Bmc Led Control; Field Replaceable Unit Information; System Event Log Information; Smbus Address Map - Intel NetStructure ZT 5504 Manual

Control Functions
• CPU board Reset Control
• CPU board power on/power off control
• CPU NMI Assertion to processor
• Dual Domain Mode (TBD)

BMC LED Control

The BMC controls the following status LED pins:
LED0 FP_BMC_BLUE_LED-
LED1 RP_BLUE_LED-
LED2 Health LED (normal - green)
LED3 Health LED (needs attention - amber)
LED4 Not used
LED5 Not used

Field Replaceable Unit Information

The BMC controller monitors Field Replaceable Unit (FRU) information for the ZT 5504 and a
rear panel I/O board (if present). Each device has its own address.

System Event Log Information

The BMC controller stores system event information in an 8K x 8 serial EEPROM device. Both
the in-band KCS interface and the out-of-band IPMB interface provide access to the System
Event Log (SEL). This allows SEL information to be accessed through the IPMB interface even
if the system is down.
