Troubleshooting and repair
Viewing diagnostics
You can view the diagnostics that are output by the 3100
system through a local or remote diagnostic session.
Note that maintenance commands are not available
through a diagnostic session. See Using maintenance
commands (p. 162).
Starting a local diagnostic session
To start up a local diagnostic session, you need
•
one Male “DB9 to RJ45” connector
•
one Female “DB9 to RJ45” connector
•
one CAT5 patch cord
•
communication application (such as Hyperterminal)
•
a computer or laptop.
Since you are running a local diagnostic session you do
not require a modem. In the following procedure,
Hyperterminal is the communications application.
To collect diagnostic information
1. Connect an RS-232 cable between the lower DB9
port on the front panel of the controller and a COM
port on a laptop or computer.
Do not leave the RS-232 diagnostics cable
disconnected from the computer or laptop COM
port during system bootup (that is, either connect
the cable to the PC or disconnect it from the
diagnostics port).
2. From the Start menu, click Programs, click
Accessories, click Hyperterminal, and then click
Hyperterminal.
