1. Unpacking the Access Point

Make sure that you have the following items, which are included with the Access Point:

•One 3Com Wireless 7760 11a/b/g PoE Access Point

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

•One PoE (Power over Ethernet) injector

•One Ethernet cable

•Wall-mounting hardware:

•Mounting bracket (attached to the Access Point)

•One 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).

•One CD-ROM containing the Setup Wizard software, the User’s Manual, and a copy of this

Quick Start Guide.

•One Warranty Flyer

2. Preparing for Installation

It is advisable to connect and check the Ethernet cable 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:

Feature Description

Switch Port To connect your wireless network to your wired network, you need a

hub or switch connected to the Access Point.

Cabling Make sure that standard Ethernet cable with straight-through

signaling is 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.

Power Requirement Power is supplied using an 802.3af Power Over Ethernet (PoE)

compliant device. A PoE injector is included.

MAC Address Record the access point MAC address in a safe place before the

Access Point is 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 that came with your Access Point. Thread

each antenna on to an antenna connector 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 they are perpendicular to the floor and ceiling.

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

Wall, Ceiling, or Electrical Box Mounting

Use the mounting bracket that comes with your Access Point to install it on a wall, ceiling, or

electrical box. For additional security, use the included locking bar and a lock (not provided) to

lock the Access Point to the cradle after it is mounted to a wall.

To wall-mount the Access Point:

1Route Ethernet cable through the large opening in the cradle.

2Screw 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.

The figures below show a cable being routed through the large opening in the cradle and

then the cradle being mounted to a wall.

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.

Wall-mounting the cradleRouting a cable

3Connect the Ethernet cable (for power and network connection) to the port on the front of

the Access Point.

4Snap the Access Point onto the mounting bracket.

5To 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.

Tabletop Mounting

To install the Access Point on a flat surface such as a table or desktop:

1Remove the backing from the four rubber feet and attach them on the bottom of the

mounting bracket that is attached to the Access Point.

2Place the Access Point on the table.

3Connect the Ethernet cable (for power and network connection) to the port on the front of

the Access Point.

5. Connecting Power

The Access Point can be powered by the following methods:

•By Power Over Ethernet (PoE) supplied over the LAN by a 802.3af PoE compliant device such

as a switch or hub.

•By PoE supplied by the PoE injector included with the Access Point.

Power Over Ethernet (PoE) from the LAN

To power the Access Point using PoE provided by a switch or other 802.3af compliant device,

simply plug the network cable from the device into the Access Point’s Ethernet port.

Power Over Ethernet from a PoE Injector

To power the Access Point using the 3Com PoE Injector (included with the unit), do the following:

1Connect the LAN cable from the switch or hub to the Hub/Switch port on the 3Com PoE

Injector (included with Access Point).

2Next connect a LAN cable from the Ethernet port on the Access Point to the other port on

the PoE injector.

3Plug the PoE Injector into a properly grounded electric outlet.
