Mount the AP21 Access Point

This topic provides the various mounting options for the AP21. You can mount the AP on a wall, ceiling or junction box. The AP ships with a universal mounting bracket that you can use for all mounting options. To mount the AP on a ceiling, you'll need to order an additional adapter based on the type of ceiling.

Note:

We recommend that you claim your AP before you mount it. The claim code is located on the rear of the AP and it might be difficult to access the claim code after you mount the AP. For information about claiming an AP, see Claim a Juniper Access Point.

Universal Mounting Bracket (APBR-U) for Juniper Access Points

You use the universal mounting bracket APBR-U for all types of mounting options—for example, on a wall, a ceiling, or a junction box. Figure 1 shows the APBR-U. You'll need to use the numbered holes to insert screws when mounting the AP on a junction box. The numbered holes that you use vary based on the type of junction box.

Figure 1: Universal Mounting Bracket (APBR-U) for Juniper Access Points Technical drawing of a mechanical component with numbered labels, showing cutouts, slots, and mounting points.

If you're mounting the AP on a wall, use screws with the following specifications:

  • Diameter of the screw head: ¼ in. (6.3 mm)

  • Length: At least 2 in. (50.8 mm)

The following table lists the bracket holes that you need to use for specific mounting options.

Hole Number Mounting Option
1

  • US single-gang junction box

  • 3.5 in. round junction box

  • 4 in. round junction box
2

  • US double-gang junction box

  • Wall

  • Ceiling
3

  • US 4-in. square junction box

  • EU junction box

This is the new Mist BR-U bracket that works for all our indoor APs. We'll ship with the shoulder screws already installed, so attached to the BR-U bracket as follows. You will note a strong click when the locking lever engages. To remove, you need to gently push the lever out of the way and slide the AP back out.

Mount an Access Point on a Single-Gang or 3.5-Inch or 4-Inch Round Junction Box

You can mount an access point (AP) on a US single-gang or a 3.5-in. or 4-in. round junction box by using the universal mounting bracket (APBR-U) that we ship along with the AP. To mount an AP on a single-gang junction box:
  1. Attach the mounting bracket to the single-gang junction box by using two screws. Ensure that you insert the screws in the holes marked 1 as shown in Figure 2.

    Figure 12: Attach the AP to a 9/16-in. or 15/16-in. T-Bar Diagram showing device mounting process; left view indicates upward attachment on bracket, right view shows downward securing motion.

You can directly connect to 9/16ths or 15/16ths T-bar by using these flanges and inserting the bracket as shown. You will hear a click when properly installed. To disconnect, please press the clips as shown and remove the AP. The AP would then be hung as shown. Again, to remove the AP, you must gently press the security lever while you slide it out.

Mount an Access Point on a Recessed 15/16-Inch T-Bar

You'll need to use an adapter (ADPR-ADP-RT15) along with the mounting bracket (APBR-U) to mount an access point (AP) on a recessed 15/16-in. ceiling T-bar. You need to order the ADPR-ADP-RT15 adapter separately.
  1. Attach the ADPR-ADP-RT15 adapter to the T-bar.
    Figure 13: Attach the ADPR-ADP-RT15 Adapter to the T-Bar Sliding mechanism with green arrows indicating pull or push action and black arrows showing sliding direction.
  2. Attach the universal mounting bracket (APBR-U) to the adapter. Rotate the bracket until you hear a distinct click, which indicates that the bracket is locked in place.
    Figure 14: Attach the Mounting Bracket (APBR-U) to the ADPR-ADP-RT15 Adapter Mechanical component alignment with green arrows indicating rotational movement and direction of flow for adjustment.
  3. Position the AP such that the keyholes of the mounting bracket engage with the shoulder screws on the AP. Slide and lock the AP in place.

