X2-8 (X4800 M2) Fails to boot after FW upgrade

HI,

We have a X2-8 (X4800 M2) server which fails to boot as soon as its powered on.

Apparently there was a NEM failure post Firmware upgrade to Version 3.2.10.21.a r120301. Latter part was replaced and firmware was upgraded to latest 4.0.2.25 r122615. However, the server still shows no sign to boot.
