Lower non-critical
going low
The temperature has dropped below its lower
non-critical threshold.
1. Check for clear and unobstructed airflow into
and out of the chassis.
2. Ensure the SDR is programmed and correct
chassis has been selected.
3. Ensure there are no fan failures.
4. Ensure the air used to cool the system is within
the thermal specifications for the system
(typically below 35°C).
The temperature has dropped below its lower
critical threshold.
Upper non-critical
going high
The temperature has gone over its upper non-
critical threshold.
Upper critical
going high
The temperature has gone over its upper
critical threshold.
12.2 Hard Disk Drive Monitoring Sensor
The new backplane design for EPSD Platforms Based on Intel

Xeon

Processor E5 4600/2600/2400/1600 Product Families moves
IPMI ownership of the HDD sensors to the BMC. Note that systems may have multiple storage backplanes. Hard Disk Drive status
monitoring is supported through disk status sensors owned by the BMC.

60h-68h = Hard Disk Drive 15-23 Status
F0h-FEh = Hard Disk Drive 0-14 Status
Event Direction and
Event Type
[7] Event direction
0b = Assertion Event
1b = Deassertion Event
[6:0] Event Type = 6Fh (Sensor Specific)
[7:6] – 00b = Unspecified Event Data 2
[5:4] – 00b = Unspecified Event Data 3
[3:0] – Event Trigger Offset as described in Table 90
