FAQ
This section describes some of the problems you might encounter when integrating your
appliance into the existing network.
Interface problems
This section contains solutions to problems you might encounter when trying to configure the
appliance through its interface.
Why does using the Back button on my browser take me to the Logon screen?
This is a known issue with the web browser version of the appliance software. Use the appliance
application instead.
I cannot access the Logon screen.
Check the following:
• The appliance is turned on and its software is running — the power LED is lit and the hard
disk drive LEDs are off.
• You used https (not http) in the address field of your web browser. Ensure that your
browser supports Secure Sockets Layer (SSL) encryption and that it is enabled.
• The computer you are using to manage the appliance does not have the appliance configured
as its proxy. If you have a proxy between the management computer and the appliance,
the proxy must be configured with the appliance as its handoff host.
• If you are remotely connected to the appliance (across the network) through the LAN1 port,
ensure that:
• The computer you are using has a working connection to your network, and that it can
reach the same subnet to which the appliance is connected.
• You have used the new IP address that you configured for the LAN1 port, in the URL
field of your web browser. If you have not disabled or deleted the default IP address
10.1.1.108, try using that IP address (
https://10.1.1.108
).
The appliance’s IP address must be suitable for the subnet to which the appliance is
connected. If it is not, use the default IP address and, if that fails, try a direct management
connection.
NOTE: You can obtain a direct management connection through the LAN2 port only if
you are using the appliance in explicit proxy mode and you have not disabled the LAN2
port
• The appliance has a working connection to your existing network, indicated by the NIC
1 network activity LED flashing on the control panel.
If the LEDs are not flashing, ensure that the cable you are using is undamaged and
connected properly to the appliance’s LAN1 port and your existing network equipment.
If you have not used the blue cable supplied with the appliance, ensure that the cable
is a UTP straight-through (uncrossed) network cable.
• If the appliance is operating in explicit proxy mode and you have a direct local management
connection through its LAN2 port, ensure that:
• You have not disabled the LAN2 port. Connect remotely to check this.
