Displaying temperature warnings
If the temperature of a module exceeds the high temperature threshold for any of the fan speeds,
the system sends a message to the system log. This section describes how to view the system log.
If you have configured the system to use a Syslog server, refer to the documentation for the server
or receiver.
To display the system log, enter the following command at any CLI level.
Syntax: show log

TABLE 25 Fan status and speed fields
This Field... Displays...
Status The status of the fan. This field 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 at which the fan is currently operating (denoted by double brackets).
This field shows one of the following:
• 1 (low) – The fan is functioning at 25 percent of capacity.
• 2 (medium-low) – The fan is functioning at 37 percent of capacity.
• 3 (medium) – The fan is functioning at 50 percent of capacity.
• 4 (high) – The fan is functioning at 100 percent of capacity.
NOTE: If the report shows that a fan has “failed”, the report does not show the fan’s speed.
