Step 8 Put the Panel Back On.
Locate and engage the bottom two hooks on the panel into the housing. Lift up until the top
two hooks on the panel engage and then pull down. Tighten the screw at the bottom of
the panel.
Step 9 Power Up the System.
Turn on the power switch located on the bottom left of the power supply unit. A green LED
will light. If the LED does not light, make sure that the power supply unit is plugged into a
working AC outlet not controlled by a switch. If it still does not light, call your AT&T Hotline
Number or your authorized dealer.
