Chapter 1 Overview

Key Features

This section describes the key features of the access point:

• Inline power

• Omni-directional antennas

• Ethernet and serial ports

• Indicators

• Industrial temperature range and UL 2043 rating for 350 series metal case access point

Inline Power

Cisco Aironet 350 series access points receive power through the Ethernet cable, so you do not need to

run a separate power cord to the access point. Plug the Ethernet cable into the Ethernet port on the back

of the access point and plug the other end into one of three possible power sources:

• A Cisco Aironet power injector

• A switch with inline power, such as the Cisco Catalyst 3524-PWR-XL switch

• A power patch panel, such as the Cisco Catalyst Inline Power Patch Panel

Note Cisco Aironet 340 series access points rely on a separate power supply plugged into the power port on

the back of the access point.

Caution Cisco Aironet power injectors are designed for use with 350 series access points and bridges only. Using

the power injector with other Ethernet-ready devices can damage the equipment.

Caution Cisco Aironet Power Injectors are not rated for operation in a building’s environmental air space, such

as above suspended ceilings.

Caution The operational voltage range for Cisco Aironet 350 series access points and bridges is 24 to 60 VDC.

Higher voltage can damage the equipment.

Omni-Directional Antennas

The access point’s omni-directional, 2.2 dBi antennas provide diversity coverage for your wireless LAN

area. Diversity coverage helps maintain a clear radio signal between the access point and wireless client

devices. Just as you can improve signal clarity on your car radio at a stoplight by creeping ahead a few

inches, the access point can improve signal quality by choosing the antenna that is receiving the best

signal from a client device.

Some access points models are equipped with dual reverse-polarity TNC connectors that you can use to

connect to your own antennas for special applications.
