med-high – The system sets the fan speed to medium-high.
Monitoring the cooling system
You can monitor the following aspects of the BigIron RX Series 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
The CLI provides two commands that allow you to display the status and speed of the four-speed
fans in the BigIron RX Series chassis. To display this information, you can enter the following
command at any level of the CLI:
Syntax: show chassis
For information about all output generated by the show chassis command,refer to “Displaying
chassis status and temperature readings” on page 113.
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 117.) This section describes how to view the system log. If you
have configured the BigIron RX Series system to use a Syslog server or SNMP trap receiver, refer to
the documentation for the server or receiver.
