JetDirect card in 4350 not keeping static IP

[TechFee]

Hi, Im having a problem with a LJ 4350N that lost its static IP over the weekend (power loss I believe). I manually reset the IP throught the Jet Direct Menu and it will print a config page that will show the static IP, but I cannot connect to it over the network via the IP in the browser or ping it. If I turn the printer off than back on the IP resets to 0.0.0.0 . I did a cold reset but its doing the same thing. There is a green connectivity light where the network cable plugs in. I've also power cycled the router . Any help or suggestions would be great.

You need to understand your lan subnet before you willie-nillie assign an ip address.

first get a command prompt and enter IPCONFIG /ALL and you get back

For a static IP assignment, you must set the items in bold manually.
Copy all four and then understand that
the IPv4 address must be unique (no one else using it) and
is best if outside your routers DHCP Range (using range 0-254 is silly).
Set the range (in your router) to something like 2-10 and then the
the 4350 IP to something like x.y.z.100 where x.y.z match the first three values
you get from the ipconfig results

Hi, I figured out the issue - there was a faulty port on the patch panel. I ended up re-routing the the printer through a different port on the patch panel to the switch and I got back full connectivity. Not sure why the printer wasn't keeping the Manual TCP/IP setting though when we re-started the printer. It was almost like it was set on DHCP to obtain an IP and it wasnt able to pull, so when I restarted it gave me 0.0.0.0. Neverless its working now. Thanks for the reply. - SGF
