Cannot access login screen SMC D3G-CRR

I have a SMC D3G-CRR that I cannot access the login screen at all.  No response from it.

I get DHCP assignment from it of 10.1.10.11, and windows ipconfig says the gateway is 10.1.10.1.  But trying to connect to 10.1.10.1 gets no response.

I was able to over a year ago, but I can't access it now.

How do I get into it?  Is there any sort of console login I can use instead of TCP/IP?
