The Control Board is responsible for system management in a QFX10008 or QFX10016
(see Figure 17 on page 27). The switch chassis can run with one or two Control Boards.
Base configurations ship with one Control Board that can be expanded with a second
Control Board for a fully-redundant system. When two Control Boards are installed, one
functions as the master and the second as a backup. If the master Control Board is
removed, the backup restarts and becomes the master.
