2.3 Shelf Address
The shelf address / carrier number is usually set via a DIP switch on the backplane. The ad-
dress is read one time at start-up by the MCH. For this reason, the MCH must be reset or cold
started after any changing of the address. Invoking the CLI command “showshaddr” will return
the shelf address / carrier number. Refer to Environmental Options for further assistance.
2.4 FRU IDs
In accordance with the MicroTCA specification, the following FRU IDs are valid for the MCH.
They are used as a parameter in many IPMI commands. The table below reflects the FRU IDs
from the standpoint of the MCH.
Example 1:
The FRU data of the AMC module in slot 3 is selected via the FRU-ID 7 when the MCH receives
an IPMI command containing the FRU-ID as a parameter (e.g. “ipmitool ... fru print 7”). When
the IPMI command is addressed directly to the AMC module, then using FRU-ID 0 will provide
the same result (e.g. “ipmitool ... fru print 0”). This is true regardless of the slot position of the
AMC module.
Example 2:
When activating the system or individual AMC modules via the IPMI commands “Set FRU
Activation” or “Set FRU Activation Policy”, the FRU-IDs in the table below apply. The IPMI
commands must be addressed directly to the MCH.
