Troubleshooting
This chapter describes how to troubleshoot your gateway.
TIP:
Clean your
g
ateway periodically because the noncompliant operatin
g
environments may cause
g
atewa
y
failures. At the same time, verify the installation environments against the requirements in "Preparin
g
for
installation." Make sure the gateway operates in a compliant environment. Additionally, periodically
perform the power-on test for the spare gateways.
Troubleshooting methods
When your gateway fails, you can use the following methods to troubleshoot the gateway:
• At the CLI, you can use the related commands to display the hardware information, and locate the
hardware failures.
• The MPU provides the LEDs for the fans and cards. You can locate the failures according to the LED
status on the MPU. For more information about the LED status on the MPU, see "Appendix C LEDs."
• The MPUs, LPUs, and service modules of the gateway provide the port status LEDs, with which you
can detect port failures. For more information about the LED status on the MPUs, LPUs, and service
modules, see "Appendix C LEDs."
If you cannot locate failures by following the guidelines in this chapter, contact H3C Support. For contact
information, see "Preface".
Configuration terminal problems
If the configuration environment setup is correct, the configuration terminal displays boot information
when the gateway is powered on. If the setup is incorrect, the configuration terminal displays garbled
text or does not display anything.
No terminal display
If the configuration terminal displays nothing when the gateway is powered on, verify the following
items:
• The power supply system is operating correctly.
• The MPU is operating correctly.
• The console cable has been connected to the console port of the MPU.
• The console cable has been connected to the correct serial interface on the terminal. The serial
interface in use must be the one set on the terminal.
• The console cable is in good condition and operates correctly.
