Architectural Features
Console Port
The AP3935 i and e models both include a single RJ45 console port (shown in Figure 3: AP3935 Bottom
View on page 11) for debug purposes. This port enables connection of a console device to the AP
through a serial cable. The console device can be a PC or workstation running a VT-100 terminal
adapter emulator, or a VT-100 terminal.
LAN Port
The AP3935 has two 10/100/1000BaseT RJ45 LAN ports (see Figure 3: AP3935 Bottom View on page
11) that can be attached directly to a 10/100/1000BaseT LAN segment. This segment must conform to
the IEEE 802.3 or 802.3u specifications.
The APs appear as Ethernet nodes and perform a bridging function by moving packets from the wired
LAN to remote workstations on the wireless infrastructure.
The LAN ports also support power over Ethernet PoE 802.3at for full performance; (802.3af for low
performance mode). Refer to Installation on page 14, for information on supplying power to the AP
network port from a network device, such as a switch, that provides Power over Ethernet (PoE).

These procedures describe how to attach the AP3935 to a drop ceiling (flat or protruded), and how to
mount the AP to a wall.
Mounting the AP3935 to a Drop Ceiling
To mount the AP to a drop ceiling, use the mounting bracket that is provided with the AP.
1 Slide the ceiling mount bracket base into the metal base. The locking tab fits into the groove in the
fins.
Figure 6: Attaching Mount Bracket to the Access Point
2 Remove the ceiling panels around the drop ceiling T-bar rail and verify that the Ethernet cable can
reach the AP at the mounting point.
Installation
ExtremeWireless™ AP3935i & AP3935e Installation Guide 15

3 Slightly lift the movable T-bar locking tab to increase the space between the stationary and the
movable T-bar sides of the bracket. Then hook the stationary end of the T-bar bracket onto the T-
bar, as shown in Figure 7: Attaching the AP3935i on a Drop Ceiling T-bar Rail on page 16.
4 While holding the AP with one hand, reach the other hand over the T-bar and grasp both the
stationary and movable sides of the bracket. Push the bracket parts together so they both grasp the
T-bar and the locking tab clicks into place.
5 While still holding the AP, rock it back and forth to ensure that it is securely mounted.
Figure 7: Attaching the AP3935i on a Drop Ceiling T-bar Rail
6 Make a hole through the ceiling panel closest to the power slot on the AP. Run the Ethernet cable
through the hole and into an RJ45 LAN port in the recessed connector bay.
7 If necessary, cut the tiles for the cables, attach the cables to the AP, and replace the tiles.
8 Replace the displaced ceiling panels.
Mounting the AP3935 to a Wall
Screws for attaching the AP to a wall are supplied with the product. Use the following procedure to
mount the AP3935 to a flat wall:
Installation
ExtremeWireless™ AP3935i & AP3935e Installation Guide 16

1 Determine the spot on the wall to mount the AP. Pick a spot near the ceiling, but in reach of the
Ethernet cable and if you are using external power, near a wall power outlet.
2 To mount the AP directly on the wall with two screws, use the provided template and mark the two
drill holes on the wall. In drywall, the drill holes should be 6mm in diameter.
3 Drill two holes in the wall to match the center of the two keyhole slots in the back of the AP bracket.
4 Screw the anchors into the holes until they are flush with the wall.
5 Screw the provided mounting screws into the anchors with the head protruding about 5/32” from
the anchor to the top of the screw.
Figure 8: Mounting the AP3935 to a Flat Wall
6 Place the back of the AP against the wall with the protruding mounting screw heads fitting through
the keyhole slots on the back of the AP. Slide the AP down until the AP rests on the mounting screw
heads.
Installation
ExtremeWireless™ AP3935i & AP3935e Installation Guide 17

7 When mounting the AP on a wall or flat ceiling, a Kensington lock provides extra stability.
Note
The mounting bracket (30513, WS-MBI-WALL03) is optional when mounting the AP on a
wall. If mounting the AP on a flat ceiling, we recommend using the mounting bracket
(30513, WS-MBI-WALL03) for added security.
Mounting the AP using the Optional Mounting Bracket
When mounting the AP to a flat ceiling (or a wall), use the mounting bracket (30513, WS-MBI-WALL03)
and two metal screws. Figure 9: Mounting sequence with mounting bracket on page 18 shows an
exploded view of the mounting bracket method:
1 The wall bracket provides four attachment holes. Using the bracket as a template, place the bracket
and mark the drill holes.
2 Hold the AP/bracket assembly so the drilled holes are in the center of the bracket holes.
3 Insert and thread the screws so they support the bracket.
Figure 9: Mounting sequence with mounting bracket
4 Align the AP on the posts and slide down.
5 Use a screw driver to attach the captive screw. Do NOT exceed 9 in-lbs of torque.
6 Use a Kensington lock for added security (see Figure 5: Kensington Lock slot on page 13). The
Kensington lock, or an equivalent, must be used for all ceiling mounted applications of AP3935 with
WS-MBI-WALL03.
LAN/Console Connections
Note
LAN/Console connectors with shrouds will not fit into the ports. An optional jumper cable
may be used or the shroud removed.
The AP3935 has 2 LAN ports and a Console port. Power is provided through two Ethernet ports (LAN
ports). This is the preferred method of powering the AP on ceiling and wall installations.
The AP can be powered in one of the following ways:
•Power over Ethernet (PoE)
Installation
ExtremeWireless™ AP3935i & AP3935e Installation Guide 18

Power is provided through the RJ45 Ethernet port (LAN port) on the top of the AP. This is the
preferred method of powering the AP on ceiling and high wall installations.
•Power by external power supply
Where a PoE-capable Ethernet connection is unavailable or impractical, an external 12 VDC power
supply may be ordered separately to power the AP from a standard AC wall outlet.
Figure 10: 3935e Access Point Bottom View
1Reset Button 3LAN Ethernet Ports 1 and 2
2Console Port 4External Power 12 VDC
Connecting an External DC Power Supply to the AP3935
There are no wall mounts for the 12 VDC power supplies. To connect a power supply to the AP for
everyday operation, mount the AP and plug the power supply into the DC-IN port (Figure 10: 3935e
Access Point Bottom View on page 19). If you have taken the AP o its mount for configuration and
maintenance, the AP still needs power during the maintenance. Provide power from a DC power supply
or PoE LAN connector.
Configuring AP3935e Channel Settings
The AP3935e must be installed by a professional installer. Before starting the installation, the installer
needs to determine and configure the following:
Installation
