Basic Troubleshooting
205Network Storage Router M2402 User Guide
Verifying Serial Port Configuration
Verify the configuration of the terminal or terminal emulation program.
If problems persist, verify the cabling.
If a valid Ethernet IP address is configured, serial configuration settings can also
be set via Telnet.
Verifying PRLI Data
The router returns the PRLI (preliminary login) response data as specified in
Table 6.
In the default configuration, the router returns PRLI Data (PRLI Accept Payload)
with the Target bit SET and the Initiator bit CLEAR. However, some
configurations require the Initiator bit be SET, such as in router-to-router
configurations. See the FC configuration sections of Chapter 4, “Visual Manager
User Interface,” or Chapter 5, “Serial/Telnet User Interface,” for information.
