3.21 How to Control Temperature/Fan Speed
Temperatures are reported to the user in degrees Celsius (° C) and degrees
Fahrenheit (° F).
Host Card Monitoring
The die temperature of the main components on the Host card are monitored, and
reported to an accuracy of ±2 °C.
A host card temperature alarm threshold can be set that, if exceeded, causes a
System Over Temperature Alarm to be generated.
Note: It is recommended that the default threshold settings are not adjusted.
Option Card Monitoring
Option cards monitor the die temperature of their main components, and report
these temperatures to an accuracy of ±2 °C. If an option card reports die
temperatures, it allows an alarm threshold to be defined for each temperature, which
if exceeded causes an alarm to be generated.
Note: It is recommended that the default threshold settings are not adjusted.
VCMs
The controlling processor monitors the core temperatures of the main components
and passes this information back to the host card via the back plane for monitoring.
Temperature thresholds can be set to cause a warning or an alarm. The warning
level is configurable by the user, whereas the alarm level is hard coded.
Note: It is recommended that the default threshold settings are not adjusted.
Fans
The fans fitted to the chassis are speed controllable, providing a limited range of
operating conditions.
To control temperature/fan speed:
1. Go to the Device Control > Advanced Setup > Base Unit page.
2. Using the slide bar control, set to Lowest Noise , Quiet , Cool or Best Cooling ,
as required.
