My 7507 router has the following problem,and i don't know that if it was a malfunctioned CI problem or a power supply problem.How can i trouble it?

Accoriding to my previous experience,the CI model in 7507 router is easy to report the +12V voltage at a low level,and there is something wrong with the ci model.
