Cisco MERAKI MR57 User manual

MR57 Installation uide
The Cisco Meraki MR57 is a tri-band enterprise-class Wi-Fi 6E cloud-managed access point supporting 2.4 Hz, 5
Hz, and the newly opened unlicensed 6 Hz frequency bands. Designed for the ultra high capacity and highest
density, MR57 meets the needs of the most demanding and mission-critical environments. The access point also
includes a fourth radio dedicated to optimizing the RF environment and securing the airwaves. The MR57 also has an
additional Bluetooth Low Energy (BLE) capable radio used for location and other IoT applications. In addition to this
MR57 has a USB port to support external devices for IoT applications
About this uide
This guide provides instructions on how to install and configure your MR57 access points. This guide also provides

D - Cable access slot
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
4

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).
Note: High Availability and Power Sharing will be available in future firmware versions
Warning: a single 802.3af power source is not supported
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
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
5

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: 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 table below indicates the different modes of PoE power input and the expected operation of the AP
PoE0 PoE1 2.4GHz 5GHz 6GHz Scan IoT USB
AF None Not Supported and AP does not power up

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
6

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
NOTE: Blinking reen LED indicates that the device is in site survey mode. Please see the Conducting Site Surveys
with MR Access Points for more details.
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.
Package Contents
The access point packages contain the following:

Safety and Warnings
These operations are to be taken with respect to all local laws. Please take the following into consideration for safe
operation:
• Power off the unit before you begin. Read the installation instructions before connecting the system to the power
source.
• Before you work on any equipment, be aware of the hazards involved with electrical circuitry, and be familiar with
standard practices for preventing accidents.
• Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to
follow the correct procedures could result in a hazardous situation to people and damage to the system.

• This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective
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.
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
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.
