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:

Installation Item Description

Switch port 3Com recommends that you install and configure the 3Com Wireless LAN switch

Cabling Make sure that standard Category 5 cable with straight-through signaling is

Power Requirements Power can be supplied via an 802.3af Power Over Ethernet (PoE)-compliant device

installed at the site before you install the access point. 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.

installed in a hard-to-reach location. The MAC address is printed on the back of the access point. Additional MAC

address labels are shipped with the access point.

3 Attaching the Antennas

Carefully unpack the standard detachable antennas. Screw the antennas on to the antenna connectors on the access point 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 access point. This could lead to electrostatic discharge (ESD), which could damage the equipment.

4 Mounting the Access Point

The access point can be mounted on the following types of surfaces:

• Wall, ceiling, or electrical box (NEMA enclosure)

•Tabletop

CAUTION: The access point is intended for indoor use only. Do not install the access point outdoors unless you install it in a properly installed outdoor access point enclosure.

Wall, Ceiling, or Electrical Box Mounting

To mount the access point to a wall, ceiling, or electrical box:

1 Remove the access point from the mounting bracket. 2 Screw the mounting bracket to a wall, ceiling, or electrical box (NEMA enclosure):

• If mounting to a solid surface wall or ceiling, use the two sheet metal screws.

• If mounting to drywall, use the two sheet metal screws and two wall anchors.

• If mounting to an electrical box (NEMA enclosure), use the two threaded screws.

3 Route the power cable (if using an external power supply) and Ethernet cable

through the large opening on the back of the mounting bracket.

CAUTION: For easy installation and removal of the access point from the mounting bracket, make sure that there is sufficient flexibility with the cable and that there is adequate service loop (that is, enough cable routed through the mounting bracket to easily connect the cable to the access point.) If not enough cable is routed through the back of the mounting bracket, or if the cable is inflexible, it can be difficult to install or remove the access point from the mounting bracket.

The figures below show the mounting bracket being mounted to a wall, and then a cable being routed through the large opening on the back of the mounting bracket.

4 Connect the Ethernet cable (and power cable, if applicable) to the port(s) on the

front of the access point.

5 Snap the access point onto the mounting bracket.

To install the locking bar, push the locking bar through the opening in the side of the mounting bracket until the hole on the locking bar is exposed. Insert a lock (not provided) through the hole on the locking bar, and then close the lock to secure it in place.
