Specifications
MS390 at a Glance
Performance & Switching
Switching capacity: 208–640 Gbps depending on
model. Forwarding rate: up to 476.19 Mpps on multigig models (MS390-24UX / -48UX /
-48UX2). Uplinks: modular 10G (SFP+) or 40G (QSFP+) uplink modules, plus dual 120G
hardware stack ports for high-speed inter-switch traffic.
Ports & Multigig
24-port models: MS390-24, -24P (PoE+), -24U (UPoE), -24UX (24x 100M/1G/2.5G/5G/10G
multigig UPoE). 48-port models: MS390-48, -48P (PoE+), -48U (UPoE), -48UX (36x 2.5G
+ 12x mGbE UPoE), -48UX2 (48x up to 5GbE UPoE). Multigig ports support 802.11ax/Wi-Fi 6/6E access points that exceed 1 Gbps.
Power & PoE
Cisco UPoE (802.3bt): up to 60W per port on U/UX models; PoE+ on P
models. PoE budget: up to 830W with the primary 1100W supply, up to 1800W with a
redundant secondary supply. StackPower: pools and redistributes power across a stack
for resiliency, using dedicated StackPower cables.
Cloud Management & Licensing
Runs on the same hardware platform as the Cisco Catalyst 9300, managed entirely through the Meraki
cloud
dashboard. Supports Layer 3 routing, Layer 7 firewall/traffic shaping, and Adaptive Policy security-group segmentation. Licensed per 24- or 48-port model in Enterprise or Advanced tiers (1/3/5/7/10-year terms); Advanced adds Adaptive Policy and NetFlow/Encrypted Traffic Analytics.
Not sure which MS390 model fits your network?
Compare port counts, PoE budgets, and multigig options side by side across the entire MS390 lineup to
find the right fit for your access or aggregation layer.
The MS390 is designed for high-performance enterprise campus access and aggregation
layers, including environments with dense 802.11ax/Wi-Fi 6/6E access point deployments, high-power PoE
endpoints, and demand for Layer 3 routing at the edge, all managed through the Meraki cloud dashboard.
The MS390 runs on the same switching hardware as the Catalyst 9300, but it ships with
Meraki's cloud-managed operating system instead of Cisco IOS XE. That means zero-touch provisioning,
centralized dashboard management, and built-in analytics, with the same performance and port options
as the Catalyst 9300 line.
Yes. P models support PoE+, while U and UX models support Cisco UPoE (802.3bt) for up
to 60W per port, ideal for powering Wi-Fi 6/6E APs, security cameras, and other high-draw endpoints.
Total PoE budgets range up to 830W on the primary power supply and up to 1800W with a redundant
secondary supply, depending on model.
Yes. The MS390 supports hardware stacking with 480 Gbps of dedicated stacking
bandwidth via dual 120G stack ports, plus StackPower, which pools and redistributes power across the
stack for resiliency and fast failover.
Every MS390 requires a Meraki license matched to its port count (24-port or 48-port)
in either Enterprise or Advanced tiers, available in 1, 3, 5, 7, or 10-year terms. Advanced licensing
unlocks Adaptive Policy segmentation and NetFlow v10/Encrypted Traffic Analytics; Enterprise and
Advanced licenses generally cannot be mixed within the same co-termed organization.
