Changing the Chassis Polling Interval
The procedure for changing the chassis polling interval on the FESX and FWSX is the same as that on the FES
device. See “Changing the Chassis Temperature Polling Interval” on page 5-3.
Adjusting Temperature Thresholds
The FESX and FWSX devices provide default settings for temperature thresholds associated with fan speed
switches. Therefore, no initial configuration is necessary. If desired, you can change the settings.
By default, the system uses the temperature thresholds shown in Table 5.2.
Changing the Temperature Threshold for a Fan Speed Switch
To change the temperature threshold for a fan speed switch, enter a command such as the following:
FESX Switch# temp fan-speed slow-to-medium 30
This command causes the system to switch the fan speed from slow to medium if the system’s temperature
reading exceeds 30
°
C.
Syntax:
temp fan-speed <speed-switch> <threshold-value>
where:
<speed-switch> can be one of the following:
•
fast-to-medium
•
medium-to-fast
•
medium-to-slow
•
slow-to-medium
<threshold-value> is a temperature in Centigrade. Table 5.2 shows the default and recommended temperature
thresholds. When changing the temperature threshold for a fan speed switch, remember that the temperature
threshold of a higher fan switching speed must be higher than the temperature threshold of a lower fan switching
speed.
