The VW-CPU can be installed in the ATEN VW3620 36 x 20 Modular 4K Video Wall Processor, which features two CPU board slots. The upper slot is running as the primary by default. Each VW-CPU is equipped with an individual 10/100/1000Base-T LAN port and controller card which enables efficient transmission and management of data. VW-CPU comes hot-standby that standby CPU will automatically backup and switch as primary to resume the logic workings and IO control from the previous stopped when the primary CPU shuts down. It can take over the primary system operation immediately to guarantee easy maintenance of interface via Web GUI without shutting down the current display on the video wall. Consequently, VW-CPU supports redundancy to ensure uninterrupted operation for any mission-critical video wall applications.
