm interface and the disk storage the shelf uses for its software and its configuration, so it sits alongside the traffic cards rather than carrying traffic itself, and a failure on it costs the shelf its alarm reporting rather than its circuits. Boards of this type are also found with a further trailing suffix after the A202, such as 13, 06 or 11, so check the suffix on the card being replaced. Tech-Star (UK-based, shipped worldwide) supplies Siemens transmission components for ongoing maintenance projects.
