Information About Module Temperature
Shutting Down a Supervisor or I/O Module
To perform a graceful shutdown of a supervisor or I/O module, use the out-of-service module command 
to specify the slot with that module as follows:
switch# out-of-service module 
slot
Shutting Down a Fabric Module
To perform a graceful shutdown of a fabric module, use the out-of-service xbar command to specify the 
fabric slot with that module as follows:
switch# out-of-service xbar 
slot
Information About Module Temperature

Overview of Module Temperatures
Built-in, automatic sensors are provided in all switches in the Cisco Nexus 7000 Series to monitor your 
device at all times. 
Each module (supervisor, I/O, and fabric) has temperature sensors with two thresholds: 
  • Minor temperature threshold—When a minor threshold is exceeded, a minor alarm occurs and the 
following actions occur for all four sensors: 
  –
System messages are displayed. 
  –
Call Home alerts are sent (if configured). 
  –
SNMP notifications are sent (if configured). 
  • Major temperature threshold—When a major threshold is exceeded, a major alarm occurs and the 
following actions occur: 
  –
For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur: 
System messages are displayed. 
Call Home alerts are sent (if configured). 
SNMP notifications are sent (if configured). 
  –
For sensor 2 (intake sensor), the following actions occur: 
If the threshold is exceeded in a switching module, only that module is shut down. 
If the threshold is exceeded in an active supervisor module with HA-standby or standby present, 
only that supervisor module is shut down and the standby supervisor module takes over.
