Hardware Problem 4
The Gateway-ST boots, but you cannot establish a connection with the IBM
computer.
Solutions:
1.
Make sure the modems are compatible.
2.
Make sure the values for the STATION ADDRESS and STATION ID
parameters correspond to their IBM counterparts in DECnet SNA Gateway-
ST Guide to IBM Parameters. If the parameters are wrong, change them
by using SNANCP commands. (For information about using SNANCP,
refer to DECnet SNA Gateway-CT and ST management.
Use SNANCP SHOW commands to check the values specified for STATION
ADDRESS and STATION ID:
SNANCP> SHOW CIRCUIT
circuit-id CHARACTERISTICS
and for SSCP ID:
SNANCP> SHOW PU
pu-id CHARACTERISTICS
If the SSCP ID is not shown, you have not defined it. Section 1.2,
Initialization Problem 6 contains more information about these parameters.
To ensure that the correct values are supplied the next time the Gateway-
ST is down-line loaded, edit the SNA configuration file on the load host:
SYS$COMMON:[SNA$CSV]SNAGATEWAY_gateway-node-name_SNA.COM
After you have edited the configuration file, reload the Gateway-ST.
3.
Check your modems. If a modem is defective, replace it. Work through the
following procedures to test your modems:
•
Check that the pairs of modems on a particular line are compatible and
that you have similar strapping options on each modem.
•
Refer to the documentation that accompanies each modem, and do the
following:
Make sure the modem is turned on.
Make sure the modem is installed correctly.
Run an internal modem test.
•
If you experience a problem on a dial-up line (for example, you get the
carrier-detect signal but still cannot pass data through the modem),
make sure you have similar modems in the link.
