Chapter 2. Logging to the Device
This chapter describes how to configure TCP/IP settings on your computer, and how
to login to the Device. In addition, it briefly describes the layout of the Device’s Web
interface.
2.1 Configuring your computer
To configure the Device via Web UI, you need to properly configure TCP/IP settings
on the computer that you use to manage the Device. To do this, please follow these
steps:
Step 1 Connect the computer to a LAN port of the Device, or connect the computer
to the Device through wireless.
Step 2 Install TCP/IP protocol on your computer. If it is already installed, please
skip this step.
Step 3 Configure TCP/IP settings as Obtain an IP address automatically and
Obtain DNS server address automatically. More information about how to
configure TCP/IP, please refer to the chapter: Appendix A FAQ.
Step 4 Use the Ping command to verify network connectivity between the computer
and the Device. Open the command prompt on the computer, type ping
192.168.1.1, and then press Enter.
A successful ping will look like this:
