Chapter 5

The part describes how to remove the fault from the switch.

5.1

The key for resolving the systematic faults is to separate the fault from the system. You

can compare what the system is doing with what the system should do to detect the

fault. You need to check the following subsystems:

Power and cooling systems—power and fan

Port, cable and connection—ports on the front template of the switch and the

cables connecting these ports

Do the following checkups to help remove the fault:

When the power on-off is at the "ON" location, check whether the fan works

normally. If the fan does not work well, check the fan.

If the switch is too hot, check whether the air outlet and air inlet are clean and

then do relative operations in section 2.3 "Requirements for Common Locations".

The working temperature of the switch is from 0 to 40 Celsius degrees.

If the switch cannot be started and the PWR LED is off, check the power.

Do the following checkups to help remove the fault:

If the port of the switch cannot be linked, check whether the cable is correctly

connected and whether the peer connection is normal.

If the power on-off is at the "ON" location, check the power source and the

power cable.

If the console port does not work after the system is started up, check whether

the console port is set to a baud rate of 9600 bps, eight data bits, no sum check bit

and one stop bit.

The LED indicator shows that the switch is running. The following table shows the

indicators of the S2956 switch and their description:
