C3945 Router Rommon Boot problem

[cjd161280]

Cisco router 3945 when unpacked from the box and powered on , it was not able to find boot loader image and booted in ROMMON mode. tried to boot from the external flash and tftp but still not able to.

Does anyone faced the similar problem and know whats the solution for the same.

Can be mislodged ot bad memory module. Or, can be the the NPE module faulty.

I'm going to agree with Paolo.  You may need to return the 3900 router to Cisco (class as Dead On Arrival).  Either the memory has jarred loose or the memory is faulty.
