The part describes how to remove the fault from the switch.
1. Fault Separation
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 detec
tthe 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
5.1.1 Faults Relative with Power and Cooling System
Do the following checkups to help remove the fault:
When the power on-off is at the “ON” location, check whether the fan works n
ormally. If the fan does not work well, check the fan.
The working temperature of the switch is from 0to 40 Celsius degrees.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”.
If the switch cannot be started and the PWR indicator is off, check the power.
2. Faults Relative with Port, Cable and Connection
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 supply and the po
wer cable.
If the console port does not work after the system is started up, check whethe
rthe console port is set to abaud rate of 9600 bps, eight data bits, no sum ch
eck bit, one stop bit and no traffic control.
