7.3 Troubleshooting of Power-supply System Failure
You can judge whether the power-supply system of switch goes wrong via the PWR indicator
on the front panel: PWR indicator being always on means normal operation; please run
checks if the PWR indicator is off:
Whether the power cord of switch is connected correctly.
Whether the power supply matches the required power supply (AC or DC).
7.4 Troubleshooting of Configuration System Failure
After the switch is powered on, startup information will be shown on the configuration terminal if
the system is normal; the configuration terminal may show no information or random codes if the
configuration system goes wrong.
7.5 Troubleshooting of Terminal No-show Fault
If the configuration terminal shows no information after power on, run checks as follows:
Step 1:
Whether the power is normal.
Step 2:
Whether the Console port cable is connected correctly.
Step 3:
If the problem persists after the checks above, it is probably because the provided cable
cannot work or terminal (such as hyper terminal) parameters are set incorrectly. Please
run checks as necessary.
Step 4:
Troubleshooting of terminal showing random codes
If the configuration terminal shows random codes, it is probably because terminal (such as
hyper terminal) parameters are set incorrectly. Please confirm the parameter settings of
terminals (such as hyper terminal): Baud rate 115200, data bits 8, parity null, stop bits 1, and
flow control null, and terminal emulation VT100.
