    Redundancy backup

    Supported

    Main control board is mandatory for switches. Each switch must be configured with one or two main control boards. When one main control board is configured for a switch, the main control board can be installed in either main control board slot of the switch. When two main control boards are configured, the two main control boards work in hot standby mode to improve reliability of the switch. The active and standby main control boards monitor the status of each other. If the active main control board fails, the standby main control board automatically becomes active to ensure uninterrupted services.

    Hot swapping

    Supported

    Before removing the active EH1D2MCUAC00 card, perform an active/standby switchover.
