Pre-install Preparation
You should complete the following steps before going on-site to perform an installation.
Configure your Dashboard Network
The following is a brief overview only of the steps required to add an access point to your network. For detailed
instructions about creating, configuring, and managing Meraki wireless networks, refer to the online documentation
(documentation.meraki.com).
1. Log in to http://dashboard.meraki.com. If this is your first time, create a new account.
2. Find the network to which you plan to add your APs or create a new network.
3. Add your APs to your network. You will need your Meraki order number (found on your invoice) or the serial number
of each AP, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the unit. You will also need your license key,
which you should have received via email.
4. o to the map / floor plan view and place each AP on the map by clicking and dragging it to the location where you
plan to mount it.
Check and Set Firmware
To ensure your access point performs optimally immediately following installation, it is recommended that you facilitate a
firmware upgrade prior to mounting your AP.
1. Attach your AP to power and a wired Internet connection. See the " etting Power to the AP" section for details.
2. The AP will turn on and the LED will glow solid orange. If the unit does not require a firmware upgrade, the LED will
turn either green (no clients associated) or blue (clients associated) within thirty seconds.
* If the unit requires an upgrade, the LED will begin blinking orange until the upgrade is complete, at which point the LED
will turn solid green or blue. You should allow at least a few minutes for the firmware upgrade to complete, depending on
the speed of your internet connection.
Check and Configure Upstream Firewall Settings
If a firewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. The most
current list of outbound ports and IP addresses for your particular organization can be found on the firewall configuration
page in your dashboard.
Assigning an IP Address
All gateway APs (An AP with Ethernet connections to the LAN) must be assigned a routable IP address. These IP
addresses can be dynamically assigned via DHCP or statically assigned.
9

Static Assignment
• Static IPs are assigned using the local web server on each AP. The following procedure describes how to set the static
IP:
• Using a client machine (e.g., a laptop), connect to the AP wirelessly (by associating to any SSID broadcast by the AP)
or over a wired connection.
• If using a wired connection, connect the client machine to the AP either through a PoE switch or a PoE Injector. If using
a PoE switch, plug an Ethernet cable into the AP’s Ethernet jack, and the other end into a PoE switch. Then connect the
client machine over Ethernet cable to the PoE switch. If using a PoE Injector, connect the AP to the “PoE” port of the
Injector, and the client machine to the “LAN” port.
• Using a web browser on the client machine, access the AP’s built-in web server by browsing http://my.meraki.com.
Alternatively, browse to http://10.128.128.128.
• Click on the “Uplink Configuration” tab. Log in. The default login is the serial number (e.g. Qxxx-xxxx-xxxx), with no
password (e.g., Q2DD-551C-ZYW3).
• Configure the static IP address, netmask, gateway IP address, and DNS servers that this AP will use on its wired
connection.
• If necessary, reconnect the AP to the LAN.
Static IP via DHCP Reservations
• Instead of associating to each Meraki AP individually to configure static IP addresses, an administrator can assign
static IP addresses on the upstream DHCP server. Through “DHCP reservations,” IP addresses are “reserved” for the
MAC addresses of the Meraki APs. Please consult the documentation for the DHCP server to configure DHCP
reservations.
Collect Tools
You will need the following tools to perform an installation:
10

Phillips screwdriver, Hammer (optional), Drill with 1/4" (6.3mm) bits (optional) - depending on install type
Collect Additional Hardware for Installation
You will need the following hardware to perform an installation:
802.3bt/at PoE Power Source (either PoE switch or Meraki 802.3bt/at PoE Injector) or an AC adaptor and network
cables with RJ45 connectors long enough for your particular mounting location
Note: CW9162 can be powered by a PoE Switch, PoE Injector or an AC adaptor. Powering up the AP with an AC
adapter while connecting to a PoE source is not recommended. Proper functionality of the AP is not guaranteed and this
can potentially cause damage to the AP hardware.
Installation Instructions
Choose Your Mounting Location
A good mounting location is important to get the best performance out of your access point. Keep the following in mind:
1. The device should have an unobstructed line of sight to most coverage areas. For example, if installing in an office
filled with workspaces divided by mid-height cubicle walls, installing on the ceiling or high on a wall would be ideal.
2. Power over Ethernet supports a maximum cable length of 300 ft (100 m).
3. If being used in a mesh deployment, the AP should have a line of sight to at least two other Meraki devices. A Cisco
Partner and/or site survey can help ensure that your AP placement is ideal.
Install the AP
For most mounting scenarios, the access point universal mounting bracket provides a quick, simple, and flexible means
of mounting your device. The installation should be done in two steps. First, install the universal mounting bracket to
your selected location. Then, attach the AP to the universal mounting bracket.
11

