If you have power supply M-type PSLP1433 try replacing with another

The CPU boots and restarts again without powering the line cards.could it be the CPU, memory card or power?

If it blinks on red during booting,
It Will still reboot again on red.it doesn't enter to run.it continually Binks in red.

Is the sd card led flashing or just one or two flicks

Have you tried to read the sd card to see if it is readable

 

[Alex_2021]

Its flashing..

Remove CPU card from PBX , with a small screwdriver (or something similar) pull out pin B42 4-5 mm, return CPU into PBX

I have done that..what else

 

[kizo]

You probably have an old version of MPR. No problem!
Connect with a short wire pin B42 and B30 for disable AC alarm detector.
