Cisco Meraki (MS390-48-HW) MS390 48GE L3 Switch

Overview

The Meraki MS390 addresses the most demanding enterprise applications by combining the simplicity of the Meraki dashboard with powerful switching hardware. To satisfy high-bandwidth applications and the deployment of high-speed 802.11ax/wifi-6 access points, the MS390 provides multigigabit ports, 480G stacking, and modular 10/40G uplinks. The MS390 delivers resiliency with fast stack convergence and StackPower. The MS390 provides Adaptive Policy using an over-the-wire tag which segments traffic into security groups to deliver scalable security. The MS390 is integrated under the Meraki dashboard to provide a simply powerful solution to the most demanding wired access applications.

Adaptive Policy provides simple & scalable security policies to segment traffic using Security Groups. Security Groups are created in the dashboard using natural language such as “IOT device” & “Guest.” The security policy intent (e.g., Permit or Deny) is then simply provisioned between Security Groups which results in the segmentation of each group’s traffic. By making security policy management intuitive and scalable relative to legacy IP-address based Access Control Lists, Adaptive Policy empowers operators to confidently secure their network traffic independent of future network changes.

By pooling & distributing power across MS390s using a series of StackPower cables, StackPower provides simple and resilient power distribution across the stack.

MS390 Licensing

MS390 license structure includes two feature tiers: Enterprise and Advanced. The MS390 also introduces a new and simpler license to hardware mapping, specifically 24-port or 48-port licenses. As with all MS, every MS390 license is available in 1, 3, 5, 7, and 10 year terms.

Meraki Support is unable to upgrade licensing from Enterprise to Advanced for the MS390 model. This upgrade must be purchased as a new license.

The features available with advanced licensing are:

• Adaptive policy
• Netflow v10 (IPFIX) and Encrypted Traffic Analytics

In the Co-term licensing model (most existing Organizations), an Organization must either have all MS390 Enterprise or all MS390 Advanced licenses - they cannot be mixed. In the Per-device licensing model, a mix of Enterprise and Advanced can be added to a single Organization, but certain features may require all devices in a Network to have Advanced licenses, e.g. Adaptive Policy.

Note: Catalyst 9300-M series existing in the same co-term Organization will require the same license edition (either Enterprise or Advanced) as the MS390. License types cannot be mixed and will result in an incompatible license error.

MS130, MS150, MS390, C9300 require the same license tier (either Enterprise of Advanced) across the entire Organization.

For more information on licensing, refer to Meraki Licensing Models article.

Subscription licensing is also available for the MS390 switches.

Context and Comparisons

Technical Breakdown

Interfaces Specifications

All models are available with modular uplinks that have been listed under the Accessories list. For supported SFP modules please refer the SFP Datasheet.

Cabling Best Practices for Multi-Gigabit operations: While Category-5e cables can support multigigabit data rates upto 2.5/5 Gbps, external factors such as noise, alien crosstalk coupled with longer cable/cable bundle lengths can impede reliable link operation. Noise can originate from cable bundling, RFI, cable movement, lightning, power surges and other transient event. It is recommended to use Category-6a cabling for reliable multigigabit operations as it mitigates alien crosstalk by design.

Power Options and Specifications

** Upgrade options to 715W and 1100W PSU are available.

*** The PoE values are provided considering the secondary PS to be the default power supply of the respective model.

Note: For Japan, the recommendation is to deploy the switch with 200V+ outlets. The 1100WAC power supply will not operate on 100V. Please reference Table 13. AC Power Cords for the appropriate 250VAC power cable.
