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.

C9300-M Deployment Best Practices

Before powering on devices or connecting an uplink port to the LAN, ensure to follow the steps outlined below or watch this short video.

Inactive components: When operating in the Meraki-managed mode, the C9300 will disable the RJ45 console port.

Configure your Dashboard Network

To add devices to your Meraki dashboard network please refer to the Creating a Dashboard Account and Organization document.

Check and Set Network Firmware

Ensure that the switch network is set to the correct firmware version. As of September 24th, 2021 MS 14.31 is the recommended version. Recommended

versions are subject to change and are available in each dashboard by navigating to Organization > Firmware Upgrades

You can refer to Managing Firmware Upgrades for steps to set network firmware to the desired version.

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 under elp → Firewall info. The help button is located on the top right corner of any dashboard page. For more

information refer to Upstream Firewall Rules for Cloud Connectivity.

Stacking

For stacking please refer to this section Stack Cabling Installation

Assigning an IP Address

All switches must be assigned routable IP addresses. These IP addresses can be dynamically assigned via D CP or statically assigned. C9300 switches can

support a total count of 1000 VLANs per stand-alone switch or switch stack. VLAN ID 1-1000 are configured by default, however, the active VLANs can be

changed via the local status page or dashboard. When installing an C9300, it is important to ensure that any D CP services or IP address assignments used for

management fall within the active VLAN range.

Note: To utilize any VLANs outside of 1-1000 on a C9300-M, the switch or switch stack must have ALL of its trunk interfaces set to an allowed

vlan list that contains a total that is less than or equal to 1000 VLANs, including any of the module interfaces that are not in use. For example: If a

switch needs to utilize VLANs 1,100-200,300-400,2100-2200,3000-3100,EVERY trunk interface on that switch must be configured with that allowed

VLAN list or a subset of it.

The easiest method to do this is to perform the following:

1. Navigate to Switch > Switch ports

2. in the search bar use the following search term depending on if it is a stack or a single switch:

1. switch:"{name of switch}" is:trunk

2. stack:"{name of stack}" is:trunk

3. Select all trunks configured with the allowed VLANs of 1-1000

4. set to new list including new range of VLANs. (example: 1,100-200,300-400,2100-2200,3000-3100)

5. Click Update

Dynamic Assignment

When using D CP, the D CP 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.

Please make sure that the D CP server used for providing a management IP address to the switch has an available address pool that falls within the active

VLAN range.

Static Assignment

Static IPs can be assigned using the local status page on each switch. For more information on how to configure static IP from the local status page refer to this

documentation.

Static IP via DHCP Reservations

Instead of associating each Meraki switch individually to configure static IP addresses, an administrator can assign static IP addresses on the upstream D CP

server. Through “D CP reservations,” IP addresses are “reserved” for the MAC addresses of the Meraki switches. Please consult the documentation for the

D CP server to conﬁgure D CP reservations.

Check upstream VLAN configuration

Ensure the upstream switch/router port is configured properly and there is no VLAN mismatch.

Check STP configuration

Meraki-managed C9300 series switches run a single instance of MST out of the box. Please refer to this document for interoperability.

Device reboot/ reset precaution

After powering on the unit or a device reboot, the power LED goes through the following cycle -

1. Solid amber

2. Cycle through different colors

3. Solid white if dashboard connectivity is successful or, remain solid amber if dashboard connectivity is unsuccessful. Different power LED colors and their

interpretation are listed under this section. It may take some time for a device to boot up so refer to the power LED indicators to understand what the switch is

doing during boot up. Be patient and let the switch complete the whole boot-up process and connect to the Meraki cloud.

Do not power down or reset the device during a firmware upgrade. A device which has its power LED blinking white is indicating that it is going through a

firmware upgrade.

Once the devices are upgraded to the latest version continue configuring other switch features/settings. For details refer to the MS documentation

Installation Instructions

1. Attach the rack mount bracket to both sides of the switch as shown below:
