Alarm Information
Handling Process
• Split a stack established using service port connections.
1.        Run the save command to save the configuration.
2.        Run the copy source-filename destination-filename all command to back up the configuration file to all the member switches.
Back up the current configuration file to all the member switches before you split the stack. You can use the configuration file when you set up a stack next time.
3.        Remove stack cables between the member switches. After you remove stack cables, the stack splits and some member switches restart. The remote login may fail because some configurations of member switches such as the IP address are the same. Log in to a switch through the console port to perform configurations.
4.        Run the system-view command to enter the system view.
5.        Run the interface stack-port member-id/port-id command to enter the logical stack port view.
6.        Run the shutdown interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10> command to disable physical member ports.
7.        Run the undo port interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10> enable command to restore physical member ports to service ports.
8.        Run the quit command to exit from a logical stack port.
9.        Run the stack slot slot-id renumber 0 command to restore the stack ID of a member switch to the default value 0.
10.        Power off all the member switches.
