If You Have Trouble with a Terminal or Modem Connection
If you have followed the terminal connection instructions on the previous pages and you do not
get a prompt, try the following procedures in sequence until you do get a prompt:
Note
A console session cannot be started until the bridge passes its self-test. Before
trying the procedures listed below, make sure the bridge’s ports are properly
terminated (viable networks or loopback connectors are properly attached), and
that the bridge has passed its self-test (the Self-test LED is OFF).
1. Connection Reset Procedure:
1. Detach, then reattach the console or modem cable to the bridge.
2. Press RETURN several times for the prompt.
2. Cycle Power Procedure:
1. Cycle power on the bridge by unplugging the power cord and plugging it in again.
2. When the power-on self-test is done, press RETURN several times for the prompt.
3. Adjust Baud Rate Procedure:
1. Temporarily set the baud rate in the terminal’s own configuration to 2400.
2. Press RETURN several times for the prompt.
3. Set the bridge’s baud rate to the desired rate (for example 9600) by using the console’s
Speed command (see “Console Commands” later in this chapter).
4. Set the terminal’s configuration to this new baud rate, and press RETURN again for the
prompt.
4. Test Console Port Procedure:
1. Detach the console cable from the bridge. Attach the console port’s loopback connector
to the bridge. (HP part no. 5062-3355––see appendix A, “Cables and Connectors”.)
2. Cycle power on the bridge by unplugging the power cord and plugging it in again. As
part of its power-on self-test the bridge tests the console port.
3. If the test passes (the Fault LED goes OFF), the console port should be functional.
a. Remove the loopback connector and cycle power again.
b. Reattach the console cable to the bridge. Press RETURN several times for the
prompt.
4. If the Fault LED remains ON, the bridge is faulty and must be replaced.
