Security Features

The MR57 features multiple options for physically securing the access point after installation:

1. Security hasp – The universal mounting bracket has a security hasp and can be used to secure the access point to the universal mounting bracket. Engaging

the security screw prevents accidental dislodging and theft.

2. 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.

Ethernet Ports

The MR57 features two RJ45 Ethernet ports capable of operating at 100/1000/2.5 /5 BASE-T Ethernet (RJ45). The Ethernet ports can also be combined for

link aggregation for an effective data rate of up to 10 bps

The labeled “ETH0, PoE” accepts 802.3 af (in power sharing mode), 802.3at and 802.3bt power. This port is typically used as the primary uplink to your LAN/

WAN.

The labeled “ETH1, PoE” can also accept 802.3 af (in power sharing mode), 802.3at and 802.3bt power. This port is typically used when the AP needs to

support High Availability* in case of primary port failure or Power Sharing* (when two 802.3af power sources are combined to provide 802.3at power or two

802.3at power sources are combined to provide 802.3bt power).

Link Aggregation

The two Ethernet ports can be used in a bonded configuration. Ensure that the AP is plugged into 2 switch ports on the same Ethernet switch that has been

configured for LACP bonding. Keep in mind that the maximum bonded aggregate 10 ig wired connection to the switch. See the MR Link Aggregation

Configuration uide for more details.

Extending the LAN

Edit

section

If only 1 Ethernet port is used to link the AP to the LAN/WAN, the second Ethernet port may be used to connect devices that do not have wireless capability. In

order to utilize the additional LAN port to extend connectivity, a Port Profile needs to be applied to AP.

Note: High Availability and Power Sharing will be available in future firmware versions

Warning: The AP will not power up with a single 802.3af power source

Warning: Some of the pre-standard 802.3at/PoE+ switches do not negotiate full 802.3at power output with the MR57 by default. For these switches

(Cisco Catalyst 2960,3560, etc) the switch port that is connected to and powering up the MR57 should be manually configured to provide 30 watts of

power. This can be done by going into the interface of the switch and setting the inline power to 30 watts using the following command

power inline consumption 30000

before actually powering up the AP. Failure to do so may result in the MR57 not receiving enough power to operate and can remain in low power

which can cause the APs to continuously reboot

Note: When link aggregation is disabled, Eth0 should be used as the primary uplink and POE port.

Power Source Options

MR57 can be powered by dual M- ig 802.3 bt capable PoE ports. The two Ethernet ports are capable of combining the power of two 802.3 af/at power to

provide 802.3 at/bt. The AP is capable of operating at its full capacity when powered by a single 802.3bt power at full capacity. All the AP radios will run at full

capacity, however, the USB port will be disabled when powered by a single 802.3 at power. The AP will not power up when powered by a single 802.3af power

source.

The table below indicates the different modes of PoE power input and the expected operation of the AP

BT None 4x4 4x4 4x4 ON ON ON

BT BT 4x4 4x4 4x4 ON ON

MR57 APs can be powered by the PoE power in different modes as mentioned above when using a PoE-capable switch. MR57 can also be powered by a single

802.3bt capable PoE injector MA-INJ-6 - Meraki multi igabit 802.3bt Power over Ethernet Injector. It can also be powered by an AC power adaptor MA-

PWR-50WAC Meraki AC Adapter for MR Series

Factory Reset Button

If the button is pressed and held for at least ﬁve seconds and then released, the AP will reboot and be restored to its original factory settings by deleting all

configuration information stored on the unit.

LED Indicators and Run Dark Mode

Your access point is equipped with a multi-color LED light on the front of the unit to convey information about system functionality and performance:

• Orange - AP is booting (permanent Orange suggests hardware issue)

• Rainbow - AP is initializing/scanning

• Blinking Blue - AP is upgrading

• reen - AP in ateway mode with no clients

• Blue - AP in ateway mode with clients

• Blinking Orange - AP can't find uplink

The MR57 access point may be operated in the “Run Dark” mode for additional security and to reduce the visibility of the access point. In this mode, the LED will

not be illuminated. This mode may be enabled through the Meraki Dashboard.

device is rated not greater than 15 A, 125 Vac, or 10A, 240 Vac.

• Please only power the device with the provided power cables or standard PoE to ensure regulatory compliance.

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. Login 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

Warning: If the Networks in the Organization where the MR57 is to be installed have Meraki Sensors, it is required to create a separate network for

the MR57 for staging purposes. Once the MR57 connects to the cloud and updates the new firmware, then the AP can be moved to the network

where the MR57 needs to operate

DHCP or statically assigned.

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

to 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:

Phillips screwdriver, Hammer (optional), Drill with 0.1360-in. [3.4772 mm] (optional) - depending on install type

Collect Additional Hardware for Installation

You will need the following hardware to perform an installation:

PoE Power Source (either PoE switch or Meraki PoE Injector) or an AC adaptor and network cables with RJ45 connectors long enough for your particular

mounting location

Note: The universal mounting when attached directly to a wall or a ceiling requires four #8 screws (not included)

Note: MR57 can be powered by two combined 802.3af power source input into Eth0 and Eth1 ports of the Access Points. This will be available in

future firmware versions. MR57 cannot be powered by a single 802.3af power source.

Note: MR57 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. The functionality of the AP is not guaranteed and 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 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.

Attach 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 wall or solid ceiling or below a drop ceiling.

The mount cradle contains a variety of hole patterns that are customized for each installation scenario. The mounting template (included inbox with mount

cradle) should be used to drill holes for wall mounts and also to identify the correct hole patterns in the mount cradle that should be used for each type of mount.

The included mount cradle template shows the hole patterns that should be used for each type of mount.

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 Universal Mounting Bracket

To mount your AP on a drop ceiling T-rail, use the included T-Rail mount attachment - AIR-AP-T-RAIL-R. The included T-Rail mount attachment can be used to

mount on 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).

Warning: Due to the heat dissipation in the back of APs during normal operation, please do not stack powered on APs on top of each other during

pre-installation to avoid heat damage.

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.

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.

MR57 is now ready to be mounted on the drop ceiling

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.

Note: The above mounting procedure is also applicable when using AIR-AP-BRACKET-1 and AIR-AP-T-RAIL-F is used

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

MR57 is now ready to be mounted on the wall

Getting Power to the AP

If mounting to an electrical junction box, feed the Ethernet cable through the cable access hole in the mount cradle. If mounting to a wall or ceiling, the Ethernet

cable will feed on 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 MR57 AP to the Mount Cradle

(This section applies to wall and/or solid ceiling, drop ceiling, or electrical junction box mount where you have already installed the mount cradle.)

The MR57 AP has four rubber feet that when gently slid in attaches to the universal mounting bracket
