3.7.6 CPU Monitor Screen
Fig. 3.7.6.1 The CPU Monitor Screen
The Maintenance: CPU Monitor screen, shown in Figure 3.7.6.1 on page 72, is used to monitor
fan speed and temperature for the CPU. Current temperature and fan speed values are displayed
on the left, while text fields in the Alarm & Warning Data box on the right are used to control
when alarms and warnings are shown. These text fields may be edited by any user with Manager
or higher access. Changes will stay in effect until the next time the power is cycled.
A warning is generated whenever the CPU temperature reaches the Warning CPU Temp. When
the CPU temperature reaches Alarm CPU Temp an alarm will occur. The Hysteresis CPU
Temp is used to control when an alarm will disappear after the temperature starts to decrease.
Once the temperature starts to drop, the alarm will exist until the CPU temperature reaches
(Alarm CPU Temp – Hysterisis CPU Temp). The system generates a warning when the fan
RPM falls under the Warning Fan Speed, and an alarm occurs when the fan speed drops below
Alarm Fan Speed.
