Over the weekend we lost power to the OS7100 and this morning it cannot be found on our network. It was set as a static address on our network and now I cannot locate it using wireshark any other IP scanner so far.
I have a Link light on the MP10 module so it appears to be online but without the IP I don't know how to access it as DM won't work.

We only have IP phones so can't access system via phones either.

If I need to I will reset the full system but I'm hoping there is some other method to regain acess.

Well right after posting this I deleted the reservation in our DHCP server and the phones came up almost immediately. What is strange is that the OS7100 IP is still the same so in theory deleting the reservation should not have had any effect.
