Appendix A: Troubleshooting

Refer to the Quick Installation Guide for a more detailed listing of troubleshooting procedures. However, if you have trouble making a connection to the agent module, then please refer to the following section.

Console Connection

If you cannot access the on-board configuration program via a serial port, be sure to have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 19200 bps. Also check that the null-modem serial cable conforms to the pin-out connections provided in Appendix B. If you forgot or lost the password, contact Accton Technical Support for help.

In-Band Connection

You can access the management agent on the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software such as AccView. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Note: Up to four Telnet connections are supported.

Upgrading Firmware via the Serial Port

You can upgrade system firmware by connecting your computer to the serial port on the agent module, and using a console interface package that supports the XModem protocol. (See Making Connections for System Configuration on page 1-2.)

1.Restart the system by using the Restart System command.

2.When the system initialization screen appears as shown below, press “Ctrl+G” to download system firmware, and then indicate the code type (1: Runtime, 2: POST, 3: Mainboard).
