FRU TLI Auto-Update
Oracle ILOM includes a top-level indicator (TLI) auto-update feature that ensures
that the TLI stored in the server field-replaceable units (FRUs) is always correct. The
TLI, which is unique to each server, is used to track the server service entitlement
and warranty coverage. When a server requires service, the server TLI is used to
verify that the warranty on the server has not expired.
The TLI is stored in the FRUID (field-replaceable unit identifiers) of these
components: power supply 0 (PSU 0), motherboard (MB), and disk backplane (DBP).
The TLI components stored in each component FRUID include:
■ Product name
■ PPN (product part number)
■ PSN (product serial number)
When a server FRU that contains the TLI is removed and a replacement module
installed, the TLI of the replacement module is programmed by Oracle ILOM to
contain the same TLI as the other two modules.
