Introduction

The intent of this document is to address the issue seen regarding Trusted Platform Module (TPM)
related System Event Logs (SEL) events on some C460 M4 servers. A small number of C460 M4
SPARE servers will see a critical SEL event related to TPM presence right out of the factory. The
instructions below will assist you in resolving servers impacted by this issue.

Problem

Potentially Impacted Systems:

About 614 SPARE C460 M4 Systems (Shipped between June 2

nd 

2014, and April 13

th

 2016.)

Customer Visibility / Impact:

Customers may see a critical SEL event similar to the one below on servers received from the
factory.

There is NO operational impact to the server, but the message may lead to unessary concern
resulting in a call to TAC. This has to do with the way TPMs were handeled in manufacturing.
C460 M4 systems keep a "Cached" value for TPM presence, indicating if a TPM was was ever
installed in the server - every server has a TPM installed durring testing. The C460 M4 also tracks
the current precense of the TPM, and since all servers ordered as spares ship without a TPM, the
system triggers an alarm thinking that the module that was once installed has been removed.

Solution

The work-arround below will allow you to quickly address this SEL event should you wish to
remove the messages. The work-arround involves resetting the Integrated Management Controller
