Table 4-3 RMC Troubleshooting Tips
Symptom Possible Cause Suggested Solution
You cannot enter the
RMC from the modem. The RMC may be in soft bypass
or firm bypass mode. Issue the show com1_mode command
from SRM and change the setting if
necessary. If in soft bypass mode, you
can disconnect the modem session and
reconnect it.
The local terminal
cannot communicate
with the RMC correctly. System and terminal baud rates
do not match. Set the baud rates for the system and
terminal to be the same. For first-time
setup, suspect the console terminal, since
the RMC and system default baud is
9600.
RMC will not answer
when the modem is
called. Modem cables may be
incorrectly installed. Check modem phone lines and
connections.
RMC remote access is disabled
or the modem was power cycled
since last being initialized. From the local serial terminal or VGA
monitor, enter the set password and set
init commands, and then enter the enable
remote command..
The modem is not configured
correctly. Modify the modem initialization string
according to your modem documentation.
On power-up, RMC defers
initializing the modem for 30
seconds to allow the modem to
complete its internal diagnostics
and initializations. Wait 30 seconds after powering up the
system and RMC before attempting to
dial in.
After the system is
powered up, the
COM1 port seems to
hang or you seem to
be unable to execute
RMC commands. There is a normal delay while
the RMC completes the
system power-on sequence. Wait about 40 seconds.
New escape sequence
is forgotten. RMC console must be reset to factory
defaults.
During a remote
connection, the user
sees a “+++” string on
the screen. The modem is confirming
whether the modem has
really lost carrier. This is normal behavior.
The message
“unknown command”
is displayed when the
user enters a carriage
return by itself. The terminal or terminal
emulator is including a line
feed character with the
carriage return. Change the terminal or terminal
emulator setting so that “new line” is
not selected.
