Overview of the WS-AP3825
The WS-AP3825 is designed to extend your Wireless LAN
around indoor locations. The WS-AP3825 supports the
802.11ac and 802.11n wireless standards, with full backward
compatibility with legacy 802.11a, 802.11b, and 802.11g
devices. The WS-AP3825 interoperates fully with Wireless
LANs, including support for VoWLAN, branch office mode,
guest services, RTLS, availability, and mobility features.
WS-AP3825 models have the following features:
• Radios: 2 radios (2.4 GHz and 5 GHz)
• LEDs: 5 (see
Figure 2
)
• Power: PoE 802.3af; DC power supply (see
Table 1
)
• Antennas:
– WS-AP3825i: 6
internal
single band antenna
assemblies
– WS-AP3825e: 6
external
RSMA antenna connectors
(external antennas must be ordered separately)
• Mounting brackets for 15/16” drop ceiling T-bar rail:
– 1 protruded drop ceiling rail bracket
– 1 flat drop ceiling rail bracket

, the figure on the left shows a front view of the
WS-AP3825i. The figure on the right shows a front view of
the WS-AP3825e.

Note:
The WS-AP3825 is available in both an “i” model
(with internal antennas) and an “e” model (with external
antennas). In this Quick Reference, any reference to
WS-AP3825
applies to both models.

Mounting and Connecting the AP
Mounting brackets are included for quick and easy
mounting of the WS-AP3825 to walls and drop ceilings. Use
these instructions as guidelines for mounting and
connecting the WS-AP3825 easily and safely.
Mounting on a Drop Ceiling
1 Attach the T-bar rail mount bracket to the back of the
AP. Place the bracket against the AP back, aligned as
shown in
Figure 3
, with screw holes matched up. Screw
the provided screws (M3) through the bracket into the
AP back as shown in
Figure 3
.

Power
Source
Description
Power over
Ethernet
(PoE)
Power is provided through the RJ45 Ethernet port
(LAN port) on the top of the WS-AP3825. This is the
preferred method of powering the AP on ceiling and
high wall installations.
External 12V
DC power
supply
(optional)
The WS-AP3825 can also be powered by an external
DC power supply plugged into an AC source. Plug
the supply’s input jack into the DC-In port (callout 3
in
Figure 1
).

Attaching Mount Bracket to AP
2 Remove the ceiling panels around the drop ceiling T-bar
rails where you intend to mount the AP. Verify that the
Ethernet cable that will connect to the AP can reach the
AP at the point where you plan to mount it.
3 Hold the AP nearly parallel to the T-bar rail with the
bracket against the flat side of the T-bar rail. The
clamping tabs fit over the rail easily if you slide one
bracket tab over the lip of the rail, at a very slight angle
to the rail, and then twist the AP so that the opposite
bracket tab slides over the opposite rail lip. There are flex
tabs immediately opposite each bracket tab, to stabilize
the bracket against the rail during the twisting motion.
4 With both bracket tabs over the T-bar rail lips, tap the AP
to verify it is stable and won’t fall off.

the AP and bracket mounted on a T-bar rail.

5 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.
6 Replace the displaced ceiling panels.
Mounting on a Wall/Solid Flat Ceiling
1 Determine the spot on the wall where the AP is to be
mounted, preferably high up on the wall (near the ceiling
for maximum radio wave dispersion) but in reach of the
Ethernet cable and a wall power outlet if you are not able
to use Power over Ethernet.
2 Drill two holes in the wall to match the center of the two
keyhole slots in the back of the AP. For a tight fit, the
holes should be slightly smaller than the diameter of the
provided plastic anchors.
3 Tap the plastic anchors into the holes with a hammer
until they are flush with the wall, and screw the provided
mounting screws into the anchors, with the head
protruding 1/16” from the anchor.
4 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, and slide the AP
down until the AP rests on the mounting screw heads.
Figure 5
shows an exploded view of this mounting
method.

Connecting a Power Supply to the WS-AP3825
If you need to power the WS-AP3825 with an external 12V
DC power supply, you can plug the power cord into the
power connector (callout 3 in
Figure 1
) on the back of the
AP. There is no wall mount for the 12V DC power supply.
When the device is powered on, the power LED on the front
face of the AP is lit. Refer to the
Extreme Networks Wireless
AP3825 Installation Guide
for information about optional
power supplies.
LAN/Console Connections
The WS-AP3825 has two LAN (Ethernet) ports and a
Console port. Refer to
Figure 1
for the location of these
ports. During administration and maintenance through the
LAN or Console, the AP must still have a power connection
through either an Ethernet PoE cable or a DC power supply.
External Antennas (WS-AP3825e Only)
Install the external antennas intended for area coverage.
For information about antenna selection and installation,
refer to the
Extreme Networks Wireless AP3825 Installation
Guide
.
Note:
LAN/Console connectors with shrouds will not fit into
the ports. Remove the shroud or use an optional jumper
cable.