Mount an Access Point on a Recessed 9/16-Inch T-Bar or Channel Rail

To mount an access point (AP) on a recessed 9/16-in. ceiling T-bar, you'll need to use the ADPR-ADP-CR9 adapter along with the mounting bracket (APBR-U).
  1. Attach the ADPR-ADP-CR9 adapter to the T-bar or channel rail.
    Figure 16: Attach the ADPR-ADP-CR9 Adapter to a Recessed 9/16-Inch T-Bar Drawer slide mechanism diagram with metal track and sliding component. Arrows indicate movement direction; green arrow suggests assembly or disassembly point.
    Figure 17: Attach the ADPR-ADP-CR9 Adapter to a Recessed 9/16-Inch Channel Rail Diagram of a rail or slide mechanism with green arrows indicating movement direction for installation or operation instructions.
  2. Attach the universal mounting bracket (APBR-U) to the adapter. Rotate the bracket until you hear a distinct click, which indicates that the bracket is locked in place.
    Figure 18: Attach the APBR-U Mounting Bracket to the ADPR-ADP-CR9 Adapter Technical illustration of a switch or connector on a rail system with green arrows indicating rotational movement and directional flow.
  3. Position the AP such that the keyholes of the mounting bracket engage with the shoulder screws on the AP. Slide and lock the AP in place.
    Figure 19: Attach the AP to a Recessed 9/16-in. T-Bar or Channel Rail Cable routed through securing device with directional arrows. Green arrow shows cable movement. Number 15/16 indicates measurement.

For recessed channel ceilings, we use this mount as shown to clip onto the channel. You could then attach the BRU just like you did with the T-bar install shown earlier. To remove it, it's the same process. Sometimes you need to mount to a recessed T-bar and this is the adapter for that, the same theory as the channel adapter.

Mount an Access Point on a 1.5-Inch T-Bar

To mount an access point (AP) on a 1.5-in. ceiling T-bar, you'll need the ADPR-ADP-WS15 adapter. You need to order the adapter separately.
  1. Attach the ADPR-ADP-WS15 adapter to the T-bar.
    Figure 20: Attach the ADPR-ADP-WS15 Adapter to a 1.5-Inch T-Bar Diagram of drawer slide mechanism showing side view of drawer movement with green arrows indicating pull-out and push-in directions.
  2. Attach the universal mounting bracket (APBR-U) to the adapter. Rotate the bracket until you hear a distinct click, which indicates that the bracket is locked in place.
    Figure 21: Attach the APBR-U Mounting Bracket to the ADPR-ADP-WS15 Adapter Component installation on DIN rail with green arrows indicating tilt and rotation; left shows tilted position, right shows secured position.
  3. Position the AP such that the keyholes of the mounting bracket engage with the shoulder screws on the AP. Slide and lock the AP in place.

To mount an AP21 or a BT11 on a 5/8-in. threaded rod, you'll need to use the APBR-T58 bracket. that you'll need to order separately.
  1. Attach the APBR-T58 bracket to the threaded rod by using the lock washer and nut provided.
    Figure 23: Attach the APBR-T58 Bracket to a 5/8-in. Threaded Rod Threaded rod installation into base plate with direction arrow indicating insertion. Base plate has slots and holes for mounting.
  2. Attach the APBR-SW1 bracket adapter to the APBR-T58 mounting bracket using two screws (provided with the AP).
    Figure 24: Attach the APBR-SW1 Bracket Adapter to the APBR-T58 Mounting Bracket Exploded view diagram of a mounting plate assembly with a threaded rod, nut, slotted plate, cover with screw holes, and green arrow indicating assembly direction.
  3. Position the AP such that the shoulder screws on the AP engage with the keyholes of the mounting bracket. Slide and lock the AP in place.
    Figure 25: Mount the AP on a 5/8-in. Threaded Rod Mounting process for a device showing a base unit with ports and a mounting plate being aligned and secured by green arrows.

Now if you need to mount a BT11 which is our Bluetooth-only unit to this threaded rod mount, there's a special adapter provided as shown. There are two special screw holes provided and those screws are shipped with the bracket. The bracket to a BT11 there are four indentations as shown which the bracket will clip into. To remove, depress the latches as shown and it will slide back out. Now you use the 2 screws to connect both brackets and attach the BT11.

Mount an AP21, AP45 or a BT11 on a 16-mm Threaded Rod

To mount an access point (AP) on a 16-mm threaded rod, you'll need the APBR-M16 bracket.
  1. Attach the APBR-M16 bracket to the threaded rod by using the lock washer and nut provided.
    Figure 26: Attach the APBR-T58 Bracket to a 16-mm Threaded Rod Threaded rod being inserted into threaded cylindrical component on base plate, indicated by green arrow.
  2. Attach the APBR-SW1 bracket adapter to the APBR-M16 mounting bracket using two screws (provided with the AP).
