Troubleshooting Troubleshooting methods When your HP 6125 blade switch fails, you can use the following methods to troubleshoot the blade switch: • At the CLI, use the related commands to display the system running information, and locate the failures. • Locate the failures according to the LED status on the blade switch. For more information, see "LEDs." • View the system and port operating state through the OA module on the enclosure. For more information, see HP BladeSystem Enclosure Setup and Installation Guide. NOTE: If you cannot locate failures by following the guidelines in this chapter, contact HP Support. Software failures If the configuration environment setup is correct, the configuration terminal displays boot information when the blade switch is powered on. If the setup is incorrect, the configuration terminal displays nothing or garbled text. No terminal display If the configuration terminal displays nothing when the blade switch is powered on, verify the following items: • The Health LED is green, which indicates that the system is operating properly. • The console cable is properly connected. If no problem is found, the following reasons may apply: • The console cable is connected to an incorrect serial interface (the serial interface in use is not the one set on the terminal). To solve this problem, select a correct serial interface. • The console cable fails. To solve this problem, replace the console cable. Garbled terminal display If terminal display is garbled, verify that the following settings are configured for the terminal: • Baud rate-9,600 • Data bits-8 • Parity-none • Stop bits-1 • Flow control-none 18
