Hardware Troubleshooting
Status Indicator

The LED status indicator displays the general operating state of the OkiLAN 6120e. During normal operation, the red LED is off and the green LED is on, indicating that the OkiLAN 6120e is functioning properly and the presence of the network is detected.

The following list describes LED displays that indicate problems, as well as possible solutions:

LED Display
Green indicator flashing very rapidly
Problem
The OkiLAN 6120e has not detected the presence of a network cable.

Solution
a) Unplug the OkiLAN 6120e power adapter from the wall outlet. Remove the network cable. Plug the network cable back in until you hear a positive click. Check the other end of the cable in the same manner. Plug the OkiLAN 6120e back in. If it does not detect a cable, continue below.

b) Verify the cable is a 10/100Base-T cable and it has an RJ-45 end. The network cable must have a cat-3 or higher rating. Silver Satin or flat ribbon cable is not adequate.

c) Connect to a network that a currently working PC or print server is using. If the OkiLAN 6020e is still unable to detect the network cable, contact Technical Support for assistance.

LED Display
Green indicator is flashing slowly (1 timer/sec); the OkiLAN 6120e is trying to print a job.
Problem
The printer is malfunctioning or does not have sufficient paper or toner.
Solution
Verify that the printer is not showing any errors and has sufficient paper and toner.

LED Display

Red indicator stays red for more than 30 seconds.
Problem
The printer server has failed the Power On Self Test.
Solution
The OkiLAN 6120e will try to print a configuration sheet on the printer with more information.

Failing the self test can be caused by any of the following:

a) The printer is malfunctioning. Unplug the OkiLAN 6120e from the printer and unplug the power adapter. Reconnect the OkiLAN 6120e and the power adapter. If the OkiLAN 6120e still fails the self test, continue below.

b) The OkiLAN 6120e power supply has failed or there is a hardware problem. Contact Okidata Customer Support for replacement information.

LED Display
The red and green indicators are alternately flashing for longer than two minutes.
Problem
The OkiLAN 6120e is in firmware download mode. This means it is waiting for new firmware to be sent before it will continue functioning normally.
Solution
If the OkiLAN 6120e was purposely put into firmware download mode, finish the download with the proper update utility. Contact our web site at http://www.okidata.com to download the utility.
