Chapter 4. Managing the B24X
This chapter contains information about how to manage temperature settings and
how to remove MAC address entries.
Managing temperature settings
This section describes how to display temperature settings on the B24X and how to
change the temperature warning levels.
Using the temperature sensor
The B24X comes with two built-in temperature sensors; one at the air intake, and
the other at the exhaust (refer to Figure 27 on page 44). The temperature sensor at
the air intake monitors the incoming air temperature. The temperature sensor at the
air exhaust monitors the air temperature as it exits the device. The temperature
sensors cause the device to generate a Syslog message and SNMP trap if the
temperature exceeds a specified warning level The software reads the temperature
sensors according to the device poll time, which is 60 seconds by default. If the
temperature equals or exceeds the warning temperature the software generates a
Syslog message and SNMP trap.
You can use the CLI to perform the following:
v “Displaying the temperature”
v “Changing the temperature warning level” on page 28
v
“Changing the device temperature polling interval” on page 28
Displaying the temperature
By default, the software polls the temperature sensor every 60 seconds to get the
current temperature. This poll rate is controlled by the device poll time, which also
controls how often the software polls other system components.
To display the temperature of a device, enter the show chassis command at any
level of the CLI. The following shows an example output.
TurboIron#show chassis
Power supply 1 (NA - NA - Regular) present, status ok
Power supply 2 not present
Fan 1 ok, speed (auto): [[1]]<->2<->3
Fan 2 ok, speed (auto): [[1]]<->2<->3
Fan 3 ok, speed (auto): [[1]]<->2<->3
Fan controlled temperature: 0.0 deg-C
Fan speed switching temperature thresholds:
Speed 1: NM<----->30 deg-C
Speed 2: 25<----->40 deg-C
Speed 3: 35<----->90 deg-C (shutdown)

Displaying temperature messages
The software sends a Syslog message and an SNMP trap if the temperature
crosses the warning threshold. The following methods describe how to view the
