does make usage of the interrupt number provided there. Making changes ‘manually’ leaves
SMBIOS IPMI entry with not-up-to-date values until next reboot.

6.6 Firmware / Module Identification

There are two ways to determine via IPMI that a MMC resides on an AM4010.

1. The response on the IPMI command “Get Device ID” offers among others the the

following response data:
• Manufacturer ID = 3A98h (Kontron IANA ID)

• Device ID = 04h (H8S2166)
• Product ID = 4010

• Firmware Revision - depends on running firmware.

2. The Device ID String which can be found by reading the the Management Controller

Device Locator Record (SDR Type 12h) contains the string “AM4010”. For a module
being placed in bay B3 the Device ID String will be “B3: AM4010”.

6.7 FRU

Information

6.7.1 Structure and functionality

The MMC provides 4 kB non-volatile storage space for FRU information. Some of the data
stored there, like Module Current Requirements record or E-Keying information (refer to
AMC.0 specification for details), are mandatory for module functionality in the ATCA/AMC
environment. Refer to [2] Platform Management FRU Information Storage Definition
document for details).

Please note that missing FRU information will prevent the AMC module from being accepted
by the carrier controller during the Hot Swap process and the module will get no payload
power.

Full low level access to read or write a module’s FRU Information is provided by regular
IPMI FRU Device commands. Please be careful when writing FRU information directly using
standard IPMI commands. Damaging the FRU Information may lead to a non working
payload.

To avoid this danger there exists a Kontron Linux tool ‘frum’ (refer to section 12.2), which
allows to display and partially modify FRU data. E.g. the ‘frum’ tool makes it easy to modify
Product Info Area fields (like Product Version or Product Serial Number).

6.7.2 Download

Normally the user needs not download the FRU information because the module is shipped
with the data which describes best the module capabilities and requirements. Remember that
FRU information might be damaged by a write access to the IPMI FRU Device using
standard IPMI commands.
