You have attempted to reboot or clear service tracks without submitting a valid IP address for the processor card. You must enter a valid IP address for the processor card on which you are trying to perform the task. If you are attempting to reboot a processor card, you must enter the valid IP address for that processor card. If you are attempting to reboot the enclosure (both processor cards), you can enter a valid IP address for one of the processor cards in the enclosure.
Ensure that you enter a valid processor card IP address, and resubmit the task.
