Troubleshooting
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.
Network
Management
Access
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.
Pin Assignments
for Serial Port
Connections
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.
