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 Master Select 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. If the problem
is still not resolved, contact your dealer for assistance.
