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).

Login to http://dashboard.meraki.com. If this is your ﬁrst time, create a new account.
Find the network to which you plan to add your switches or create a new network.
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.
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.

Attach your switch to power and a wired Internet connection.
The switch will turn on and the power LED will glow solid orange.
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:

Using a client machine (e.g., a laptop), connect to the switch over a wired connection.
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
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, net mask, gateway IP address and DNS servers that this switch will use on its management connection.
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.

Installation Instructions

Note: Each MS125 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. Attach the switch face plate to the cage nuts on the rack.

3. Connect power to the power supply unit.

4. (Optional) Install additional SFP+ units as needed, depending on the compatibility of your model.

Mounting hardware

The mounting hardware includes a rack mount kit for standard 1U racks. When installing the device, make sure that there is sufficient space between the rear of the rack and other obstacles to ensure adequate airflow.

Optional Mid-Mount bracket

MS125 48 port models are designed for an optional MA-MNT-MID-1 mid-mount bracket when using 2-post racks.

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
Try switching cables, or testing your cable on another device

If your switch still does not connect, the following link may be useful, depending on your issue: Troubleshooting an MS Switch
