Displaying Module Temperature - Cisco DS-C9216I-K9 Configuration Manual

Chapter 10 Managing System Hardware

Displaying Module Temperature

Each module (switching and supervisor) has four sensors: 1 (outlet sensor), 2 (intake sensor), 3 (onboard
sensor), and 4 (onboard sensor). Each sensor has two thresholds (in Celsius), minor and major.
A threshold value of -127 indicates that no thresholds are configured or applicable.
Note
When a minor threshold is exceeded, a minor alarm occurs and the following action is taken for all four
sensors:
•
•
•
When a major threshold is exceeded, a major alarm occurs and the following action is taken as follows:
•
•
Switch shut down only happens after a two-minute interval. During this interval the software monitors
Note
the temperature every five (5) seconds and continuously sends syslog messages as configured. If the
required action is not taken (for example, a new fan module is inserted to decrease temperature) and if
the temperature does not come down, the system is shut down at the end of two minutes.
To monitor sensor temperature attributes, perform the following steps.
From the Fabric Manager menu tree, choose Switches > Modules and then click the Temperature
Step 1
Sensors tab, or from Device Manager, choose Physical > Temperature Sensors.
The Information pane from the Fabric Manager displays sensor temperature attributes for multiple
switches. The Sensors dialog box from the Device Manager displays sensor temperature attributes for a
single switch.
Configure the sensor attributes.

Syslog messages are displayed.
Call Home alerts are sent (if configured).
SNMP notifications are sent (if configured).
For sensors 1, 3, and 4 (outlet and onboard sensors):
Syslog messages are displayed.
–
Call Home alerts are sent (if configured).
–
SNMP notifications are sent (if configured).
–
For sensor 2 (intake sensor):
If the threshold is exceeded in a switching module, the module is shut down.
–
– If the threshold is exceeded in a supervisor module with HA-standby or standby present, the
supervisor module is shut down.
– If the standby supervisor is not present, the entire switch is shut down.
