Cisco Meraki MS390-48P 48-Port PoE+ Gigabit Switch — 437 W PoE Budget, Layer 3 Stackable Access Switch, 1U Rack
The Cisco Meraki MS390-48P provides 48 ports of PoE+ Gigabit connectivity with a 437 W PoE budget for powering IP phones, cameras, and 802.11ac access points across an enterprise floor or building. Layer 3 switching with full routing, DHCP, and VRRP support integrates natively with Meraki’s cloud dashboard for centralized policy management. A 256 Gbps switching fabric, modular 10G/40G uplinks, and 480 Gbps stacking with StackPower ensure the platform scales with deployment growth. Field-replaceable, hot-swappable fans and PSU support continuous operation during maintenance.
