You access it with the web browser, but remember that boot time is like 20 minutes so you may have to power it up and wait. it could also have VLANs if not default. The default IP address is 192.168.1.2 and I believe DHCP is disabled by default so you would need to set a static IP address. If you are really struggling connect a serial cable to the maintenance port and monitor the output to see the IP address to connect to.
