Power Supply Failure; Configuration Terminal Failure - H3C S3600 Series Installation Manual

Power Supply Failure

You can check status of the power system by viewing the PWR LED (POWER) on the front panel. When
the power supply functions normally, the PWR LED stays on. Otherwise, check that:
The switch power cord is correctly connected.
The power input to the switch matches the requirement as labeled on the switch.

Configuration Terminal Failure

After the switch is powered on and the system is normal, the booting information will be displayed on the
configuration terminal. If the configuration system has any faults, there will not be any screen display at
the configuration terminal or the displayed characters will be totally illegible.
Troubleshooting when there is no terminal display
If there is no output information after the switch is powered on, check that:
The power supply is normal
The console cable is properly connected
If no problems are found after the above-mentioned items have been checked, the cause may lie in the
console cable or the settings of the terminal (such as HyperTerminal) parameters. Please perform the
corresponding check.
Troubleshooting when the terminal display is illegible
If there is illegible display at the configuration terminal, the cause might lie in the parameter setting error
at the terminal (such as HyperTerminal). Verify the following terminal parameter (such as hyper terminal)
settings:
Baud rate: 9,600
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
Emulation: VT100.
