Display screen reads dhcp bad conflict - Avaya 5610 IP Phone

Routers have a built in DHCP server to identify each computer connecting to it so traffic can be routed to the correct computer, if more than 1 computer/device shares the same IP you should get an IP conflict not a DHCP error. Routers also normally give out IP addresses from its pool of IP's sequentially and assigns it to expire in 24 hours, so if you reboot your router turn on 1 device grab an IP and then turn that device off, reboot your router and turn a different device on it will get the same IP, now when you turn the other device back on you have a conflict.
If your router has been reset you have to release and renew IP addresses on all your devices to prevent conflicts.

Give it a static address OUTSIDE the DHCP scope.

Sounds more like a bad ethernet cable or bad port on the Iomega. Try using a different cable

Login into tape library console using web browser and disable DHCP and provide Static IP .

Reboot the phone to grab a new DHCP address. If it still does that, then something else has that IP, and the phone has a static as well, so teh phones IP will need to change.

I was having the same problem. Turns out the IP address in the printer was incorrect. Once I changed the IP address the printer works just fine through our network again. Find your IP address off your server and follow these steps:

1. Choose Info on display menu, press okay button
2. Choose Info pages, press okay
3. Configuration pages-printer info, press okay
4. IP address should read: Correct IP Address number should be displayed on screen.

If not follow these steps to change it:

1. Find printer setup on display menu, press okay
2. Go to connection setup-press okay
3. Network setup-press okay
4. TCP/IP setup-press okay
5. Auto should show as “Off”
6. TCP/IP should show as “On”
7. DHCP/Boot should show as “Off”

If any of these are not listed on display correctly press ok, reset to either On or Off and then enter correct IP address.

Press okay button and follow steps on display menu to exit back to main menu display screen.

its shows the conflicts then you give the ip address own donn't give dhcp then conflict are not shows

use static ip higher than the dhcp range so dhcp doesnt assign it to other pc causing ip conflict .. rename computers on network. imaging can cause this issue as the master image can have same comp name assigning it same ip.

You can configure the router to hand out DHCP clients in an assigned range. Set a limit on the DHCP clients, then configure the fiber connection as static and outside of the DHCP range. then they cannot conflict.
