Internal Health Red Light Issue - ML350 G5 Proliant Servers

[networkn]

Hi There!

We are starting to see a number of our deployed ML350G5 Servers falling over with a red flashing light for internal health. Internally the red light is most often beside the PPM2 which is strange since there is no second processor installed (Nor was there ever). 

Has anyone else seen this and know what component we should be looking to replace? 

Sometimes if we are lucky unplugging the power on the server helps. Most of the it's game over for that server.
