13.6.2Two-Wire Serial Interface Based

FRUs such as sensors, EEPROMs, or similar devices that have support for the two-wire serial bus (I2C) can be hooked on shared or dedicated I2C buses. Examples are the Atmel* AT24C64/16 EEPROMs and the DS75 temperature sensor.

13.7Non-Intelligent FRUs without I2C Support

The GPIO pins and (if needed) the dedicated I/O pins of the CMM can be used to allow FRUs that do not support the I2C bus to communicate with the CMM. For example, the air filter tray used on the Intel NetStructure MPCHC0001 chassis communicates with the CMM in this manner. In that chassis some of the seven GPIOs shown in Figure 33 are used to control the LED and to detect the presence of the filter tray. Also, readings from two temperature sensors (thermistors) on the filter tray are wired to the ADM1026 on the CMM board.

13.8FRU Data Storage for Non-Intelligent Devices

Version 6.1 of the CMM firmware for the MPCMM0002 currently supports the Atmel Corporation* AT24C64 or AT24C16 EEPROMs and the Microchip Technology* 24LC256 EEPROM for the storage of FRU data on any non-intelligent device in the chassis. In particular, the chassis FRU data must be stored on one of these EEPROMs, each of which can store up to 8 kilobytes of data.