Attaching the Universal Mounting Bracket
The access point universal mounting bracket (AIR-AP-BRACKET-2 - included) can be used to install your access point
in a wide range of scenarios including a wall or solid ceiling, below a drop ceiling, or on various electrical junction boxes.
Wall or Solid Ceiling Mount Using Universal Mounting Bracket
Using included wall anchors and screws, attach the universal mounting bracket to your mounting wall or ceiling. It is
recommended that the AP be mounted to a wall or solid ceiling using the universal mounting bracket for physical
security reasons.
Drop Ceiling Mount using T-Rail Mount attachment
To mount your AP on a drop ceiling T-rail (AIR-AP-T-RAIL-R - included), use the included T-Rail mount attachment. The
T-Rail mount attachment can be used to mount to most 9/16”, 15/16” or 1 ½” T-rails.
1. Place the ceiling grid clip over the T-rail and close it to the appropriate detent (A, B, or C).
2. Use a screwdriver to tighten the two ceiling grid clip locking screws to prevent the clip from sliding along the T-rail.
3. Observe the ceiling grid clip width detent letter (A, B, or C) that corresponds to the T-rail width.
12

4. Align the corresponding holes (A, B, or C) on the mounting bracket over the mounting holes on the ceiling grid clip.
5. Hold the mounting bracket and insert a 6-32 x 1/4 in. screw into each of the four corresponding holes (A, B, or C) and
tighten.
13

Wall Mount the AP using Universal Mounting Bracket
To mount the AP on the wall first, identify the location of the wall
1. Use the mounting bracket as a template to mark the locations of the mounting holes on the bracket
2. Use a 0.1360-in. [3.4772 mm] bit to drill a pilot hole at the mounting hole locations you marked.
3. Locate the pilot holes and then insert a fastener(not included) into each mounting hole and tighten.
4. Place the universal mounting bracket over the faster holes and then use screws up to 6 mm in diameter and at least 1
- 1/4 inch length (not included) to tighten it flush to the wall
14

The AP is not ready to be mounted on the wall
Electrical Junction Box Mount Using Universal Mounting Bracket
The access point can be mounted to a 4” square cable junction box, a 3.5 or 4” round cable junction box, or various U.S.
and European outlet boxes (mounting screws are not included).
Using appropriate mounting hardware for your specific type of junction box, attach the universal mounting bracket to the
junction box.
Getting Power to the AP
If mounting to an electrical junction box, feed the Ethernet cable through the cable access hole in the universal mounting
15

bracket. If mounting to a wall or ceiling, the Ethernet cable will feed from behind the AP. The "Power Source Options"
section of this document lists the different powering options and their unique characteristics.
Mount the AP
Attach the AP to the Universal Mounting Bracket
(Picture for Wall mount section and Picture for ceiling mount section )
The AP has four rubber feet that when gently slid in attach to the universal mounting bracket
To attach the AP to the universal mounting bracket properly, align the access point feet over the keyhole mounting slots
on the mounting bracket. Since the cradle is already mounted to the wall, gently guide the AP towards the mounting
cradle until it clicks into place.
Physical Security
Depending on your mounting environment, you may want to secure the AP to its mount location. The access point can
both be secured in several ways. If the AP has been installed using the universal mounting bracket, it should be secured
via a security screw and/or Kensington lock. If the universal mounting bracket was not used, the AP can still be secured
using a Kensington lock.
16

Kensington Lock
The access point contains a hard point that allows it to be secured to any nearby permanent structure using a standard
Kensington lock. Attach a Kensington lock cable to the access point at the hardpoint on the side of the device. Attach
the other end of the cable to a secure location, such as a pipe or building fixture.
Verify Device Functionality and Test Network Coverage
• Check LED
◦ The Power LED should be solid green (or blue, if clients are connected).
◦ If it is flashing blue, the firmware is automatically upgrading and the LED should turn green when the upgrade
is completed (normally within a few minutes). See the "LED Indicators" section for more details.
Your AP must have an active route to the Internet to check and upgrade its firmware.
• Verify access point connectivity
◦ Use any 802.11 client device to connect to the AP and verify proper connectivity using the client’s web browser.
• Check network coverage
• Confirm that you have good signal strength throughout your coverage area. You can use the signal strength meter
on a laptop, smartphone, or another wireless device.
6GHz Configuration
The 6 Hz frequency band for the CW9162 can be enabled from the RF Profile page in the dashboard
Wireless > CONFIGURE > Radio Settings>RF Profiles
6 Hz band is enabled using the drop-down menu, 6 Hz capability can be enabled for all SSIDs
or an SSID that would require 6 Hz capability.
17

