Managing the cooling system
DRAFT: BROCADE CONFIDENTIAL
Brocade# 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.
Brocade# show chassis
...
--- FANS ---
Back fan tray 1: Status = OK, Speed = LOW (50%)
Back fan tray 2: Status = OK, Speed = LOW (50%)
Back fan tray 3: Status = OK, Speed = LOW (50%)
Back fan tray 4: Status = OK, Speed = LOW (50%)
Syntax:
show chassis
For information about all output generated by the
show chassis
command, refer to
“Displaying device status and temperature readings”
on page 214.
Displaying temperature warnings
If the temperature of a module exceeds the high temperature threshold for any of the fan speeds, the system sends a warning message to
the system log and an SNMP trap. (For more information about the low and high temperature thresholds, refer to
“Changing temperature
thresholds for modules and fan speeds”
on page 222.) This section describes how to view the system log. If you have configured your
router to use a Syslog server or SNMP trap receiver, refer to the documentation for the server or receiver.

Fan status and speed fields
Field
Description
Status
The status can be one of the following:
•
OK – The fan is functioning properly and is keeping the temperature of each module within an
acceptable temperature range.
•
Failed – The fan is not functioning properly or the fan control module cannot control the fan.
Speed
The speed can be one of the following:
•
LOW – The fan is functioning at 50 percent of capacity.
•
MEDIUM – The fan is functioning at 75 percent of capacity.
•
MEDIUM-HIGH – The fan is functioning at 90 percent of capacity.
•
