• Serial Over LAN (SOL): The A2F500 connects to the BCM5221, which is
connected to the base switch. The LMP serial console connects to either the
front panel RJ-45 console port or to the SOL port (UART #0), but not at the
same time.
• Payload Interface: By UART #1 port, the IPMC communicates with the LMP.
• RTM Management: The IPMC communicates with the RTM MMC through the
hot-swap buffer and IPMB-L for FRU information and Command exchange.
• IPMB-A/B Interface: The IPMC communicates with the Shelf Manager via the
redundant IPMB-A and IPMB-B interfaces on ZONE 1 connector through the
hot-swap buffer.
• Blade Power Sequence: All the power rail enable/disables are controlled by the
IPMC GPIO.
• Power Monitoring: All the power rails are monitored by the IPMC and any
violation on the level is reported to the Shelf Manager. When a violation is
observed, the IPMC shutdowns the FRU.
• FRU Information: The EEPROM that contains the FRU information, Log, alarm
information, etc is connected to the IPMC via the master only I2C.
• Sensor: Various sensors including thermal and power are connected to the
IPMC via the master only I2C. The IPMC monitors sensor information.
