Meraki MS42P
Cloud-Managed 48-Port Gigabit PoE Switch

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.

Built-In Multi-Site Cloud Management

The Meraki MS is the industry’s first cloud managed switch, combining the benefits of cloud based centralized management with a powerful, reliable access platform.

With cloud management, thousands of switch ports can be configured and monitored instantly, over the web. Provision remote sites without on-site IT, deploy network-wide configuration changes, and easily manage campus and distributed networks without training or dedicated staff.

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 quality-of-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 standards-based 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.

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).

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

Automatic Monitoring, Diagnostics & Alerts

Each Meraki MS is automatically monitored from the cloud, with continuous testing for cable failures, WAN connectivity, and more. The MS notifies you of problems with email alerts, and provides rich web-based diagnostics to troubleshoot your network from any web browser.

Simplified Security & Compliance

Seamless firmware updates, two factor authentication, and other built-in protections make secure, PCI and HIPAA-compliant networks easy and cost effective.

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.

Meraki Cloud Management Architecture

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.

Powerful Hardware Platform

The MS hardware platform is designed for performance, low power and noise, and ultra-high reliability.

Inside the Meraki MS

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 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 MS22 / MS42 switches result in power and cooling savings in large deployment environments of 30-60% when compared with similar managed Gigabit switches.

Accessories

The Meraki MS support pluggable optics for high-speed stacking and core connectivity. Meraki offers several standards-based Gigabit and 10 Gigabit pluggable modules. Each appliance has also been tested for compatibility with several third-party modules.
