Quidway S3526 Ethernet Switch

7.1 Power System Failure

You can check and verify whether power system of S3526 switch has failed by

observing the power indicators on the front panel. The POWER indicator is always on

when the system is normal; if the indicator is off, please check that:

Whether the switch power cords are correctly connected.

Whether the power input to the switch matches the requirement as labeled on the

switch.

7.2 Configuration System 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 fault, there

will not be any screen display at the configuration terminal or the displayed characters

will be totally illegible.

I. Troubleshooting when there is no terminal display

If there is no output information after the configuration is powered on, please check

that:

whether the power supply is normal

whether the console cables are connected correctly

If no problems are found after the above-mentioned items have been checked, the

cause may lie in the console cable or the setting of the terminal (such as HyperTerminal)

parameters. Please perform the corresponding check.

II. Troubleshooting when the terminal display is illegible

If the configuration terminal display is illegible, the cause might lie in the parameter

setting error at the terminal (such as HyperTerminal).

Please confirm the parameter setting at the terminal (such as HyperTerminal): set the

baud rate to 9,600, data bit to 8, parity check to none, stop bit to 1 and flow control to

none. Select the terminal emulation as VT100.
