It is recessed to prevent accidental resets. To reboot the modem, press and hold the indented Reset button for three to four seconds.

ETHERNET - Connects to the 10/100/1000 Ethernet ports on your computer. Devices should only be plugged into Ethernet port 1, because only one port is active. Therefore additional devices plugged into the other ports will not receive Internet access. CABLE - Connects to the cable wall outlet. POWER - Connects the modem to the power cord.

MAC Address Click to enlarge.		MAC addresses are written as 12 digits containing both letters and numbers (0-9, A-F). A MAC address is unique. The first six characters of the MAC address are unique to the manufacturer of the device. This information is usually found on a sticker located on the bottom of the modem.
