C-2 Troubleshooting Your PathBuilder S21x Switch
While Setting Up Your Configuration
While Setting Up Your Configuration
Introduction
This section describes the ways you can use to isolate problems that you may
encounter while setting up a PathBuilder S21x switch to pass IP traffic over PPP
links. For discussion purposes, the following network configuration (shown in
Figure C-1) is assumed.
Note
The configuration of the local PathBuilder S21x switch and the number to call
can be obtained by defaulting the node—selecting “Default Node” from the
CTP’s Main menu.

Note
The IP addresses used in this configuration example are for illustration purposes
only. You must obtain registered IP addresses from your network administrator
or your Internet Service provider, and configure them in your PathBuilder S21x
switch before connecting to the Internet or Intranet.
Checking the
Physical
Connection
Use these procedures to check your PathBuilder S200 series switch connection and
interface:

Step Action
1
Ensure that the STS LED is ON to confirm that power is connected and
that the unit is working. (Other LEDs may be ON or blink occasionally.)
2
If the STS LED flashes continuously for more than 30 seconds after the
power is applied, the software image in the flash is corrupted and the
node is waiting for software to be coldloaded. Refer to the Software
Installation and Coldloading Manual
for more infromation on cold-
loading software.
3
If you are connected to the control port using an async terminal, (9600
bps, 8 bits, no parity), type “AT <CR>” and confirm that the Path-
Builder S200 series switch outputs “OK.” Then log into the CTP.
