AP2750 Managed Access Point

3CRWX275075A

The 3Com AP2750 Managed Access Point provides IEEE 802.11a or 802.11b/g wireless access to the
network. The access point is designed for use with a 3Com Wireless LAN Switch, and requires
hardware installation only. All configuration for the access point takes place on the 3Com Wireless
LAN Switch.

You must have a wireless switch device to operate the access point. Two WLAN switch devices can be
connected to the access point:

• 3Com WX4400

• 3Com WX1200

Power can be supplied via Power Over Ethernet (PoE) or by an external power supply. Four 3Com PoE
devices supply power to the access point:

• 3Com PoE Injector

• 3Com 4400PWR PoE Switch

• 3Com Multi-port PoE power supply

• 3Com WX1200

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 access point.

WARNING: To comply with FCC radio frequency (RF) exposure limits, a minimum body-to-

antenna distance of 20 cm (8 in.) must be maintained when the access point 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.

1 Unpacking the Access Point

Make sure that you have the following items, which are included with the access point:

• Two external 2.4 GHz and 5.3 GHz dual-band antennas

• Mounting bracket (attached to the access point)

• Wall-mounting hardware:

• Locking bar (used for securing a wall- or ceiling-mounted installation)

• Two sheet metal screws

• Two thread screws

• Two wall anchors

• Four adhesive rubber feet (used for a flat-surface installation).

2 Preparing for Installation

It is advisable to connect the power (if using an external power supply) and check the Ethernet cables
and LEDs before installing the access

point in a hard-to-reach location. Additionally, observe the

following items before mounting or connecting the access point:
