This posting is to clarify the status in which IPMCs will be delivered from now on and how they can be identified in-situ.
-
FRU:
We will write a string that identifies the batch into “Product Part Number” and the serial number of the IPMC into “Product Serial”. Note: The serial numbers restart at “0” for each new batch.
Example:
Command: ipmitool -I lan -H -U “” -P “” fru
Result:
Product Part Number : P2020002
Product Serial : 0000 0019 -
MAC address
The MAC address of the IPMC will be set by us to a unique value as part of the test procedure. To read it, use:
ipmitool -I lan -H -U “” -P “” lan print
Note: In ipmc-user/user_oem_examples.c · master · ep-ese-be-xtca / ipmc-project you can find OEM functions that allow you to read (and write) the MAC address. Modify the MAC at your own risk! -
EEPROM
In addition to the address range used for the FRU information, the EEPROM contains a section for user data. We are using 18 bytes in order to store a copy of the serial number and the batch identifier that you can also find in the FRU (see above). Please do not modify these fields.
