installation CD.)

2 Prepare for Installation

It is advisable to connect the power and check the Ethernet cables and LEDs before installing the unit in

a hard-to-reach location.

Observe the following power requirements:

The access point complies with the IEEE 802.3af power-over-Ethernet standard. It receives

power over category 5 straight cable. Installation requires the use of either the 3Com power

supply provided or IEEE 802.3af compliant power supply equipment (output power rated

48 V DC @ 350 mA maximum). Such equipment must be safety certiﬁed according to UL,

CSA, IEC or other applicable national or international safety requirements for the country of

use. All references to the power supply refer to equipment that meets these requirements.

Because the power supply plug is the only means of disconnecting the access point from

power, make sure the power outlet is accessible.

The power supply can be located indoors at any point between the access point and the LAN

access port where an accessible power outlet exists.

Decide where to place the access point.

■

Mounted on a wall on a stud (or other hard surface)

■

Mounted on to drywall

■

Placed on a ﬂat surface

The location should be elevated and centrally located relative to users on your network. Ceiling

mounting is not recommended.

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 housing.

Access Point 8200 or Access Point 8700: Carefully unpack the standard detachable

antennas. Screw the antennas on to the SMA connectors and hand-tighten them.

After network startup, you may need to adjust the antennas to ﬁne-tune coverage

in your area.

NOTE:

Regulatory restrictions dictate that when the access point is operational a minimum

body-to-antenna distance of 1 meter (3 feet) must be maintained.

The

installation CD includes the User Guide, which contains more detailed information on planning,

installing and conﬁguring the device. Additional tools and utilities are provided to assist with the

management of your network. See “Documentation and Software Utilities” on page 7 for instructions.

3 Connect the Power

The access point complies with the IEEE 802.3af power-over-Ethernet standard. It receives power over a

standard category 5 straight (8-wire) Ethernet cable. There are two ways to supply power to the access

point (refer to the illustration below):

■

Use the supplied 3Com Integrated Power-over-Ethernet power supply.

In this case,

you need to supply a second Ethernet cable to connect to the wired LAN.

■

Connect the access point directly to your own power-over-Ethernet hub or switch, which

must also comply with the IEEE 802.3af standard.

Using the Power Supply

The power supply can be located at any point between the access point and the LAN access port,

wherever a convenient power outlet exists. If you supply your own Ethernet cable for connecting power,

be sure that it is standard category 5 straight-through (8-wire) cable that has not been altered in any

way. Use of nonstandard cable could damage the access point.

Refer to the illustration above, and follow these steps:

Connect one end of the Ethernet cable to the Ethernet port on the access point.

Connect the other end of the Ethernet cable to the port labeled

To Access Point

the power supply.

Connect the power cord to the power supply and plug the cord into a power outlet.

CAUTION:

Do not handle the antenna tips, especially after they are connected to the access

point, as this could lead to electrostatic discharge (ESD), which could damage

the equipment.

To link the access point to your Ethernet network, plug one end of another Ethernet

cable into the port labeled To

Hub/Switch

on the power supply, and plug the other

end into a LAN port (on a hub or in a wall).

Using a Power-Over-Ethernet LAN Port

If your LAN equipment complies with the IEEE 802.3af power-over-Ethernet standard, you can connect

the access point directly to a LAN port. For example, the illustration above right shows a connection

through a 3Com Ethernet Power Supply to a 3Com SuperStack

Switch.

4 Check the LEDs

When power is connected, the access point LEDs light. The illustration and the following table describe

the LEDs and their functions.

CAUTION:

To avoid damaging network equipment, make sure that the cables are

connected from access point to power supply to LAN as shown and described above.

5 Wall Mount Installation

Install the mounting plate as shown in the following illustration, on either a stud

(or other hard wall surface), or onto drywall.

■

Allow for a clearance of at least 25 cm (10 Inches) between the ceiling and the top of the

mounting plate.

■

Make sure that “UP” is correctly oriented, and align the mounting plate screw

holes vertically.

■

For installation on a wall stud, install the top screw into the stud, as shown at left in the

illustration, and then vertically align the mounting plate before installing the

bottom screw.

■

For installation on to drywall, mark three screw holes using the mounting plate as a

template for vertical alignment, as shown at right in the illustration above.

■

Use a 5-mm (3/16-in.) drill bit if using the plastic anchors provided.

■

For drywall mounts, you can route the cable through either a side or center opening for a

seamless appearance using one of the methods illustrated below. Alternatively, you can

simply attach the Ethernet cable to the side of the unit, allowing it to trail along the wall.

■

If you have routed the Ethernet cable through the center opening, secure the cable on the

hook located on the mounting plate as shown in the illustration below.

Connect the Ethernet cable to the Ethernet port on the access point.

Position the access point at an angle to the mounting plate bayonet connection and

turn the unit clockwise until it snaps into place, as shown below.

If installing into drywall, use

3 plastic anchors and 3 screws.
