- load the GUI firmware
- configure the "Servers" section with your fixed Sunray
server IP address (or sunrayservername.domainname) if the
local DHCP/DNS setup will resolve the address of the
sunray server on your subdomain)
- leave the IP set to "DHCP" in the "TCP/IP" section
of the GUI firmware setup
- set the firmware password to avoid tinkering
You can now plug the unit in anywhere on your network and
- pick up its IP, netmask, and default router from your
IT group's standard DHCP server
- resolve the server IP via DNS (if you didn't use a
hardcoded IP number)
- drill through to your designated sunray server via its
There is still a tiny bit of initial setup to load the GUI
firmware and input two (sunray and firmware) server addresses,
but after that the units should be fully plug and play.
I hope I haven't misunderstood your requirement.
