problem then contact HP
The appliance cannot be accessed over
the network.
There are five possible causes for this.
The first is that there may be a TCP/IP address conflict on the network. This can be
checked by examining the LCD of the appliance, which should display the message
"Duplicate network settings detected". If this is the case then the LCD will display an
error message, and the lightbar will blink amber. Check the address of the appliance
with the other computers on the network, and if it matches one of the other machines,
reinitialize the appliance and change the IP address.
The second is due to the fact that the install software must be executed from a
computer on the same network sub-net as the appliance. Check with your network
administrator to ensure this is so.
The third is that if DHCP is being used then the DHCP server may have a problem.
This can be checked by examining the LCD of the appliance, which should display
the message "Network error detected". Check with your network administrator that
the DHCP server is working properly.
The fourth is that if the web administration (or agent install) pages cannot be
accessed using its name or its IP address, the browser may be configured incorrectly.
Check your browser settings. Set the configuration so that all internal addresses used
by the browser are sent directly rather than through the proxy.
In Netscape this is done through the Edit->Preferences... menu choice. Select
Advanced and then Proxies.
In IE4 this is done through the View->Internet Options... menu choice. Select the
Connection tab and check the Bypass proxy server for local (Intranet) addresses
checkbox.
The fifth is that if the web administration (or agent install) pages cannot be accessed
using its name but can be accessed using its IP address, check whether the appliance
has been given the same name as another computer on the network. This would cause
a conflict. Rename the appliance.
Once the appliance has been setup, there is an important consideration to bear in
mind when changing the IP address.
The appliance can use a static IP address, and if this is changed and clients are trying
to communicate with the appliance through routers, then these protected computers
will try to talk to the previous address, and will not receive any answer. Clients on
the same sub-net will be automatically updated.
The solution to this problem, is either to change the IP address of the appliance back
to what it was when the clients could communicate, or to reinstall the client software
