About the WS-AP3825i and WS-AP3825e
The WS-AP3825i and WS-AP3825e access points are a cost-eective solution for extending your
wireless LAN around indoor locations. They interoperate fully with the Extreme Networks wireless LAN,
including support for Extreme Networks wireless VoWLAN, branch oce mode, availability, and
mobility features.
The WS-AP3825i and WS-AP3825e are nearly identical in appearance and have the following features in
common:
•Both operate in 802.11ac and 802.11n mode and also support 802.11a/802.11g and 802.11b standard
legacy devices.
•Both support two MIMO 3x3 (up to three 802.11ac spatial streams).
•They provide two single-band radios for dual-band, concurrent operation, optimized for indoor
antenna coverage:
•5 GHz (Radio 1) in any of the following modes: IEEE802.11ac, a/b/g and/or n
•2.4 GHz (Radio 2) in any of the following modes: IEEE802.11ac, a/b/g and/or n
•They are enclosed in a rectangular, compact case.
•Both models include two mounting brackets, and screws/anchors, for mounting them to walls and
drop/suspended ceilings.
•They provide 40MHz Bandwidth at 2.4/5 GHz operation (Channel Bonding).
•They can be powered directly through the LAN using Power over Ethernet (PoE), or by an external
110/240V AC/DC adaptor.
•Both have dual Ethernet (LAN) ports for fault-tolerant network connection and failover.
Note
The WS-AP3825 comes in two models: the WS-AP3825i has six internal single-band antennas
while the WS-AP3825e has six external RSMA connectors for connecting external antennas.
Within this document, any reference to WSAP3825 applies to both models.
WS-AP3825 Overview
The WS-AP3825 access point is available in two models:
•WS-AP3825i contains six internal single-band antennas
•WS-AP3825e contains six external RSMA connectors for optional external antennas, for greater
range and coverage versatility

Architectural Features
Console Port
The WS-AP3825 i and e models both include a single RJ45 console port (shown in Figure 1 on page 8
and Figure 2 on page 9) 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 WS-AP3825 has two 10/100/1000BaseT RJ45 LAN ports (see Figure 1 on page 8) 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) based on the IEEE 802.3af standard. 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).
Reset Switch
The WS-AP3825 provides a Reset Switch to reset or restore factory default configurations. Use a pen tip
or a nail to press the switch button through the hole (located on the top side of the AP). If you hold
down the button for less than 5 seconds, the AP performs a software interrupt, causing it to drop all
connections and reset. If you hold the button down for 5 seconds or more, any configuration changes
are removed, and the factory default configuration restores to the AP.

These procedures describe how to attach the WS-AP3825 to a drop ceiling (flat or protruded), and how
to mount the AP to a wall.
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 14

Mounting the WS-AP3825 to a Drop Ceiling
To mount the AP to a drop ceiling, use one of the mounting brackets provided with the AP. There are
brackets for flat drop ceilings and protruded drop ceilings.
•Flat Drop Ceiling Bracket
Flat drop ceilings are those in which the ceiling tiles rest flat (or nearly so) on their supporting T-bar
rails. The flat drop ceiling bracket has a low flat profile, to mount the AP close against the T-bar rail.
•Protruded Drop Ceiling Bracket
Protruded drop ceilings are those in which the ceiling tiles protrude well beyond the T-bar rails on
which they rest. The protruded drop ceiling bracket has an extended mount plate, allowing the AP to
hang below the protruded ceiling tiles.
Note
We recommend that the first time you mount an AP3825 to a drop ceiling T-bar rail, you try
mounting the bracket to a rail before attaching it to the back of an AP and mounting the AP
to the rail. This way you can get the “feel” of the tilt and twist motion described in step 3on
page 17 in the procedure below, to make the bracket tabs clear the rail and slide over the rail
lip on both sides.
To attach the WS-AP3825 to a drop ceiling:
Installation
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 15

1 Attach the T-bar rail mount bracket to the back of the AP by placing the bracket against the AP
back, aligned as shown in Figure 5, with the bracket’s countersink screw holes matched up with the
screw holes on the AP. Screw the provided screws into the mounting bracket and AP as shown in
Figure 5.
Figure 5: Attaching a Mount Bracket to the AP back
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.
Installation
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 16

3 Hold the AP with the bracket against the flat side of the T-bar rail and (nearly) parallel to it. 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 press the AP up against the rail (so that the opposite clamping tab clears
the rail) and twist it so that the opposite clamping tab slides over the opposite rail lip as shown in
Figure 6. There are flex tabs immediately opposite each bracket tab, that flex out (away from the
rail) to stabilize the bracket against the rail while you pivot the AP and bracket to clear the rail.
Figure 6: Mounting the Bracket to the Ceiling Rail
Installation
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 17

4 When the bracket is aligned with the rail again, both clamping tabs are positioned on the T-bar rail
lips. Figure 7 shows a mounting bracket, with an AP attached, firmly mounted on a drop-ceiling T-
bar rail. Tap the AP to verify it is stable and won't fall o.
Figure 7: AP and Mounting Bracket Seated on T-bar Rail
5 Make a hole through the ceiling panel closest to the connector bay on the AP. Then run the Ethernet
cable through the hole and into a LAN port (RJ45 Ethernet port) in the connector bay.
6 Replace the displaced ceiling panels.
Mounting the WS-AP3825 to a Wall or Solid Ceiling
Screws for attaching the AP to a wall or solid ceiling are supplied with the product. Use the following
procedure to mount the AP3825 to a flat wall.
1 Determine the spot 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.
Installation
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 18

2 Drill two holes in the wall to match the center of the two keyhole slots in the back of the AP. The
location of the holes is depicted in Figure 8 (measurements are in millimeters). For a tight fit, the
holes should be slightly smaller than the diameter of the provided plastic anchors.
Figure 8: Drilling Template for Wall Mounting
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.
Installation
ExtremeWireless™ WS-AP3825i & WS-AP3825e Installation Guide for version . 19

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 9 shows an exploded view of this mounting method.
Figure 9: Mounting the WS-AP3825 to a Flat Wall or Solid Ceiling
5 Plug the Ethernet cable into the RJ-45 port (and plug the power cord into the power port, if
applicable) on the back of the AP.
WS-MBI-DCU01 Mounting Bracket for Drop Ceiling
The optional WS-MBI-DCU01 mounting bracket fits 9/16", 14MM, 15/16", 24MM, 1.5", and 38MM wide drop
ceiling rails. This bracket uses four M3 flat head screws to attach it to the AP3825.
