Troubleshooting

22

If you find any problem, please take the following steps to check.

 LED

The POWER LED (Power) is not lit.

  Check if the power cord is disconnected. Please confirm that the power cord is 

securely connected to the power port.

  Is the Ethernet Switch being used at a temperature between 0 and 50

°

C?

    Use the Ethernet Switch in its operating temperature range.
    Note: If used at a temperature out of the operating temperature range, the    
       protection equipment becomes activated and Ethernet Switch power stops.

The Port LED is not lit in Status mode.

  Is the cable correctly connected to the target port?

  Is the cable appropriate to use?

  Is the terminal connected to the relevant port conforming with 10BASE-T, 

100BASE-TX, or 1000BASE-T standard?

  Auto-negotiation may have failed.

  Check the port settings of this Ethernet Switch or the terminal settings.

  Is the correct Port LED display mode selected using the LED display switch 

button?

The Port LED (left) lights in orange.

  Loop is occurring. By removing the loop, orange LED will be turned off.

LOOP HISTORY LED Blinks in green.

  This is to notify that there is a port in which a loop is occurring, or has been 

removed within 3 days.

 Communication is slow.

  Are the communication speed and mode settings correct?

  If the proper communication mode signal cannot be obtained, apply 

half-duplex mode.

  Please reconfirm auto-negotiation setting.
  Do not set forced full-duplex for the equipment that the Ethernet Switch is 

connected to.

  Is not the utilization ratio of the network to which this Ethernet Switch is 

connected too high?

  Try separating this Ethernet Switch from the network.
