Management Resources
The RTM-ATCA-F140 does not include its own management controller (MMC) and cannot
independently support the ATCA hot-swap protocol. However, it does support hot-plugging.
The RTM-ATCA-F140 provides the necessary resources to allow management by the front-
blade IPMC. These resources are associated with a dedicated I2C port connected to the front-
blade IPMC.
4.2.1
FRU Serial EEPROM
The RTM-ATCA-F140 provides a 128Kb (16K byte) I2C serial EEPROM. This is a 24LC128T-type
device. The EEPROM resides at I2C address 0xA0. It is supplied with +3.3V management power
and thus is available regardless of payload power.
This serial EEPROM is intended to hold FRU data and any additional parameters that are
required.
4.2.2
Temperature Sensors
The RTM-ATCA-F140 has provision for three temperature sensors that are located on the
primary side of the board close to the top, middle and bottom of the RTM. These sensors are
I2C-based LM75-type devices.
The over-temperature outputs from the three sensors are connected to the RTM FPGA to allow
an interrupt to the service processor to be generated in the event of an over-temperature
condition.
The I2C addresses for these devices are 0x90 (upper), 0x92 (middle) and 0x94 (lower).
