Symptoms

This issue could possibly be seen on any T3-x or T4-x servers / blades.

 Upon initial power on, T4-4 shows the below errors in Host-Config:

[CPU 1:0:0] ERROR:   N1.MCU0.BoB0.Ch0.D0.R0.St 0, No Eye Found and there is no rank sharing.

 However later when POST completes, it does not show any errors:

 When the banner appears, only half of the memory is displayed and it does not proceed with the normal auto-boot sequence.
