As the fault is generated when the two controllers are powered on simultaneously, it is recommended to power on one controller a time:
Step 1 Power on one controller.
Step 2 After the controller is powered on, connect the PC to the S5300 with the serial port cable and open the HyperTerminal. Run the chgctrlip -c A [here controller A is used as an example] -a 172.16.16.23 [changed according to the site situation or customer’s requirement] -g 255.255.255.0 -s 172.16.16.254 command to change the IP address of the controller. Log in to the OSM and synchronize the controller time with the system time.
Step 3 Power on the other controller, and then the system automatically synchronizes the time.
The information displayed on the HyperTerminal and OSM indicates that the two controllers are powered on.
