This module supports a low-power sleep mode. Support for sleep 
mode at the system level depends on the chassis that the module is 
plugged into. Refer to the chassis manual for information about 
support for sleep mode. If the chassis supports sleep mode, refer to 
the software help for information about enabling sleep mode. Visit

C Series documentation.

Typically, when a system is in sleep mode, you cannot 
communicate with the modules. In sleep mode, the system 
consumes minimal power and may dissipate less heat than it does 
in normal mode. Refer to the 

 section for more 

information about power consumption and thermal dissipation.
