The Dell hardware on which your Lighthouse Standard or Enterprise is built is warranted and serviced by Dell. In the event you need to replace this hardware with a new system from Dell you will need to set Lighthouse up on the new hardware, This is done from a USB key. Booting a fresh box from the USB key will image the machine as a Lighthouse (hardware) device.
- Update the USB Key that was supplied with you Lighthouse Standard or Enterprise appliance with the latest Lighthouse firmware
- Reinstall the Lighthouse firmware on your new Dell hardware
- Restore your configuration from your most recent backup
Updating your USB Key with a newer Lighthouse image
The USB key installs the Lighthouse firmware from a single netflash file: lighthouse-hw.bin This is a standard netflash image file, similar to those that are used to update a device. Because of this, an older USB key can easily be updated to use the most recent Lighthouse firmware in future (when newer versions are released).
- Remove the old firmware update file (
lighthouse-hw.bin) from the USB Key that was supplied with your Lighthouse Standard or Enterprise appliance - Download the newer firmware update file (
lighthouse-x.y.z-hw.bin) from http://opengear.com/firmware/lighthouse/ - Copy this file onto the Lighthouse USB Key and rename it to the expected filename (
lighthouse-hw.bin).

The whole USB Key file is distributed as a disk image that can be written to a USB key via a linux box with a command like:
dd if=lighthouse-boot-usb.img of=/dev/sdc
Note that the image contains a bootsector and partition table, so write it to the whole drive, not to a specific partition.
USB key contents:
- lighthouse-hw.bin
- This is the firmware file that gets installed to the Lighthouse appliance. Update this as needed with new factory images from Engineering or Support.
- install.sh
- This is the script that installs lighthouse-hw.bin to the Lighthouse appliance. It exists as a separate script for ease of maintenance, it should only be changed at the request of Engineering or Support.
- boot.msg
- Splash screen text file that gets displayed to the users on USB boot
- bzImage
- Linux kernel that the USB booted machine runs
- initrdU.gz
- Linux rootfs that the USB booted machine runs
- ldlinux.sys

- syslinux.cfg
- Configuration file for the second stage bootloader
Restore your configuration from your most recent backup
Once Lighthouse has been deployed and the hardware appliance has booted, re-configuration is performed by browsing to the IP address of the NIC on the Dell hardware. The NIC obtains an address using DHCP and has a static IP address of 192.168.0.1
You will be presented with the login screen on your browser:
