Hardware Problem 2
Connecting to the remote modem fails.
Solutions:
1.
If using dialup, verify that your dialing information is correct. Make any
necessary changes to the ~, and redial if necessary.
2.
Check that the modems at your site and at the remote site are configured
in a compatible way. If not, reconfigure either set, as necessary, and redial.
3.
Check the cables:
•
Make sure all cables between the DEC MicroServer and the modem are
correctly connected.
•
Use loopback tests to check the modem control lines between the DEC
MicroServer and the modem. Chapter 2 describes loopback tests.
•
Replace any defective cable(s), and reload the system.
CAUTION
If you change an adapter cable, be careful not to accidentally press the
DUMP switch.
4.
Check the local modem:
•
Make sure the modem is turned on.
•
Make sure the communications line is correctly connected to the
modem.
•
Test the modem using its self-test facilities (if any). The manufacturer’s
information tells you what facilities are available and how to use them.
•
Use modem signal loopback tests to make sure the modem is working
properly.
•
Correct any faults, or replace the modem, and then reload the system,
if necessary.
5.
Use the remote loopback tests explained in Chapter 2 to check the
communications link and the remote modem. If the modem appears to
be faulty, have it repaired. If the link appears to be faulty, contact the
remote site to request further fault diagnosis.
