Before you begin

Each battery stack will provide up to 16 hours of backup power. One battery stack will be connected to the gateway to provide automatic backup. It will need to be replaced with the other standby battery stack as needed during an outage.
Keep a standby rechargeable battery stack connected to a power source to maintain charge. Prepare standby backup rechargeable batteries. Connect the other three rechargeable batteries and the power supply to the other backplane and plug into an electrical outlet (not controlled by a wall switch). Note: To get the best power available, you should plug your battery stack directly into a wall receptacle.

1. Disconnect the existing black power supply from the gateway and wall outlet.
2. Stack the three battery units and the power supply on the backplane.
3. Connect the rechargeable battery stack to the gateway using the supplied power cord.
4. Make sure the battery is on and the gateway is working
