Verifying the AP3915i Box Contents

Verify the contents of the box and ensure that the following items are

available:

Mounting and Connecting the AP

Use these instructions as guidelines for mounting and connecting the AP3915i

easily and safely.

The AP3915i comes with a Mounting Bracket (#37201) that can be used to

mount the AP on a flat t-bar with flat ceiling tiles, flat surfaces, beams, and

some junction/gang boxes. An adaptor and brackets are available for

mounting the AP to non-flat ceiling tiles and t-bars. To mount the AP3915i on a

junction/gang box, use the optional bracket (WS-MBI-WALL04; #30516). All

additional and optional parts are sold separately.

Mounting the AP to a Suspended or Drop Ceiling

The AP3915i can be mounted to a suspended or drop ceiling directly using the

mounting bracket on the t-bar. If there is a ceiling tile protrusion, add the

optional T-bar adaptor to the main mounting bracket prior to T-bar

installation.

Option 1: Using the Main Mounting Bracket to a Flat T-bar

Before installation ensure that:

• The minimum base thickness of the T-bar that supports the ceiling tile is

0.031”.

• The maximum base thickness of the T-bar of the T-bar is 0.055”.

1 Remove the ceiling tiles, push and rotate the main mounting bracket onto

the T-bar in such a way that the center angled locking tabs of the main

bracket gets attached to the T-bar (Figure 3).

2 Replace the tiles to hold the T-bar in place.

3 Hold the AP and rock it back and forth to ensure it is securely mounted.

4 Attach the Ethernet cable’s RJ45 connector to the LAN1/GE1 port.

Option 2: Mounting the AP by attaching an adaptor to the main bracket

1 Attach the T-bar adaptor by lining up the small bends on the adaptor with

the long raised parts on the main bracket, pull up on the adaptor’s locking

AP assembled onto the AP

1 Cloud Quick Start Card

The following hardware is included:

2 Phillips Pan-head wood screws

2 Screw-in anchors

Electrical Hazard: Only qualified personnel should perform

installation procedures.

Note: The mounting procedures for installing the AP using the WS-

MBI-DCFLUSH (ordering part #37211) adaptor to a T-bar, WS-MBI-

DCMTR01 (ordering part #30518) to a T-bar, and using the main

mounting bracket (ordering part #37201) along with a flat metal-easy

attach adaptor (ordering part #37210) are covered in the

ExtremeWireless AP3915i Installation Guide.

Note: The T-bar width can be either 9/16” (15mm) or 15/16” (24mm).

Note: Mounting the AP to a suspended or drop ceiling requires the

optional adapter (Universal Mounting Kit for WLAN APs; # KT-

135628-01). The adaptor requires a flat t-bar and fits a ceiling tile with

up to a 0.35” protrusion from the bar.

pin, and twist. Make sure the locking pin goes into the locking pin hole on

the main bracket and locks in place.

2 Slide the T-bar holder onto the T-bar and replace the tiles to hold the

adaptor onto the T-bar.

3 Hold the AP and rock it back and forth to ensure that it is securely

mounted.

4 Attach the Ethernet cable’s RJ45 connector to the LAN1/GE1 port.

The optional WS-MBI-DCMTR01 (#30518) adaptor can also be used for T-bar

installations without the mounting bracket.

For detailed instructions, see the ExtremeWireless AP3915i Installation Guide.

Mounting the AP on a Dry or Wood Wall/Solid Flat

Ceiling

Pre-installation checklist:

• The mounting surface, item, and hardware must be able to support the AP

in all environmental conditions.

• The mounting surface should be flat.

To install the AP on a dry wall or flat surface:

Option 1: Using the Main Mounting Bracket

1 Remove the mounting bracket attached to the back of the AP.

2 Use the mounting bracket as a template and mark the hole centers on the

wall (Figure 5).

Figure 5 AP3915i Mounting Bracket

3 Insert the screws into the holes of the mounting bracket and use the screw-

in anchors if needed.

4 Insert the Ethernet cable’s RJ45 connector into the LAN1/GE1 port.

5 Insert the AP onto the bracket’s four feet and slide it to the right to lock it in

place.

Option 2: Using an optional Wall and Box bracket

1 Install the WS-MBI-WALL04 bracket onto a wall/ceiling with two screws

and anchors if appropriate, and ensure that the locking tab is on the

bottom side.

Figure 6 Mounting the AP using the optional wall and box

bracket

Warning: The AP must be mounted ONLY horizontally if you mount

it onto a plenum space.

Note: The four feet of the bracket must be horizontal and pointing to

the left and the flat part of the bracket must be touching the surface it

is being attached to.

Note: Mounting the AP to a flat ceiling requires the WS-MBI-

WALL04 (#30516) bracket, two Philips Pan-head screws, and two

screw-in anchors.

• Use the optional wall and box bracket as a template and mark the holes to

be used. For wall mounting procedure, Extreme Networks recommends

using the “A” or “B” hole centers.

• Mark the hole centers to be used, on the attachment surface.

• Drill the holes and attach the bracket using the screws and anchors

provided in the kit.

2 Connect the LAN/Ethernet cable to the AP.

3 Insert the AP onto the keyhole posts and slide the AP and lock it into place

at about 1/4th inch.

Mounting the AP to a Bracket on a Junction or Gang

Box

To mount the AP to a Bracket on a Junction or Gang box:

1 Use the Wall and Box Bracket WS-MBI-WALL04 (#30516).

2 Remove the screws from the junction/gang box.

3 Line up the bracket holes on the junction/gang box and ensure that they

align. If the holes do not align, drill new holes.

4 Using the holes aligned together or the new ones drilled, attach the bracket

to the junction/gang box using the screws removed from the box earlier.

5 Connect the LAN/Ethernet cable to the AP.

6 Align the keyhole slots and posts and slide the AP onto the bracket until

you hear it lock in place.

Mounting the AP to a Beam (AP3915i)

Pre-installation checklist:

• The beam must be able to support the AP in all environmental conditions.

• The beam should be flat.

Before attaching the AP onto a beam, verify that:

• Beam attachment area is at least 0.5” (12.7mm) wide and as long as the

AP’s largest dimension.

• Beam mounting surface is less than 0.650” (16.5mm) thick.

To attach an AP to a beam, attach a beam clip (Accessory BRKT-000147A-01)

to the mounting bracket:

1 Attach the adapter to the mounting bracket by using a twisting motion.

2 Attach the mounting bracket to the AP.

3 Place the adapter on a beam in such a way that there is enough space

between the screw and clamp to be tightened.

4 Use the screw and clamp on the top of the adapter to secure the AP in

place on the beam.

5 Insert the Ethernet plug into the AP.

Figure 7 Attaching the beam clamp on a beam

Connecting a Power Supply to the AP3915i

If you need to power the AP3915i with an external 12V DC power supply, you

can plug the power cord into the power connector (callout 2 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 ExtremeWireless AP3915i Installation Guide for information about optional

power supplies.

Note: When using the A or B holes, if the holes are not near the

corners of the bracket, break off the corner to decrease bracket’s

visibility once the AP is installed.

Note: When you line up the holes, the locking tab on the bracket

must be pointing down and the junction/gang box must be fully

covered by the bracket. The bracket must be square to the rest of the

room walls and the two holes that are being used must be on the

opposite side of large center hole on the bracket.

Note: If the holes that you need to use are not near the corners of

the bracket, break off the corner to decrease bracket’s visibility once

the AP is installed.

Caution: Over tightening the screws will cause the bracket to bend.

If the bracket bends, you will not be able to slide the AP onto the

keyhole posts.
