Chapter 5

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

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:

Connection of the power supply



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



cables connecting these ports

5.1.1

Do the following checkups to help remove the fault:

Make sure that the power line is reliably connected and that the power supply



provides power normally.

Check the environmental conditions and make sure that the switch is put at a



working location with a temperature of 0 to 45℃.

 If the power supply of S2510-B provides power normally, power indicator PWR is

on, or indicator SYS flickers.

5.1.2

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 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, one stop bit and no traffic control.

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

S2510-B switch and their description:
