Description
Condition: NEW — Brand new, factory-sealed unit.
Manufacturer Part #: MS390-24U-HW
Cisco Meraki MS390-24U 24-Port UPoE Gigabit Switch — 830 W PoE Budget, Layer 3 Stackable Access Switch, 1U Rack
The Cisco Meraki MS390-24U provides 24 ports of UPoE connectivity with an 830 W PoE budget, capable of delivering up to 60 W per port for 802.3bt-compliant devices such as next-generation Wi-Fi 6 access points and high-power IP endpoints. Layer 3 switching with static and dynamic routing, DHCP server/relay, and VRRP warm spare keeps enterprise traffic flowing reliably. The modular uplink design supports up to 8 × 10G SFP+ or 2 × 40G QSFP+ modules for upstream connectivity. Cisco StackPower shares PSU capacity across the stack for added power redundancy.
