Refer to the AT-FH812u and AT-FH824u Installation Guide for a more detailed listing of troubleshooting procedures. However, if you have trouble making a connection via Telnet or accessing the web or SNMP agent, then please refer to the following section.

You can access the hub from anywhere within the attached network. However, you must first configure the hub with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the console interface (with Telnet), the web agent (with a browser), or the SNMP agent (with network management software), check to see if you have a valid network connection. Then verify that you entered the correct IP address from your location. Also, be sure the port through which you are connecting to the hub has not been disabled. For detailed information, see Configuring Port Parameters on page 16. If it has not been disabled, then check the network cabling that runs between your management site and the hub.

DB9 Serial Port Pin Description. The DB9 serial port on the back panel is used to connect the hub to a management device. The on-board menu-driven configuration program can be accessed from a terminal, a PC running a terminal emulation program, or from a remote location via a modem connection. You can use the management port to configure port settings (enabled or disabled), or to update device firmware.
