Chapter 3 Installing Cisco IAD2430 Series IADs
Connecting Backup Power
Connecting Backup Power
Cisco IAD2430 series IADs can be installed with optional backup power. Backup power to a
DC-powered IAD is provided by a battery backup system; see the
“Connecting a Backup Battery to a
DC-Powered IAD” section on page 3-33 section for connection instructions. Backup power to an
AC-powered IAD is provided by an uninterruptible power supply (UPS); see the “Connecting an
Uninteruptible Power Supply UPS to an AC-Powered Cisco IAD2430 Series IAD” section on page 3-34
for connection instructions.
Note UPS functionality is not available on the IAD2435 IAD.
Caution The Cisco IAD2430 series IAD 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.
See Table 3-6 for the maximum power requirements for each Cisco IAD2430 IAD model.
Connecting a Backup Battery to a DC-Powered IAD
Connect a 12-volt backup battery to the DC input connector on your Cisco IAD2430 series router.
Before you install a backup battery, be sure to read the installation instructions for the backup battery
equipment.
Figure 3-30 shows a setup using an external backup battery.
Note Figure 3-30 shows one possible setup; please review your backup battery documentation before you set
up your system.
