Introduction This appendix describes some of the actions you can take to correct problems you
may be having with your PathBuilder S21x switch.
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.
Figure C-1. Network Configuration
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:
Remote
Network
Local
PB S200 Network Remote
PB S200
Your Local
Network
(905) 555-6666 (905) 555-1234
10.10.10.1 10.10.20.1 10.10.20.2
10.10.30.0
10.10.10.0
Step Action
1Ensure 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.)
2If 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.
3If 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.
Troubleshooting Your PathBuilder S21x Switch C-3
While Setting Up Your Configuration
Pinging the Local
LAN Interface From the workstation or PC connected to the same local LAN segment that the
PathBuilder S21x switch is connected to, ping the LAN interface of the PathBuilder
S200 series switch (“ping 10.10.10.1”). The LAN LED should flash whenever a Ping
packet is received.
If the LAN LED does not flash, check the configuration of the PC and the LAN
connection and do the following:
If the LAN LED does flash, but there is no ping response, do the following:
Step Action
1Check the IP address and IP address mask of your PC or workstation,
making sure that they are set to valid address and mask appropriate for
your local subnetwork. (In the above example, the IP address of the PC
must be set between 10.10.10.2 and 10.10.10.254) and the address mask
must be set to 255.255.255.0).
2Check the statistics of the LAN port (port 5) of the local node, making
sure that the “Carrier” says “Present”. If the “Carrier” field displays
“Lost”, there is a problem with your LAN connection and you should do
the following:
• If you are using a BNC connection between your workstation/PC
and the PathBuilder S21x switch, make sure that you put in the 50
Ω termination resistors at both ends of the line.
• If you are connecting your LAN using the 10BaseT and a 10BaseT
Hub, check the display at the Hub to ensure that the connection
between PathBuilder S21x switch and the Hub is correct. (Most
Hubs have LEDs that stay ON when the carrier is detected).
• Change the RJ45 twisted pair cable between PathBuilder S200
series switch and your Hub as it may be damaged. A straight-
through 10BaseT cable is generally required between PathBuilder
S21x switch and a 10BaseT Hub.
If there is only a single PC or workstation connecting to the PathBuilder
S200 series switch, and you are not using a 10BaseT Hub, ensure that
you have used the RJ45 crossover cable, shipped with your PathBuilder
S21x switch, to connect between the PC and the PathBuilder S200
series switch.
Step Action
1From the CTP, check the statistics of the LAN port (Port 5) (select menu
option Statistics, and select port 5) while sending ping packets.
2Confirm that the Rx Frame Count, in the Data Summary, increases as
the ping packet arrives.
3Check the Tx Frame Count field in the Data Summary part of the LAN
port statistics. If the field increases for every ping packet it receives, the
LAN and the configuration should be working.
C-4 Troubleshooting Your PathBuilder S21x Switch
While Setting Up Your Configuration
Pinging the Local
WAN Interface Once you are successful in getting ping responses from the local LAN interface, you
can proceed to ping the local WAN interface (“ping 10.10.20.1” in the example). If
there is no response, then check the following:
4If the RX Frame count increases, but the Tx Frame Count does not, the
problem is most likely due to misconfiguration in the IP router Interface
#1. Make sure that the IP addresses and IP address mask (select menu
option Router -> IP Interfaces -> Interface 1) are set properly.
Step Action
Step Action
1Confirm that the IP interfaces (either 5 or 6) of the WAN link that you
are trying to ping are configured for Enable. (Select menu item
