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

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 oc curs an d 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 w ith HA-standby or standby present,
only that supervisor module is shut down and the standby superv iso r modul e t akes ov er.
