Note
Because of the similarity of some communication options, MDM sees
them as the same device. A CXA16 and CXB16 appear the same to
MDM. A generic device name, DH–CX0, is listed for such options,
and the last letter in each name shows the difference. For example,
DH–CX0A indicates one option, DH–CX0B a second, and so forth.
If a device fails the test, you receive a failure message which identifies:
• The device tested
• When the failure occurred
• The field-replaceable unit (FRU)
Copy the failure message and report it to your Digital service representative.
This shows an example of an unsuccessful test.

If your system has serious problems, the following message appears.
All devices disabled, no tests run.
Report that message to your Digital service representative.
After a failure message appears, the testing stops.
After all devices pass the first part of the test, the exerciser tests begin. Those
tests take about 4 minutes and test how the devices work together. If the
devices pass, you receive a success message.
At the end of the tests, press
Return
to return to the Main Menu.
From the Main Menu you can exit MDM as described in Section 2.6 or you can
select one of the other options.
