Bridge and Access Point

3CRWEASYA73 / WL-575

The 3Com WL-575802.11a OutdoorBuilding-to-BuildingBridge and Access Point provides IEEE 802.11a or 802.11b/g wireless access to the network. The bridge offers a fast, reliable, and costeffective solution for connectivity between remote Ethernet wired LANs or to provide Internet access to an isolated site.

Power is supplied by Power Over Ethernet (PoE) using a:

3Com propriety PoE Injector (output: 48V 60W)

Feature

Description

 

 

Console Port

Connect the console cable (included) to the RS-232console port for accessing the

Connector

command-lineinterface.

POE Connector

The PoE port serves two functions, one in providing a means to supply power to the

 

unit and two as an Ethernet port providing access to the web browser interface.

 

The Ethernet port provides a 10/100BASE-TXEthernet connection to a 3Com Wireless

 

LAN switch. The connection can be direct to a 3Com switch or indirect through an

 

intermediate Layer 2 or Layer 3 network.

 

Use a standard Category 5e cable or better with straight-throughsignaling and

 

standard RJ-45connectors to connect the bridge to the switch on the network.

 

The bridge should be powered via proprietary Power Over Ethernet (PoE) power

 

injector.

LEDs

The LEDs indicate power and activity. See “Checking the LED Indicators” on page 11

 

for details.

Antenna Connectors

Three N-typefemale antenna connectors allow you to connect antennas that operate

 

in 2.4 GHz and 5.0 GHz bands.

Water Tight Test

CAUTION: Do not remove or loosen this screw. Doing so could lead to damage of the

Point

unit.

2

Grounding Point

In the event of electrostatic shock the connection of an insulated cable to the

 

grounding point to an earthed point protects the unit from excessive electrical

 

discharge. A grounding screw is provided in the package contents.

Integrated Antenna

Built in 5.0 GHz flat panel high-gainantenna.

 

 

Observing Safety Precautions

This equipment must be installed in compliance with local and national building codes, regulatory restrictions, and FCC rules. For the safety of people and equipment, only professional network personnel should install the bridge.

WARNING: To comply with FCC radio frequency (RF) exposure limits, a minimumbody-to-antenna distance of 20 cm (8 in.) must be maintained when the bridge is operational.

WARNING: To avoid possible injury or damage to equipment, you must use power supply equipment that is safety certified according to UL, CSA, IEC, or other applicable national or international safety requirements for the country of use. All references to power supply in this document refer to equipment meeting these requirements.
