Installing the Access Point
z
Relatively unobstructed access to the mobile stations that it will serve
z A power-over-Ethernet connection to the network switch servicing the controller
The access point communicates with mobile stations using radio waves like those
used by cordless phones. These radio waves can go through walls, floors, and
windows, but all of these reduce the range. Find a location where the radio waves can
get to the mobile station with as little obstruction as possible. In an office with cubicles, mounting the access points on the ceiling or on the wall near the ceiling might
allow the radio waves to avoid furniture and cubicle walls.
The location must also have a 100BaseT power-over-Ethernet (PoE) connection from
the access point to the switch for the controller. The power can be supplied by a PoE
switch or by a PoE power injector between the switch and the access point.
Attaching the Antennas
Mounting the Access Point
Attach the antennas to the connectors on the access point and hand tighten.
Horizontal Mounting
1. Place the access point flat on the horizontal surface.
2. Point the antennas up.
3. Connect the PoE 100BaseT Ethernet cable.
Vertical Mounting
1. Mark the location for the two access point mounting screws. They must be 4 ½
inches apart, center-to-center, one above the other. If you are not using plastic wall
anchors, you must center the mounting screws on a wall stud. If you do not center
the mounting screws on a wall stud, you must use plastic wall anchors.
2. Drill holes at the locations you marked:
— 3/16-inch holes if you are using plastic anchors
— 1/8-inch holes if you are using only the screws
3. If you are using plastic anchors, install them in the holes.
4. Screw in the screws most of the way, so that the screw head is about 1/16 of an
inch from the wall.
5. Mount the access point on the screws, placing the circular portion of the keyhole
mounts over the screw heads and sliding the access point down.
6. Point the antennas up.
7. Connect the PoE 100BaseT Ethernet cable.
Mounting Below a Ceiling
1. Mark the location of the two mounting screws. They must be 4 ½ inches apart,
center-to-center.
2. Drill holes at the locations you marked:

Mounting Above a Ceiling Tile
1. Remove the ceiling tile where the access point will be located.
2. Confirm that there is at least 6 inches of space above the ceiling tile to accommo-

for at least three inches to the side and three inches above the access point.
extender. The hole should be at least 6 inches from the edge of the tile.
4. Insert the light-pipe extender into the hole, with the 2-inch flange on the appear-
ance side of the ceiling tile.
5. Attach the mounting bracket to the light-pipe extender, with the two small pins
on the light-pipe extender fitting into the small holes on the mounting bracket and
the two hooked tabs fitting into the two notches in the mounting bracket hole.
Note that the tabs are different widths and the wide tab fits only into the wide
notch. Press the tabs in towards each other to clear the edges of the notch. They
will lock in place.
6. Attach the mounting bracket to the ceiling tile, using two #6 screws.

8. Position the small holes on the bracket over the small holes on the back of the
access point. Use two screws supplied to attach the bracket to the access point.
9. Point the antennas up.
10.Return the ceiling tile to the ceiling, but leave the tile loose.
11. Connect the PoE 100BaseT Ethernet cable to the access point.
12.Reposition the antennas, if needed.
13.Replace the ceiling tile in the ceiling brackets.

LED Activity
LED Activity
After the Air Point 100 access point is connected, the LEDs near the RJ-45 connector
should light.
Figure 3: RJ-45 LEDs
The green LED on the left indicates that Ethernet activity is taking place. The LED on
the right indicates that an Ethernet link is present. If this LED is yellow, the link is a
100BaseT link. If this LED is green, the link is a 10BaseT link.
The some of four LEDs on the face of the access point will also light. The LED closest
to the Meru logo and furthest from the Ethernet port lights green to indicate the presence of power. The other LEDs are explained in the System Administrator’s Guide.
Link present: yellow = 100MB; green = 10MB

Safety Precautions
Safety Precautions
Inside antennas must be positioned to observe minimum
separation of 20 cm. (~ 8 in.) from all users and bystanders. For
the protection of personnel working in the v icin ity of ins i de
(downlink) antennas, the following guidelines for minimum
distances between the human body and the antenna must be
observed.
WARNING!
WARNING!
The installation of an INDOOR antenna must be such that, under
normal conditions, all personnel cannot come within 20 cm. (~ 8.0
in.) from any inside antenna. Exceeding this minimum separation
will ensure that the employee or bystander does not receive RFexposure beyond the Maximum Permissible Exposure according
to section 1.1310 i.e. limits for General Population/Uncontrolled
Exposure.
The Outside antenna must be positioned to observe minimum
separation of 120 cm. (~ 4 ft.) from all users and bystanders. For
the protection of personnel working in the v icin ity of ou tside
(uplink) antennas, the following guidelines for minimum dist ances
between the human body and the antenna must be observed.
The installation of an OUTDOOR antenna must be such that,
under normal conditions, all personnel cannot come within 120
cm. (~ 4 ft.) from the outside antenna. In all installations, the
antenna should never be mounted such that the main beam is
directed toward an area where workers or bystanders may be
present. Exceeding this minimum separation will ensure that the
worker or bystander does not receive RF-exposure beyond the
Maximum Permissible Exposure according to section 1.1310 i.e.
limits for General Population/Uncontrolled Exposure.
