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 GHz dual-band antennas
•Mounting bracket (attached to the access point)
•Wall-mounting hardware:
•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 before installing the access point. Set the port type on the
switch to an AP3150 access point.
Cabling Make sure that standard Category 5 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 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 access point from power.
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. 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.
Connecting Optional External Antennas
The access point has connectors for attaching optional external antennas and antenna cables. The
tables below list the external antenna and cable models that are certified for use with the access
point.
The 3Com antennas are dual-band, which means that they operate in both 2.4 GHz and 5 GHz
spectra. You can use these antennas with either the 802.11b/g radio or the 802.11a radio. Each
antenna requires the purchase of a separate antenna cable. For installation instructions, see the
documentation that is supplied with the antenna.
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.

3CWE586 3Com RSMA to SMA 6-inch Antenna Cable
Note 3CWE586 is required when using any of the external antennas
NOTE: Antenna cables introduce loss of the RF signal. Always use the shortest cable that
your application allows.
NOTE: During the installation, connect the antenna to the access point before connecting
the Category 5 Ethernet cable. This ensures that the access point is not powered on when
the antenna connections are made.

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.
To wall-mount the access point:
1Route Ethernet cable through the 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.
3Connect the Ethernet cable (for power and network connection) to the port on the rear of
the access point.
4Twist the access point onto the mounting bracket.
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 access
point.
2Place the access point on the table.
3Connect the Ethernet cable (for power and network connection) to the port on the rear of
the access point.

5. Connecting the Access Point to a Switch
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 an optional 3Com PoE injector (not included). 3Com PoE injectors include
the 3CNJPSE and 3CNJPSE24 midspan supplies.
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 a 3Com PoE Injector (available separately), do the following:
1Connect the LAN cable from the switch or hub to the Hub/Switch port on the 3Com PoE
Injector (available separately).
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.
