Temperature and Voltage Sensors

Temperature and voltage readings are monitored by ADM1026. They are critical sensors that
ensure the MPCBL0001 is operating at its predefined threshold limits. The sensors are categorized
as follows:

Lower Non-Critical

Lower Critical

Upper Non-Critical

Upper Critical

If the lower critical or upper critical threshold is exceeded, it raises a major alarm. If the lower non-
critical or upper non-critical threshold is exceeded, it raises a minor alarm.

Only critical thresholds which are exceeded turn the Health LED solid red. However, for any
events above, IPMC forwards the events to the shelf manager to log it into shelf manager’s SEL.
