Connecting Backup Power A Cisco VG224 voice gateway can be installed with optional backup power. Backup power to a DC-powered chassis is provided by a 12-volt battery backup system; see the "Connecting a Backup Battery to a DC-Powered Cisco VG224" section for connection instructions. Backup power to an AC-powered chassis is provided by an uninterruptible power supply (UPS); see the "Connecting a UPS to an AC-Powered Cisco VG224" section for connection instructions. Caution The Cisco VG224 chassis provides inputs for both AC and DC power. Design your installation to use only one type of power. Do not use AC and DC power at the same time. If you do, the unit stops operating, and you must reboot it with only a single power source. The maximum power requirement for the Cisco VG224 voice gateway is 70 W. Connecting a Backup Battery to a DC-Powered Cisco VG224 Connect a 12-volt backup battery to the DC input connector on your Cisco VG224 voice gateway. Before you install a backup battery, be sure to read the installation instructions for the backup battery equipment. Figure 3-15 shows a setup using an external backup battery. Note Figure 3-15 shows one possible setup; please review your backup battery documents before setting up your system. OL-5006-04 Cisco VG224 Voice Gateway Hardware Installation Guide 3-21
