Temperature Monitoring
The ADM1026 also monitors the CPU diode temperature on the Netra CP3260 blade
server. The ADM1206 and H8 firmware reports a minor, major, or critical alarm
when the temperature of the CPU goes beyond the thresholds listed in
TABLE 5-2
.
Also, if the temperature of the CPU goes beyond the
Emergency H8 Shutdown
value listed in
TABLE 5-2
, the H8 initiates a event/warning blade server to the shelf
manager and shuts down.
