4-1 Operational Check and Trouble Shooting
Chapter 4. Operational Check and Trouble Shooting
This chapter indicates how to check that your modem is operational. It provides also a few
answers to commonly asked questions.
Operational Check
If the modem is used with RSF, to check that your modem is operational, you must contact
the Service Organization
responsible for installing and configuring RSF at the customer’s
site.
Operational check should be performed by the Service Organization as follows:
•
Installing, Setting up, Starting RSF,
•
Using RSF ’Test & Reset Modem’ menu
This is described in
RSF (Remote Service Facilities) Field Guide,
Section ’Test & Reset
Modem’.
Trouble Shooting
If the operational check fails, you, or a person from the Customer Service Center, should:
•
Check the cable is properly connected between the modem and your telephone wall jack
as described on page 2-3.
•
Check the existence of the ’modem tty line’
# lsdev –C –ctty –S a | grep ‘lsdev –C –ts4a –S a –r
location‘
Run
smit tty
Select the ’Change/Show Characteristics of a TTY’ menu function
If it does not exist, check that the ISA Internal Modem LPP has been installed on your
system as described on page 3-1, then check the modem configuration as described on
page 3-3.
•
Check the jumper setting, as described on page 2-2.
If the checks cited above are successful and the modem is still not operational, you may:
•
See in the system errlog report if an error concerning the modem has been reported.
•
Use the AIX system trace mechanism to trace your tty line. The Hook-Id to be used with
the
trace
command (or the SMIT Problem Determination/Trace submenu) is
HKWD_STTY_RS (0x406). Refer to
AIX Version 4.3 Problem Solving Guide and
Reference
for more information.
•
Run Diagnostics Tools by typing
smit diag
then selecting the following:
Current Shell Diagnostics
Diagnostic Routines
System Verification
Choose the ’Serial port on Bull ISA internal modem’ in the Diagnostic Selection menu.
The modem adapter is OK if the COMMAND STATUS report is OK. Otherwise, diagnostic
information is displayed indicating the appropriate action to be taken.
