Cisco Meraki MR53E Bedienungsanleitung
MR53E Installation Guide
The Cisco Meraki MR53E is a dual-band enterprise class 802.11ac Wave 2 cloud-managed access point with support
for external antennas. Designed for highest capacity and highest density, the MR53E meets the need of the most
demanding environments. The access point also includes a third radio dedicated to optimizing the RF environment
and securing the airwaves along with a BLE radio for supporting IoT applications.
Package Contents
The MR53E packages contain the following:
• MR53E Cloud-Managed Access Point
• Mount cradle including built-in level tool
1
• Drop ceiling mount kit
• Wall screws, wall screw anchors, and security screws
• Spare hardware

Understanding the MR53E
Your Meraki MR52 and MR53 both have the following features:

The mount cradle has the following features:

Security Features
The MR53E both feature multiple options for physically securing the access point after installation:
1. Security screw – The accessory kit includes screws that can be used to secure the access point to the mount
cradle. Engaging the security screw prevents accidental dislodging and theft.
2. ensington lock – The access point contains a hard point that allows it to be secured to any nearby permanent
structure using a standard ensington lock.
External Antenna Ports
The MR53E has 6 external antenna ports:
The ports labeled 2.4/5 is meant for client serving radios
6
The port labeled Scan is meant for client serving radios
The port labeled IoT is meant for client serving radios
Ethernet Ports
The MR53E features 2 Ethernet ports:
The labeled “PoE” accepts 802.3at and 802.3af power and should be used as the primary uplink to your LAN/WAN.
The 2nd port may be used for LACP bonding with the PoE port
7
Link Aggregation
The second Ethernet port can be used in a bonded configuration with the "PoE" port. Ensure that the AP is
plugged into 2 switch ports on the same Ethernet switch that have been configured for LACP bonding. eep in
mind that the maximum bonded aggregate bandwidth is 2.0 Gbps. See the MR Link Aggregation Configuration
Guide for more details
Power Source Options
The MR53E access point can be powered using either the Meraki AC Adapter, PoE Injector (both sold separately), or a
third-party PoE switch.
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 MR53E 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
• Green - AP in Gateway mode with no clients
• Blue - AP in Gateway mode with clients
• Blinking Orange - AP can't find uplink
The MR53E may be operated in “Run Dark” mode for additional security and to reduce the visibility of the access point.
In this mode, the LED will not be illuminated.
eep in mind that only the primary uplink will draw PoE.
The MR53E both will function in low power mode when powered by a 802.3af power source. While in low power
mode, MR53E will disable its Air Marshal radio as well as three out of four transmit streams on the 2.4 Ghz
band. Despite being in low power mode, the device can still supply full 802.11ac capabilities.
When using Cisco switches, an extra step may be required to configure the Cisco switch to use LLDP to
communicate with the Meraki MR53E; see the following article for more

Pre-Install Preparation
You should complete the following steps before going on-site to perform an installation.
Configure Your Network in Dashboard
The following is a brief overview only of the steps required to add a MR53E 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 Enterprise license key, which you should have received via email.
4. Go 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 Upgrade Firmware
To ensure your MR53E 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 "Power 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 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 here.
Assigning IP Addresses
All gateway MR53Es (An AP with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP
addresses can be dynamically assigned via DHCP or statically assigned.
9
Dynamic Assignment
When using DHCP, the DHCP server should be configured to assign a static IP address for each MAC address
belonging to a Meraki AP. Other features of the wireless network, such as 802.1X authentication, may rely on the
property that the APs have static IP addresses.
Static Assignment
Static IPs are assigned using the local web server on each AP. The following procedure describes how to set the
static IP:
1. 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.
2. 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.
3. 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.
4. 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).
5. Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on
its wired connection.
6. 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.
