Getting Started with the Graphical User Interface (GUI) 41
Software Release 2.6.1
C613-02039-00 REV A
Problem The GUI is behaving inconsistently, or you cannot access some pages.
Solution ■Delete your browser’s temporary files (see “Deleting Temporary Files” on
page 40) and try again.
■Check that you are trying to access the GUI from a supported operating
system and browser combination. See “Browser and PC Setup” on page 22
for more information.
■Check that JavaScript is enabled.
Problem The GUI does not seem to configure the switch correctly.
Solution ■Use the buttons on the GUI pages to navigate, not your browser’s Back,
Forward or Refresh buttons. The GUI’s navigation buttons perform aspects
of the configuration.

Problem No traffic is passing through the switch to or from the LAN, the DMZ or
both.
Solutions ■Check that the switch’s link to the LAN is functioning, by checking the
interface status (Monitoring) and that the link LED is lit. If the LED is not
lit, or the appropriate interfaces do not have an status of “active”:
• Check that the port is enabled (Configuration > Port > Settings)
• Check that the IP address of the interface is still valid.
• Check that the cables are connected correctly and function correctly.
■Check the RIP configuration (Configuration > Internet Protocol > RIP).
• Check that the RIP neighbour can reach the switch, by pinging the
switch from the RIP neighbour.
• Any password and authentication settings must be configured on the
neighbour as well as on this switch.
■Check that the switch is passing the correct DNS information to hosts on
the LAN, if the switch is a DHCP server. If the switch acting as a DHCP
client as well, and therefore is passing on DNS information from another
DHCP server, check that this DHCP server is providing the switch with the
correct information.
