The Peripheral Manager provides additional feature and is equipped with following peripherals:
•
The firmware Flash device contains up to two firmware images
•
The FRU Data Flash device contains the CP6930-1 FRU information
•
Internal watchdog monitoring PM operation
•
The external watchdog is implemented in glue logic. The PM will be reset if its alive signal fails. The watchdog is dis-
abled in case of a local update.
3.3.1
IPMB Interface
The CP6930-1 IPMI firmware implements the two independent IPMB-0 and IPMB-1 interfaces.
The IPMB-0 can be switched to a redundant mode by aggregating the physical IPMB-0 and IPMB-1 lines together to one sin-
gle logical IPMB-0. In redundant mode, command retries are send over the second physical line if the command timed out
using the first line.
3.3.2
Voltage and Current Sensors
The following voltages and currents are measured by the Peripheral Manager:
The complete list of sensors and their alarm thresholds can be found in chapter “Board Sensors” on page 54.
