Power; External Antenna - Cisco Aironet 1400 Series Hardware Installation Manual

Chapter 1 Overview

Power

The bridge is available in two output power versions to support international regulatory regions:
•
•
The bridge receives inline power from the Cisco Aironet Power Injector LR (hereafter called the power
injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the
bridge. The power injector is an external unit designed for operation in a sheltered environment, such as
inside a building. The power injector also functions as an Ethernet repeater by connecting to a
Category 5 LAN backbone and using the dual-coax cable interface to the bridge.
The power injector uses an external 48-VDC power module and after detecting the presence of the
bridge, injects the DC voltage into the dual-coax cables to power the bridge.
Note The power injector and the power module should not be placed in an outdoor unprotected environment.

External Antenna

The bridge is available with an N-type RF connector on the front of the unit (see
external 5.8-GHz antenna. The supported external antennas connect to the bridge antenna connector
using the antenna's 4.9-ft (1.5-m) coax cable.

To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must

be professionally installed.
Some international regulatory regions may restrict the use of external antennas.
