Check the installation instructions for additional information on setting the DataRate parameter.
This message is relevant for 4-Mbps and 16-Mbps operation only.
IBMTRPO-xx-225:
A network protocol error occurred while attempting to operate the adapter in full-duplex mode.
Explanation: The adapter was unable to successfully communicate with a token-ring switch when attempting to open
for full-duplex operation.
User Action: Check that your full-duplex switch is functioning correctly and that the adapter is correctly connected to
it. If this problem persists, contact your customer service center.
IBMTRPO-xx-226:
Unable to automatically change to xx Mbps operation. Please reboot the computer.
Explanation: The adapter attempted to open at one speed, but found the Token Ring operating at another speed.
The configuration parameters used during initialization processing, notably the maximum frame size, preclude reliable
operation at the new speed, so all additional attempts to open the adapter will be rejected. Rebooting the computer
allows the new speed to be factored into the initialization processing without requiring a configuration change in most
cases.
User Action: Shutdown and restart the computer. Normally, no explicit configuration changes are required to begin
operating at the current operational speed of the Token Ring. Optionally, you might be able to change the value of the
configuration parameter that specifies the maximum frame size to a value of 4500 or less to eliminate needing to
reboot the computer for a similar situation in the future.
IBMTRPO-xx-227:
The adapter opened for Token Ring, xxx Mbps, half duplex.
Explanation: Information only.
User Action: None.
IBMTRPO-xx-228:
The adapter opened for Token Ring, xxx Mbps, full-duplex.
Explanation: Information only.
User Action: None.
IBMTRPO-xx-233:
Adapter analysis code is xxx.
Explanation: Information only.
User Action: None.
IBMTRPO-xx-234:
Adapter full-duplex operation has now been activated.
Explanation: Information only.
User Action: None.
IBMTRPO-xx-304:
Adapter is disconnected from the media.
Explanation: The media network is not functioning correctly.
User Action: Verify that the cable is securely attached to both the adapter and the token-ring network. Run
diagnostics if the problem persists. You might need to contact your local administrator to ensure that the cabling in the
building is intact and that the network concentrator to which you are attached is operational. If the error persists, try
using a different cable.
