Managing the cooling system
5
Manually setting the fan speed
Typically, the management module, in conjunction with default settings of low and high
temperature thresholds, determines the speed of the two four-speed fans. (For information about
changing the low and high temperature thresholds, refer to
“Changing temperature thresholds for
modules and fan speeds”
on page 107.) You can manually set the fan speed using the
set-fan-speed command in the Global CONFIG level of the CLI.
For example, to set the speed of fan 0 to medium-high, enter the following command.
PowerConnect# set-fan-speed med-high
Syntax: set-fan-speed
<fan-speed>
For the
<fan-speed>
parameter, you can specify the following:
•
auto – The system is adjusted by the monitoring system.
•
high – The system sets the fan speed to high.
•
low – The system sets the fan speed to low.
•
med – The system sets the fan speed to medium.
•
med-high – The system sets the fan speed to medium-high.
Monitoring the cooling system
You can monitor the following aspects of the router cooling system:
•
The temperature of the fan control modules
•
The status and speed of the fans
•
The temperature warnings sent to the system log and that generate an SNMP trap
Displaying fan tray status and speed
To display the status and speed of the 4-speed fans in the router, enter the show chassis command
at any level of the CLI.
PowerConnect# show chassis
