Product Details

The warm failover feature requires an INNPM11 module with firmware revision level C_0 or later and an NKMP01 or NKMP11 cable. While the cabinet is powering up or whenever a backup NPM module is inserted into the module mounting unit, the two redundant NPM modules arbitrate for the primary and backup roles. This arbitration takes place over the Controlway. When the primary and backup roles are established, the backup module requests an image of the dipswitch settings of the primary NPM module. This image is transferred over the Controlway. All further redundancy communication takes place over the NKMP01 and NKMP11 cable. Warm failover requires the primary NPM module to transfer a copy of its database of node, module, block, and exception report route records to the backup NPM module. On warm failover, the new primary NPM module broadcasts a warm failover node restart broadcast message on the loop and immediately obtains new exception reports from control modules in its node. These exception reports are sent to all nodes that have established exception report routes to the former primary NPM module. Other nodes that recognize the warm failover restart broadcast message will send the new primary NPM module updated exception reports for all points that the former primary NPM module requested. In this way the new primary NPM module transfers updated exception reports .
