NO. Requirements in this Relationship with related specifications from other SDOs
Recommendation
32 Providing running – [b-OCP 1S] provides temperature and power sensors set as 'Each card must
information provide following sensors: Temperature sensors for SOC, DIMM, voltage
regulators and other critical chips' in clause 6.5.
– [b-OCP 2S] provides running monitor set as 'The vendor should implement
BMC FW to support thermal monitoring, including processor, memory,
chipset, VRs, PCIe card, Mezzanine cards, Inlet/outlet air temperature and
airflow sensor' in clause 9.8.
– [b-OCP AMBH] provides memory reliability as 'Hardware health monitoring
display' in clause 5.5.
– [b-OCP JBOG ] provides monitor set as 'The BMC implemented is to have
access to all analog sensors placed in the system and ensure that they are
displayed in a sensor data record repository' in clause 7.9.1.1.
– [b-OCP Yose] provides monitor set as 'During the entire hot-service process,
the BMC shall monitor the thermal condition closely' in clause 5.2.
– [b-OCP AMBH] provides monitor set as 'The BMC can be used to monitor
hardware and control fan speed' in clause 6.
– [b-OCP OBIOS] provides multi process configuration set as 'BIOS
requirements for Intel NM enabled firmware NM5 BIOS should implement
processor utilization notifications support in ACPI tables' in clause 9.2.2.

33 Automatically power – [b-OCP 1S] provides power operation set as 'The Twin Lakes 1S server can
operation throttle itself down to lowest possible power state as quickly as possible
when the platform asserts the FAST_THROTTLE_N signal or it receives
request from BMC, or over power event reported by on-card power
monitor' in clause 8.4，and 'The BMC controls power on, off and reset
directly via the signals defined in the pin-out' in clause 9.7.13.
– [b-OCP 2S] provides auto power on set as 'Motherboard should be set to
restore last power state during AC on/off. This means that, when AC does
on/off cycle, motherboard should power on automatically without requiring
power button' in clause 15.9.
– [b-OCP JBOG] provides power operation set as 'Support power on policy to
be last-state, always-on and always-off upon recovery from an AC power
loss event. T' in clause 7.7.
– [b-OCP Yose] provides auto power set as 'Now the user can replace the
failed unit with a new one, BMC would automatically resume power and
boot the new card' in clause 5.2.
– [b-OCP OBIOS] provides power controller set as 'The following actions are
available on expiration of the Watchdog Timer: • System Reset• System
Power Off• System Power Cycle• Pre-timeout Interrupt (OPTIONAL)' in
clause 9.2.2.
34 Monitoring
environment condition
35 Self-checking – [b-OCP 2S] provides get selftest result set as 'Get Selftest Results (0x04) in
mechanism clause 9.13.
– [b-OCP TP] provides selftest set as 'During system boot-up, POST (Power-
On-SelfTest ) codes will be send to port 80 and decoded by the BMC to drive
the LED display as described in section 8.5. P' in clause 8.2.
– [b-OCP OBIOS] provides selftest set as 'Built-In Self-Test (BIST) The
BIST_ENABLE can be controlled by a BMC, GPO, strap or other mechanism.
BIOS shall implement a platform policy to control BIST execution' in
clause 4.12.
