2.2.8.5 Sensor Data Records
The AMC module has local Sensor Data Records (SDR) for storing the above men-
tioned information (temperature, voltage, and hot swap state). In addition to sensor
identification (type, name, unit, etc.), the SDR contains the configuration of the sen-
sor parameters that specify sensor behavior, such as threshold, hysteresis, event
generation capabilities, etc. Some of them can be configured through IPMI v1.5 com-
mands. The SDR can be queried with device SDR commands. The MMC sends the
AMC SDR event messages (e.g. AMC Module Hot Swap state) to the carrier man-
ager which then sends the data to the shelf manager and the user can access it
through the shelf manager or system manager.
Implemented module sensors are listed below.
2.2.8.6 Reset Types
Three types of logical resets are supported by the MMC.
!
Hard reset: the MMC resets all internal and external data/states to default val-
ues (such as internal message rings, sensor thresholds, hysteresis and event
enable masks, the states of the E-keying ports, and the state of the Blue LED
and FRU LEDs). When the AVR MMC is powered on, the MMC firmware detects
this condition and performs a hard reset of the AVR MMC. Another example is if
the management power drops below some critical value, a brown-out reset of
the AVR MMC occurs. When the management power returns to its normal
value, the AVR MMC is brought out of reset. The MMC firmware detects the
brown-out condition and performs a hard reset of the AVR MMC.
! Cold reset: the MMC resets all internal and external data/states to default val-
ues except for the overridden geographical address, overridden handle switch
state, the states of E-keying controls, and the states of the blue LED and the
FRU LEDs. One example for the cold reset scenario is if the watchdog timer of
the AVR MMC expires, a watchdog reset of the AVR MMC occurs. The MMC
firmware detects the watchdog reset condition and performs a cold reset of the
AVR MMC. Another example is if the front panel reset button is pressed for a
long period (>5s), the MMC will also execute a cold reset command. A cold
reset can be also executed by an IPMI command.
! Warm reset: it is similar to the cold reset with additional preserved external
data/states such as sensor threshold/hysteresis, sensor event masks, and sen-
sor events. On a warm reset, which can be also executed by an IPMI command,
the MMC firmware recovers its state from the data stored in the SRAM memory,
the contents of which is preserved across external and watchdog resets.
