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.

Catalyst 9300-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.

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 Help → 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 DHCP 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 DHCP 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 Catalyst Meraki C9300, 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:

Navigate to Switch > Switch ports
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
Select all trunks configured with the allowed VLANs of 1-1000
set to new list including new range of VLANs. (example: 1,100-200,300-400,2100-2200,3000-3100)
Click Update

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.

Please make sure that the DHCP 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 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.

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:

2. Align the rack mount brackets on the sides of the switch onto the rack.

3. Secure and screw in the rack mount bracket on to the rack.

4. Insert the Uplink module.

Note: The C9300 10G and 40G SFP+ and QSFP+ uplink modules are hot-swappable.

Stack Cabling Installation

Connect the cable to the stack port on the switch back panel (as shown in the back panel diagram). Align the connector and connect the stack cable to the stack port on the switch back panel and finger-tighten the screws (clockwise direction). Make sure the Cisco logo is on the top side of the connector.
Connect the other end of the cable to the port on the other switch and finger-tighten the screws. Avoid over tightening the screws.

Please refer to these instructions here before stacking C9300 out of the box.

StackPower Cabling Installation

StackPower on C9300 supports a ring topology of up to 4 switches.
Connect the end of the cable with a green band to either StackPower port on the first switch (see back panel diagram to locate the StackPower ports). Align the connector correctly, and insert it into a StackPower port on the switch rear panel.
Connect the end of the cable with the yellow band to another switch. Hand-tighten the captive screws to secure the StackPower cable connectors in place.
StackPower feature doesn't need any dashboard configuration but is automatically enabled when the cables are installed.

Basic Troubleshooting

The following steps can be used for troubleshooting basic connectivity issues with your switch.

Factory reset the switch by holding the factory reset button for 10-15 seconds
Try switching cables, or testing your cable on another device