Preferred Scanning Channels
The 6 Hz frequency band introduces 59 20 MHz channels. Due to a large number of channels, the standard
implements a new efficient process for clients to discover nearby access points. This is called Preferred Scanning
Channels (PSC). PSCs are a set of 20-MHz channels that are spaced every 80 MHz. In order to support the PSC-based
clients and effectively onboard the clients in the least possible time, the 6 Hz channel selection in the RF profile for
CW9162 Auto RF configuration will be restricted to a set of PSC capable channels.
The list of the PSC channels is indicated above in green. Auto RF will choose a channel that is a PSC-supported
channel for 20, 40, 80, and 160 MHz frequencies.
Note: When disabling a channel that is being used by Auto Channel configuration settings, the system will make sure to
disable all 80 MHz of the closest PSC channel.
Warning: Please make sure to assign a PSC-supported channel when allocating a channel manually. There could be a
substantial delay in the client connecting to the Access Point if a non-PSC supported channel is selected during manual
allocation
WPA3 Support
WiFi 6E in the 6 Hz frequency band requires the clients to support WPA3 as a mandatory mode of operation.
WPA2-WPA3 transition mode is not supported in the 6 Hz frequency. If an SSID is configured to operate across all
three frequency bands, then the SSID should be configured to be WPA3 only
Note: If an SSID is configured to support WPA3 transition mode across all three frequency bands, then the 2.4 Hz and
the 5 Hz frequency will broadcast the SSID with transition mode support. The SSID will not be broadcasted in the 6
Hz mode
Basic Troubleshooting
The following steps can be used for troubleshooting basic connectivity issues with your access point.
• Reset the access point
• Factory reset the access point by holding the factory reset button for 5 seconds
• Try switching cables, or testing your cable on another device
18

If your access point still does not connect, the following instructions may be useful, depending on your issue.
Check Radio Functionality by Making the AP a Repeater
1. If your AP is acting as a gateway, disconnect the Ethernet cable from the LAN (while keeping the AP powered on).
This will switch your AP into repeater mode. If no other gateways are within range, the AP will begin broadcasting an
SSID appended with "-scanning". If you are able to connect to this SSID and go to my.meraki.com from your web
browser, then your radio is working.
2. Physically place the repeater AP (AP with disconnected LAN) next to a working gateway AP.
3. Connect the power adapter or PoE. The radio and signal strength LEDs on the AP will turn solid green or blue once
the access point boots up and detects the gateway.
4. The access point is now a repeater and will check into the Dashboard.
5. On the Wireless > Access Points page in the Dashboard, you will see the connectivity bar for the specific Repeater
AP reflecting a light green color, which means the AP is a repeater. ateway APs will reflect a dark green color in the
connectivity bar and also will have the letter ( ateway) on top of the AP symbol.
Check Ethernet Port Functionality by Connecting to the AP
1. Disable the Wireless adapter on your computer.
2. Make sure the Ethernet adapter on your device is set to obtain an IP address automatically via DHCP.
3. Connect your computer to the Ethernet port on the AP with an Ethernet cable.
4. The Ethernet LED on the AP should turn solid green or blue.
5. If the Ethernet LED does not turn solid green or blue, try swapping the cable. If the Ethernet port still does not turn
green or blue, try the second Ethernet port, if the AP has one.
6. If the Ethernet LED does not turn solid green or blue, you may have a bad port on the AP. If this is the case, the AP
signal LEDs will continue to scan.
7. Once the Ethernet LED turns solid green or blue, your computer should obtain an IP address from the AP via DHCP.
Check Static IP Address Configuration
1. If the AP has a static IP address, the green signal LEDs will begin to flash on and off and you will not receive an IP
address via DHCP.
2. Disconnect the Ethernet cable from the AP.
3. Associate to the SSID being broadcasted by the AP. If there are no other APs in the network within range the SSID
19

may be appended with "-scanning".
4. o to my.meraki.com in your web browser.
5. The MAC address on the back of the access point should match the physical address value on the my.meraki.com
Overview page.
6. Once you have verified that the MAC address is correct on the overview tab, click the tab Static IP configuration.
7. Enter the username (serial number on the back of the AP) which is case sensitive and must include the dashes.
(There is no password).
8. Make sure your AP is set to obtain a correct DHCP or static IP address configuration from your network.
