Managing Module Hardware

This chapter describes how to use the command-line interface to manage modules
installed in a Cajun M770 ATM Switch. For information about how to access and
use the Cajun M770 ATM Switch command-line interface, see Chapter 3 How to
Use the Command-line Interface.

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.
Command:
Output: from a module whose port is NOT being used to synchronize the
Output: from a module whose port IS being used to synchronize the ATM
Output: from a module which cannot be used to synchronize the ATM
