Installation and Configuration 102
Each SP Switch Router Adapter media card is considered a dependent node
for the SP System. Each dependent node has a node_number and other
configuration and status information that is unique to that dependent node.
3.15.1.1 Procedure
The following steps might give you guidance in solving some of the most
common connectivity problems:
1. Check the SP Switch cable for obvious problems such as a loose or
disconnected connector, missing shielding or bent pins.
2. Check the 10Base-T twisted-pair connection between the SP Switch
Router control board and the SP CWS. This connection is normally routed
through an Ethernet hub.
3. If there is no terminal directly attached to the SP Switch Router, check the
SP Switch Router host name from the SP CWS. From the CWS, enter
SDRGetObjects DependentNode node_number reliable_hostname. This will
return the node numbers and the corresponding host names for the SP
Switch Router systems.
4. Test Ethernet connectivity by performing a
ping test from the SP CWS to
the SP Switch Router administrative Ethernet address.
5. Check the status of the SP Switch Router Adapter LEDs.
Use the tables in the "SP Switch Router Adapter LEDs" section in
Appendix C to determine the state of the card.
Generally, RX ST0/ST1/ERR and TX ST0/ST1/ERR indicate a problem.
The problem might be due to connection, configuration, hardware, or
software.
To further test the SP Switch Router Adapter card hardware, you can reset
or reseat the card, and then use the tables under "LED activity during
boot" in Appendix C to interpret the results.
6. From the CWS, use an
Eunfence and/or Estart command to bring the
dependent node back into the configuration.
From the CWS, issue the command
SDRGetObjects switch_responds and
check for correct values. If
switch_responds is 1 or shows up green in
Perspectives, then the dependent node is active again.
7. You may need to log in to the SP Switch Router to perform additional
analysis before determining whether any hardware needs replacement.
8. If problems remain, you will have to contact the next level of Customer
Support for further direction. They may log into the SP Switch Router to
perform additional analysis. If you were directed here by the
