Managing modules
This section describes the commands that allow you to manage the modules
installed in the Cajun M770 ATM Switch.
Viewing the Clock Source Ports
You can display the source of the ATM module’s clock by the
hardware clock
show
command. Only M770 ATM switches that have an M-SPS installed have the
ability to synchronize its clock. If the M770 Supervisory Module is the M-SPX, the
module will always use its local clock.
