Have you replaced the pwr supply and/or cp card? I've never run across a diagram in the ntp's.

 

[Jeffnortel]

if the CP card is the only card not powering up, I would start with replacing it.

This CE pwr supply was in core 0 , i swaped the same with the supply of core one , with the shifting of power supply the fault is also shifted , now CP core one became un-powered. its means that isuue is in CE power supply.
Please suggest me what to do next, or any one can me the circuit diagrams for the same, i shall be thank ful to all of u , for supporting.

Regards to all

Exactly this is what i am saying , that CE Per Supply module is faulty , Now can any one provid me the Circiut Diagrame of CE Power Supply having part Number NT6D41CA ,

Not sure exactly what your after but the CE Power Supply slides into the Chassis backplane with 4 main pin Inputs and an Earth connection along with 64 circuit pins for connection

Try the 'TUV Rheinland' WEB Site

Cheers!!

The power supply is bad. I see this all the time. If the light on the power supply is not bright then it is bad. There is no circuit diagram since the part is patented and propietary. I have been at Nortel in Meridian/CS1000 support for 10+ years and have never seen (or needed) a circuit diagram of any hardware. Replace the power supply.
