Battery Backup Unit

A selection of the WPAN advanced range extender models support one battery backup unit (BBU),
which provide power to the rang extender if the AC power supply fails or is not available. For more

The battery backup unit (BBU) provides the WPAN range extender with an emergency power source if
the AC power source is unavailable. The unit is mounted in the range extender housing.

Table 3-2describes the BBU model.

BBU Model Description

CGR-BATT-4AH Battery backup unit, capacity = 48 Watt-hours

BBU Status

The BBU is automatically enabled and begins supplying power when the range extender detects that
power is not being receiv ed from the A C po wer supply. The BBU continues to supply power to the range
extender until at least one of the following conditions is met:

• BBU is completely discharged

• AC power to the range extender is enabled

• BBU is disabled via the Connected Grid Network Management System (CG-NMS) software

application.

Range Extender Configuration

The range extender software configuration is not impacted when the range extender switches from AC
power to BBU power.

Range Extender Interface Operation

When the BBU is operating and powering the range extender, the range extender operates and performs
normally. The range e xtender does not po wer off an y interfaces to conserve power when A C power is not
available, and the range extender is being powered by the BBU.

BBU Firmware Upgrade

It is only possible to use the CG-NMS to upgrade the BBU firmware and to show information about the
BBU firmware upgrade.

To upgrade the BBU firmware and to show information about the BBU firmware upgrade, use the

BBU Configuration during Transportation

29/OCT/2014 REVIEW DRAFT — CISCO CONFIDENTIAL

BBU Configuration during Transportation

The BBU configuration during transportation is controlled by a dedicated bit in the BBU NVRAM
register called the Transportation bit or (T-bit).

The T-Bit is set at the factory and is used to place the BBU in a disabled (lo

Note If the BBU is disabled due to being < 5% capacity, it will be

enabled automatically when AC power resumes. If the customer
disables the BBU, the customer must enable the BBU manually.

Disabling and Enabling the BBU in the Range Extender

In normal operating mode (T-bit is off), the BBU automatically begins to supply power to the range
extender when it detects that power is not being received from the AC power supply. You may wish to
disable and enable the BBU for the following reasons:

• To inhibit the BBU discharge during storage, shippi ng or t ranspo rtation in order to preserve battery

life.

• To replace the battery in an installed and operating range extender.

Installing a BBU in the Range Extender

A BBU can only be installed in the WPAN range extender by a Cisco trained technician. Contact your
Cisco representative for support.

Range Extender Power Path Selection

During normal operation, the range extender is powered by the integrated AC power supply. The BBU
enters discharge mode and begins providing power to the range extender when the AC power is
interrupted outside a range of 85V to 250V for more than 20 ms. The BBU charges or discharges only;
it does not support both simultaneously.
