    4. Check the RJ45 port on the panel of the PMU. The RJ45 port should be connected to the RS232 port and the RS422 port. (You are recommended to the connect the cable to the port on the left.)
    5. Check whether the alarm is cleared:

      Y => The alarm is cleared. No further action is required.

      N => The alarm is not cleared. Go to step 2.

  2. Check whether the heat exchanger board communication alarm is generated on the BSC side.

    Y = > The alarm is generated. Replace the UPEU board (the MON port is faulty). Check whether the alarm is cleared:

    Y => The alarm is cleared. No further action is required.
