3Com WL-548A manual Unpacking the Sensor, Preparing for Installation, Attaching the Antennas

1. Unpacking the Sensor

Make sure that you have the following items, which are included in the package:

•One 3Com AirProtect Sensor 5750

•Two external 2.4 GHz and 5 GHz dual- band antennas

•Rear panel cover

•Mounting bracket

•Wall-mounting hardware

•Four adhesive rubber feet

(used for a flat-surface installation)

•Category 5 Ethernet cable

•This Quick Installation Guide

•Warranty flyers (English and Spanish)

•Regulatory sticker sheet

2. Preparing for Installation

It is advisable to connect the power (if using an external PoE supply) and check the Ethernet cables and LEDs before installing the sensor in a hard-to-reach location. Additionally, observe the following items before mounting or connecting the sensor:

Installation Item	Description
Switch port	The sensor must connected to the same wired network as the
	AirProtect Engine 6100. 3Com recommends that you install and
	configure the 3Com AirProtect Engine 6100 before installing the
	sensor.
Cabling	Make sure that standard Category 5 cable with straight-through
	signaling is installed at the site before you install the sensor.
	Make sure that the cable is highly flexible and that there is no extra
	covering on the RJ-45 connector that could prevent the cable from
	being routed through the mounting bracket.
Power Requirements	Power must be supplied from an 802.3af Power Over Ethernet (PoE)-
	compliant device.
	If using an external PoE power injector, make sure the power outlet is
	accessible. The power supply plug is the only means of disconnecting
	the sensor from power.
MAC Address	Record the sensor MAC address in a safe place before the sensor is
	installed in a hard-to-reach location. The MAC address is printed on
	the back of the sensor.

3. Attaching the Antennas

Carefully unpack the standard detachable antennas. Screw the antennas on to the antenna connectors on the sensor and hand-tighten them. After network startup, you may need to adjust the antennas to fine-tune coverage in your area. For best results, adjust the antennas so that they are perpendicular with the floor and ceiling.

CAUTION: Do not handle the antenna tips, especially after they are connected to the sensor. This could lead to electrostatic discharge (ESD), which could damage the equipment.
