Meraki MS22 / MS42 - Cloud Distribution

DATASHEET 

Meraki MS22 / MS42 

Cloud Managed Gigabit PoE Switch Family 

Overview 

The Meraki MS line of cloud-managed access switches bring the 

benefits of cloud computing, including management simplicity, 

reduced complexity, and lower cost, to branch and campus networks. 

A Fresh Approach 

Meraki switches are built from the ground up to be easy to 

manage without compromising any of the power and flexibility 

traditionally found in enterprise-class switches. 

For example, Meraki switches are managed through an elegant, 

efficient cloud interface, rather than a cryptic command line. 

To bring up a Meraki switch, just plug it in; there's no need for 

complicated configuration files. 

In addition, Meraki's centralized management system gives 

administrators deep visibility into the network. See which switches 

are near capacity across hundreds of sites. Find all configuration 

changes made by a certain person with instant search. Locate a 

switch on a floor plan with one click. 

Industry-Leading Cloud Management 

Cloud management has a number of benefits that make it easier to 

build networks large and small: 

• Single pane of glass management of distributed switch 

deployments, wireless APs, and firewalls across multiple sites 

through the browser. 

• Virtual stacking: manage up to 10,000 ports as one. 

• Unified wireless and wired client device information (when used 

in conjunction with Meraki MR-series wireless LAN products). 

• Layer 7 OS and hostname fingerprinting. 

• Automatic cable testing to isolate physical layer issues. 

• E-mail alerts upon power loss or configuration changes. 

• Role-based administration and automatic, scheduled firmware 

upgrades, for PCI compliance. 

• Regular feature updates and enhancements delivered on 

demand from the Meraki Cloud Controller.

Enterprise-Class Hardware 

Meraki switches feature high-end hardware features without the 

high-end price, including: 

• Four built-in small form-factor pluggable transceivers (SFP / SFP+) 

• GbE and 10 GbE uplink ports for high-speed connectivity to 

aggregation layer switches or other upstream devices. 

• Wire-speed switch fabric (up to 176 Gbps) and QoS queues per 

port for converged voice, video, and data deployments. 

• Low power consumption, quiet acoustic designs, and shallow 

rack depth, which enable flexible deployment in wiring closets 

as well as offices and classrooms. 

• 405 watt PoE budget with PoE+ support for powering APs, 

phones, cameras, and other PoE enabled devices. 

• Lifetime hardware warranty and advanced replacement at no 

additional cost. 

Full Enterprise Feature Set 

Meraki switches include all of the traditional Ethernet features 

found on the highest end products, including: 

• Link aggregation for high-capacity trunking and stacking 

• Broadcast storm protection, spanning tree, and other safeguards 

to guard against misconfigurations and reduce convergence time. 

• Per port VLAN configuration 

• Multiple administrative roles with sophisticated security 

policy management 

Converged Voice, Video and Data Environments 

The Meraki switch family is designed to unify data, voice, and video 

onto a single IP backbone. All Meraki switches support rich qualityof-service 

(QoS) functionality for prioritizing data, voice, and video 

traffic. The switches support eight class-of-service (CoS) queues on 

every port, enabling them to maintain end-to-end traffic prioritization. 

PoE models provide 15.4 watts of power per port for VoIP telephones, 

IP security cameras, wireless access points (APs), and 

other IP devices. The Meraki MS switches also support standardsbased 

30 watt IEEE 802.3at for powering networked devices like 

multiple radio IEEE 802.11n APs and video phones that may require 

more power than available with IEEE 802.3af. 

Meraki Cloud Management Architecture 

To ease deployment, the Meraki MS22 and MS42 switches support 

the industry-standard Link Layer Discovery Protocol (LLDP), 

enabling switches to automatically discover Ethernet-enabled 

devices, determine their power requirements and join the correct 

virtual LAN (VLAN).

Meraki's Unified Software Architecture 

The Meraki MS22 and MS42 switches run the same Meraki 

operating system used by Meraki's firewalls and wireless LAN 

products. The use of a common operating system allows Meraki 

to deliver a consistent experience across all product lines. 

Simplified Management and Operations 

Meraki's cloud managed architecture makes it simpler than ever 

to quickly provision and reconfigure switch ports with security, 

QoS, and other parameters. The Meraki Cloud Controller provides 

unified policies, event logs, and monitoring, which make it easy 

to manage and grow large network deployments. 

By providing a complete, powerful set of management functions 

over the web, Meraki's Dashboard system eliminates the need for 

proprietary command line configuration interfaces which require 

expensive or time consuming certifications. Meraki MS switches can 

be fully deployed and provisioned in minutes, without requiring any 

local configuration or staging. Additional or replacement switches 

can be sent to remote offices and installed by non-technical staff, 

saving thousands of dollars in time and travel expense. 

The Meraki MS family also includes several remote diagnostic 

features, from network connectivity and cable integrity tests to 

latency measurement tools. For deep client troubleshooting, 

administrators can even enable remote pcap packet capture 

without any additional probes or hardware on site. 

Designed for Reliability and Environmental Efficiency 

The Meraki MS22 / MS42 switch family was designed for reliable, 

long-lived operation in wiring closet environments, which may be 

prone to high temperatures and limited ventilation. By minimizing 

total component count and only using proven switching silicon, 

Meraki is able to deliver mean time between failure (MTBF) ratings 

of over 475,000 hours on products such as the Meraki MS22. 

Each Meraki switch also operates with a split-plane architecture, 

where silicon-based switching and data forwarding are separated 

from software-based control and management. By decoupling the 


Large Campus 

Branch Office 

underlying switching logic from control, each unit is able to deliver 

wire-speed switching even when advanced software features such 

as Layer 7 host and OS fingerprinting are enabled. 

Finally, the highly integrated designs of Meraki MS 22 / MS42 

switches result in power and cooling savings in large deployment 

environments of 30-60% when compared with similar managed 

Gigabit switches. 

Distributed Branches and Remote Sites 

Meraki's cloud-based system makes it easy to manage a single 

switch, or thousands of distributed switches, from a single interface. 

• Troubleshoot problems remotely, e.g., find which port has a bad 

cable attached. 

• Add or replace switches without having to send a technician 

onsite. Switches automatically download their current 

configuration as soon as they are connected to the network. 

• Receive email alerts or SMS messages whenever there's a 

problem at a remote site. 

Campus Edge 

MS switches are ideal for small and large scale campus deployments, 

where reliability, scalability, and managability are top priorities. 

• Virtual Stacking lets administators manage up to 10,000 ports in 

a single interface without having to pre-define stack members. 

• 10 GbE cable SFP+ ports with link aggregation provide high 

speed connectivity to distribution or core switches. 

• Get alerts when any switch fails or goes offline, before 

users complain. 

Lifetime Warranty with Next-day Advanced Replacement 

Meraki MS22 and MS42 switches include a limited lifetime 

hardware warranty that provides next-day advance hardware switch 

replacement as long as the original purchaser owns the product. 

Meraki's simplified software and support licensing model also 

combines all software upgrades, centralized systems management 

and phone support under a single, easy-to-understand model.
