I am struggling to find out how to physically reset a PTP850C. Where and how is that done?
Hello Colin,
There is no factory reset button; If you cannot get into the PTP 850C, you’ll need to connect to the MGNT Port using a SPL-ETH-CBL but this is a Ceragon PN. You’ll find a lot of images in the PTP 850 C E User Guide 12.0 that still use Ceragon IP20 images.

However, I’m under the impression a Cambium Networks Protection Splitter Cable is the same.
The IP address of the 850C’s CPU is 192.0.2.1. To connect, you’ll need to setup a new Local Area
Connection with an IP address as follows:
◦ IP address: 192.0.2.3
◦ Subnet mask 255.255.255.240
◦ No default gateway
Then you’ll connect one end of the cable to the Protection port of the PTP 850 unit, for PTP 850C: The Management/Protection port (P6).
Then connect the other end of the cable to the LAN port on your laptop, open up Google Crome or Microsoft Edge to 192.0.2.1
The system will prompt you for a user name and password, the default user name and password are:
Username: admin
Password: admin
Click Apply.
Here is also a snippet from a PowerPoint presentation, though I find it not as easy to understand as the instructions I’ve provided above.

Hi James
I have a IP 20 ceragon
There’s credential issue, I can’t login because password
I tried your solution but didn’t work
How can I do
I emailed ceragon company but they didn’t reply
Please help
Farhad, if it’s a Ceragon radio you have to reach out to Ceragon to help you reset the password so you can regain access to the radio.
Hello Farhad Tajik Did you manage to solve the problem, I have the same one, after factory settings, there is a problem with logging in
Hi James,
I have a problem logging into my 850c. I set up the PC like you said to access the 192.0.2.1 (both ways .3, .10 and sub ending in 240) IP, however it does not work. I have the Prot cable with the Cambium PN as shown in the image. Is the Ceragon PN a different pinout? I have used this cable many times to recover my 820c/s in the past. Any help would be greatly appreciated.

To access Protection NIC on the IP-50C and 850C is the same.
Just to confirm you’ve set you computer up with an IP Address like 192.0.2.2 or 192.0.0.10 for example with a subnet of 255.255.255.0?
It’s the exact same procress as the IP-20S, IP-20C, 820S and 820C.
Check that the cable in your laptop/computer is the altered RJ45 and the unaltered RH45 go’s into P6 Mgnt Port on the 850C.
Also the 850C uses Positive Ground, make sure you’re powering it up correctly.
Yes my computer is set to 192.0.2.98. 255.255.255.0.
Running through a gigabit dumb switch. The modified mimo/prot port on the modified cable has a cat 6 going to the switch and the other end RJ45 is plugged into the unit. MNG end is not used
I am using the 450m PIDU to power it. Is that correct?
