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 extender does not power off any interfaces to conserve power when AC 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
CG-NMS firmwa
re upgrade option.
The firmware upgrade is executed in background and an output message is generated in the CG-NMS
when th
e BBU firmware upgrade is complete. During the firmware upgrade, you can use the CG-NMS
to view the state of the BBU firmware upgrade.
