Abstract
An apparatus comprises a switch and nodes coupled to the switch. Each node does not include an integrated video controller and transmits data to the switch via a USB and a serial connection. The switch comprises a controller which stores video output generated based on data received via serial connections. The controller: receives a user selection for a first node; transmits the user selection to a first multiplexer; retrieves a first video output generated based on data received via the corresponding serial connection; and transmits the first video output to a second multiplexer. The first multiplexer transmits USB data received from the first node to the second multiplexer. If the first node is in a pre-boot environment, the second multiplexer selects the first video output for transmission. If the first node is in a post-boot environment, the second multiplexer selects the data received from the first node for transmission.
