Caution for
GX6000-series
appliances
Do not turn the appliance off or remove power from the appliance at any time during the
reinstallation process. Removing power can corrupt the installation process and
permanently damage the appliance, resulting in a situation whereby the appliance must
be returned to the factory.
If you want to turn the appliance off, wait until after you see the unconfigured login
prompt.
Reinstalling the
appliance software
using a PXE boot
server
To reinstall the appliance software:
1. Turn the appliance off.
2. Insert the Proventia Network Intrusion Prevention System Recovery CD into the CD-ROM
drive of the PXE boot server, and then restart the PXE boot server.
3. If you are prompted to do so, type
bootserv and press ENTER.
The PXE boot server displays the following messages:
***You may now boot your Proventia GXxxxx via the network***
***Starting Terminal Emulator***
***Press Control-G to Exit and Reboot***
Note: The PXE boot server now acts as a terminal emulator for the appliance and
displays the console output of the appliance.
4. Turn on the appliance.
The PXE boot server displays boot process messages, and then displays the following
prompt:
Press L to boot from LAN, or press any other key to boot normally.
Important: The installation process allows only five (5) seconds for you press L to
boot from LAN. If you do not press L within this time period, the appliance boots as
usual, and you must restart the appliance.

Turn off the appliance, and then connect the computer (PXE server)
directly to the appliance with the provided cables. See diagram below.
Connect the null modem cable to the devices as follows:
• On the computer (PXE server), use the port labeled COM1.
• On the appliance, use the port labeled Console.
Connect the Ethernet cable to the devices as follows:
• On the computer (PXE server), use the Ethernet port.
• On the appliance, use the left Management port labeled 1.
Note: Connecting to the computer (PXE server) to the appliance disables
the appliance-Internet connection. When you finish the reinstall process,
you must re-establish the Internet connection to retrieve appliance
updates.
Important: If you are running multiple PXE servers on the network, then
you need to disconnect them prior to running the Proventia Network IPS
reinstallation. You can verify that you are accessing the correct PXE server
by the message displayed in Step 5.
