CPU mismatch
error
E5
System halted because a fatal error related to the CPU
family/model/cache/UPI speed mismatch was detected.
The integrated BMC may generate LED codes based on detection of failure conditions. These LED codes are
translated into visual LED sequences each time the problem is discovered, such as on each power-up
attempt, but are not lit continuously.
Codes that are common across Intel server boards and systems that use same generation chipset are listed
in the following table. Each digit in the code is represented by corresponding number of LED flashes.

Reason for LED Blink Associated Sensors
1-5-1-2 VR watchdog timer sensor assertion.
VR watchdog timer
1-5-1-4
A PSU reports a failure, or the BMC detects the presence of a PSU
model that is incompatible with one or more other PSUs in the system.
PS status
1-5-2-1 No CPUs installed or the first CPU socket is empty.
