Sleep Mode
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 documentation for information
about support for sleep mode. You can enable sleep mode in
software. Refer to the driver software documentation for more
information.
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
Specifications section for more
information about power consumption and thermal dissipation.
