Factory Reset Button
If the button is pressed and held for at least five seconds and then released, the switch will reboot and be restored to its original factory settings by deleting all
configuration information stored on the unit.
Ports and Status Indicators
The MS uses LEDs to inform the user of the device's status. When the device powers on, all the Internet LEDs flash twice. Additional functions are described
below, from left to right.
Function LED Status Meaning
Power Solid orange Switch is unable to connect to the Meraki cloud
Flashing white Firmware upgrade in process
Solid white Switch is fully operational and connected to the Meraki cloud
Off Switch does not have power
Restore N/A Restore button to clear switch IP and local configuration settings
Switch Ports Off No link is detected on this port
Flashing orange (R 45 ports only) Activity indicator
Solid green 1 Gbps link detected
Management Interface Green Connected, used for easy access to the local status page
In addition, there is a RESTORE button available on the front panel.
Insert a paperclip if a restore is required.
•A brief, momentary press: To delete a downloaded configuration and reboot.
•Press and hold for more than 10 sec: To force the unit into a full factory restore.
Equipment is to be used only in a restricted access location and installed/operated only by trained service personnel.
Package contents
In addition to the MS switch, the following are provided:

Rack Mount Kit includes:
▪ US 12-24 mounting screws and cage nuts, 5 of each
▪ INTL M5 mounting screws and cage nuts, 5 of each
▪ INTL M6 mounting screws and cage nuts, 5 of each

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 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 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 a switch to your network. For detailed instructions about creating, configuring and managing
Meraki 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 switches or create a new network.
3. Add your switches to your network. You will need your Meraki order number (found on your invoice) or the serial
number of each switch, 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 switch on the map by clicking and dragging it to the location where
you plan to mount it.

Check and Set Firmware
To ensure your switch performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your
switch.
1. Attach your switch to power and a wired Internet connection.
2. The switch will turn on and the power LED will glow solid orange.
3. If the unit requires an upgrade, the power LED will begin blinking white until the upgrade is complete, at which
point the LED will turn solid white. 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 switches must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned.
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 switch. Other features of
the network, such as 802.1X authentication, may rely on the property that the switches have static IP addresses.
Static Assignment
Static IPs are assigned using the local web server on each switch. The following procedure describes how to set the static IP:
1. Using a client machine (e.g., a laptop), connect to the switch over a wired connection.
2. Using a web browser on the client machine, access the switch’s built-in web server by browsing
to http://my.meraki.com. Alternatively, browse to http://1.1.1.100
3. 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).
4. Configure the static IP address, net mask, gateway IP address and DNS servers that this switch will use on its
management connection.
5. If necessary, reconnect the switch to the LAN.
Static IP via DHCP Reservations
Instead of associating to each Meraki switch 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 switches. Please consult the documentation for
the DHCP server to configure DHCP reservations.
