eX 822A Central Processing Card 2
The eX 822A works as a hot-standby Central Processing Card (CPC) for the eX 821A. The module slots into a dedicated slot in the eX 802A Dual CPC Main Frame and monitors the operation of the primary CPC. In the event of failure to the primary CPC, the secondary CPC will automatically take over the entire operation. The switchover is instantaneous while an audible warning is emitted in the event of failure for rectification work. Every event is logged for reporting and available for print-out from the GUI.
