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.
5
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.
6
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.
Installation Instructions
Note: Each MS355 comes with an instruction pamphlet within the box. This pamphlet contains detailed step by step
guides and images to assist in the physical install of the switch.
1. Install the mounting cage nuts in the rack being used for the switch.
2. Separate the rack mount rails, and install the rack mount rails channel onto the rack.
7
7. Insert the power supply unit into the back of the switch. After it has been securely installed, you can connect power to
the power supply unit.
8. (Optional) Install additional SFP+, QSFP+ or QSFP28 units as needed, depending on the compatibility of your model.
Basic Troubleshooting
The following steps can be used for troubleshooting basic connectivity issues with your switch.
• Reset the switch
• Factory reset the switch by holding the factory reset button for 5 seconds
