6.1 Monitoring the Switch
Although the S9500 series have undergone a comprehensive and strict factory test
before delivery, there might be some fault occurring due to improper installation. This
chapter describes how to troubleshoot the S9500 series.
6.1.1 Troubleshooting Console Terminal
If the system is normal after the Switch is powered on, the booting information will be
displayed on the Console terminal. If the configuration system has failed, the Console
terminal may give illegible output or nothing at all.
1) The terminal gives no displays after the Switch is powered on.
In this case, you should check if:
z The power system is working normally.
z The SRPU is working normally.
z The Console cable has been connected to the Console port on the SRPU.
If no problem has been found in the above checking, the symptom is very likely caused
by the errors listed below.
z The Console cable is not connected to the right serial port, that is, the port in use is
not the one configured on the terminal.
z There are Console terminal parameter errors. (According to the parameter setting
requirements, you should set the baud rate to 9600, data bits to 8, parity to None,
stop bits to 1, flow control to None, and select VT100 as terminal emulation.)
z The Console cable is not in good condition.
2) The terminal gives illegible characters.
This symptom is very likely caused by a Console terminal setting error. In this case,
check that you have set the baud rate to 9600, data bits to 8, parity to None, stop bits to
1, flow control to None, and select VT100 as terminal emulation.

It keeps ON if the power input is normal and the PSU switch is at ON
position. It keeps OFF if the power input has failed or if there is no
power input at all.
