Procedure
Step 1 Run the display board frameid/slotid command to query the board information, and then check
whether the configured board type is the same as the one in use.
l If the configured board type is the same as the one in use, go to Step 3.
l If the configured board type is different from the one in use, replace the current board with
one configured in the system. Then, go to Step 2.
l Conversely, if the configured board type is different from the one in use, run the board
delete frameid/slotid command to delete the board type configured in the system if the
board type configured in the system is incorrect, and then run the board confirm frameid/
slotid command to confirm the board once the system automatically detects the board. Then,
go to Step 2.
Step 2 Wait five minutes. Then, check whether the fault is rectified.
l If the fault is rectified, go to Step 11.
l If the fault persists, go to Step 3.
Step 3 Check whether the ambient temperature of the device is too high.
NOTE
A board repeatedly resets if its ambient temperature is too high.
l If the ambient temperature of the device is too high, go to Step 4.
l If the ambient temperature of the device is normal, go to Step 5.
Step 4 Run the fan speed command to adjust the fan speed on the device to improve ventilation effect,
or add cooling equipment to ensure that the device works in a proper ambient temperature. Then,
check whether the fault is rectified.
l If the fault is rectified, go to Step 11.
l If the fault persists, go to Step 5.
Step 5 Check whether the board is properly installed.
l If the board is properly installed, go to Step 7.
l If the board is not properly installed, install the board properly, and go to Step 6.
Step 6 Check whether the fault is rectified.
l If the fault is rectified, go to Step 11.
l If the fault persists, go to Step 7.
Step 7 Replace the board with a new one, wait about five minutes, and then check whether the new
board repeatedly resets.
l If the new board repeatedly resets, go to Step 8.
l If the new board does not repeatedly reset, go to Step 11.
Step 8 Run the display io-packetfile information command to query the information about board
software packages in the flash memory and then check whether the information contains the
board software package information and whether its version is correct.
l If the information contains the board software package information and its version is
correct, go to Step 10.
l If the information contains no board software package information or its version is
incorrect, go to Step 9.
