Stack Troubleshooting
If a stack fails to initialize or function, first check the following items:
• Check that all stacking cables are properly connected.
• Check if any stacking cables appear damaged.
• Check that only one Stack Master button is pressed in.
• Check that all switches in the stack are powered on.
After checking all items, reboot all the switches in the stack.
The switches allow you to configure ring- or line-topology stacking. When using
ring-topology stacking configuration and a switch fails, or a stacking cable is
disconnected, the entire stack reboots and resumes normal operation using
line-topology stacking through the remaining stack connections. Also, any changes
to the stack including powering down of a unit or the insertion of a unit causes the
stack to reboot.
