Troubleshooting
NOTE:
•
The barcode stuck on the chassis of the WX6103 access controller contains the production and servicing
information. Before you return a faulty access controller for serving, please provide the barcode
information to your local dealer.
•
The LEDs on the standby main control board of the access controller stays off except for the ACTIVE LED,
which has the same status as that of the active main control board. Therefore, you do not need to
consider the LEDs on the standby main control board when troubleshooting a PSU, the fan tray, or the
switch interface board.
Software loading failure
If software loading fails, the system runs in original version. In this case, check if the physical ports are
properly connected:
•
If the ports are not properly connected, reconnect them correctly and restart the loading process.
•
If the ports are properly connected, check the loading process information displayed on the console
terminal for input errors. In case of any input error, restart the loading process with correct inputs.
Input errors include:
•
A baud rate other than 9600 bps selected for BootWare loading using Xmodem.
•
An improper baud rate setting in HyperTerminal
•
A wrong IP address, file name, or TFTP Server work path specified for software loading using TFTP
•
A wrong IP address, file name, username, or password specified for software loading using FTP
If the cause cannot be located, contact your local dealer for help.
Troubleshooting the configuration system
If the access controller passes the POST, the console terminal displays the startup banner and prompt
messages; if the configuration system is faulty, you may see nothing or illegible characters on the console
terminal.
No display on the console terminal
If there is no information display on the console terminal after the access controller is powered on, check
the following items:
•
Whether the PSU LED is solid green
•
Whether all LEDs are off or blinking. If so, the main control board is abnormal.
•
Whether the console cable is connected to the console port of the main control board.
If the cause cannot be located in the steps above, the possible reasons are as follows:
