    Products
    DFE
    Firmware 5.11.29 and lower
    7C111

    Changes
    Installed DFE blade into N1 chassis

    Symptoms
    Won't boot
    Red CPU LED

    Cause
    DFE modules require firmware version 5.12.02 or higher to work properly in a 7C111 chassis.

    When a DFE module with an earlier version of firmware is installed, the module will not boot, and will display a red CPU LED.

    Note: The 7C111, aka the "Matrix N1", is a one-slot DFE chassis with two integrated power supplies and six integrated fans. The only modular aspect is the single DFE blade supported.

    Solution
    Upgrade to firmware 5.12.02 or higher.

    Since the module is not fully operational in the 7C111 chassis, this will require using the serial download (Zmodem) method or temporarily moving the module to a multi-slot support chassis to perform a TFTP/FTP download (5040).

    The Zmodem upgrade procedure is explained in the "Downloading via the Serial Port" section of the Matrix DFE Series Configuration Guide.
