Note
If you are using an older LITE(2)/LITE(2)+, you may have to attach the unit's WAN port
directly to your PC using a crossover cable for the first stage of the recovery procedure.
The Netflash program prompts you to switch the cable to the LAN port/switch using a
straight through for the second stage of the recovery procedure.
Log in to your PC with administrator privileges (2000/XP/NT4 only).
Ensure there are no DHCP server programs or services (Start -> Run -> Open:
services.msc) running on your PC.

Note
If the recovery procedure fails at or after Assigning IP address.., but the Heart Beat/H/B
light is flashing, the unit may have become uncontactable due to bad configuration. If this
is the case, hit the Reset/Erase button twice within 2 seconds to restore factory default
configuration, power off the unit and restart the recovery procedure from the beginning.
