Installation
The MicroCell is a plug-and-play device that installs in around 20 minutes. Connecting the MicroCell to your pre-existing
equipment is straight forward, but be sure to read the cabling instructions carefully before making connections.
Note: Before starting, you can view AT&T’s online MicroCell demonstration at att.com/3GMicroCell.
Step 1. Ethernet Cabling
There are three commonly used Ethernet cabling options for installing your device and a fourth that is seldom used. Which
one is right for you, depends on the equipment setup you have.
• Option A: DSL/Cable Service with Router – You have DSL/Cable service, a broadband modem, and a router that supports
a PC network. See Ethernet cabling instructions on this page.
• Option B: DSL/Cable Service with Modem – You have DSL/Cable service and a broadband modem that supports a
single PC. See page 8 for Ethernet cabling instructions.
• Option C: DSL/Cable Service with Gateway – You have DSL/Cable service and a broadband gateway that supports a
PC network. See page 9 for Ethernet cabling instructions.
• Option D: DSL/Cable Service with Router (Bridge Mode) - You have DSL/Cable service, a broadband modem in bridge
mode and a router with a PPPoE termination (this configuration is seldom used). See page 10 for Ethernet cabling
instructions.
Option A: DSL/Cable Service with Router
Place the MicroCell upright, near the modem and router.
1. Disconnect the Ethernet cable from the modem (see dotted line), while leaving the other end connected to the router.
2. Reconnect the Ethernet cable to the black connector marked Computer on the MicroCell.
3. Find the yellow Ethernet cable that came with the MicroCell and connect it between the yellow connector marked
Ethernet on the MicroCell and the Ethernet port on the modem.
4. Go to Step 2. Startup.
Note: It is essential for the router to be connected to the PC port to ensure the best quality of service on the MicroCell.
