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.

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.

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.

•
The appliance is turned on and its software is running — the power LED is lit and the hard
disk drive LEDs are off.

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.

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.
