switch.
Clear the EXTRA-TRAF-PREEMPT Alarm
Step 1 Verify that the protection switch has occurred by checking the Conditions tab.
Step 2 If a ring switch has occurred, clear the ring switch on the working system by following the appropriate
alarm in this chapter. For more information about protection switches, refer to the “2.9.2 Protection
Switching, Lock Initiation, and Clearing” section on page 2-262 or the “Maintain the Node” chapter in
the Cisco ONS 15454 Procedure Guide.

switch on the working system.
Step 4 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
