Appendix A Troubleshooting
Routine operation of the Safari Network should generally
be straightforward; however, problems with
communications can sometimes occur, and these
problems will need to be diagnosed and corrected. This
chapter discusses potential problems that may be
experienced by network users, along with the possible
causes and the appropriate corrective actions.
Types of Problems
The types of problems that may occur in the network are:
A radio is not communicating at all (see below).
A radio is communicating, but there are errors with—or
omission of—data (see page A-5).
A radio is communicating, but the signal-to-noise (S/N)
level is less than 3 (see page A-6).
If a radio is not communicating
Confirm that the radio is not communicating (using the
configuration software on the NCU) by listing all units
logged onto the network:
1. Launch a terminal program (such as HyperTerminal).
If you have reserved COM2 on the NCU as a Network
Management port, go to Step 5.
2. Power up the NCU through the Port Expander. Within
10 seconds, type the word “admin” and press the
Enter key.
3. When the NCT SR-7100 Admin Page appears, select:
1. Network Configuration Menu.
