50 Second-Generation Channel Interface Processor (CIP2) Installation and Configuration
Running CIP2 Diagnostic Tests
The interface has to pass the first five tests. The sixth test (which is the same as the fifth, but with a
different mode for the optical wrap plug for the ECA, instead of electrically wrapping the interface)
will fail if no wrap plug is installed or if the interface is connected to the channel. This type of failure
will not affect the channel.
If a wrap plug is inserted, following is how the wrap diagnostics will be repeated:
• Until a failure occurs
• Until the wrap plug is removed (which may be reported as a failure depending on when you pull
the wrap plug)
• Until you enable the second adapter (as in a dual channel CIP2)
If you suspect that an adapter might be the cause of a problem you are seeing, you can run a single
pass of the diagnostic tests on an installed PCA or ECA interface by entering configuration mode
and specifying that the console terminal will be the source of the configuration subcommands, as
follows:
Router# configure terminal
Next, specify the slot/port number (interface processor slot number/port number) of the interface for
which you want the diagnostic tests to run by entering the interface channel command followed by
the slot/port of the interface.
The example that follows is for a CIP2 interface in interface processor slot 1:
Router(config)# interface channel 1/0
To run the diagnostic tests once, enter the shutdown command and then the no shutdown command,
as follows:
Router(config)# shutdown
Router(config)# no shutdown
Ctrl-Z
Router#
The no shutdown command causes the diagnostic tests to run on the PCA or ECA interface you
selected. If no failures occur, you can rule out that adapter as the source of your problem.
