Sensors
Several on-board sensors collect status data and relay the information to the Intelligent
Platform Management Controller.
Table 2-12, “CPC324 Sensors,”
describes each on-board
sensor.
Interpreting Sensor Events
Performance Technologies adopts the following philosophy with respect to threshold sensor
event severity levels:
•
Non-critical — A warning that things are somewhat out of normal range, but not really a “problem”
yet. See
“Non-Critical Events”
below.
•
Critical — Things are still in valid operating range, but are getting close to the edge; unit still operating
within specified tolerances. See
“Critical Events”
below.
•
Non-recoverable — The unit is no longer operating within specified tolerances. See
“Non-
Recoverable Events”
below.
Non-Critical Events
Non-critical events are informative only - they do not indicate that the blade is outside of its
operating limits. In general, no action is required. However, in certain contexts, system/shelf
management software may decide that preventive action should be taken. For example, if
several blades in a shelf report upper non-critical temperature events, the shelf manager might
decide to increase fan speed.
Critical Events
Critical events indicate that the blade is still within its operating limits, but it is close to
exceeding one of those limits. Possible action in this case is to closely monitor the alarming
sensor and take more aggressive action if it approaches the non-recoverable threshold.
