With a total of 48 ports, the MS390-48U-HW offers a high port density. This makes it an ideal choice for medium to large-sized networks where numerous devices need to be connected. Whether you're setting up workstations, IP cameras, VoIP phones, or access points, this switch has you covered with ample ports.

The "48P" in the name signifies that this switch provides Power over Ethernet (PoE) on all 48 ports. PoE simplifies the deployment of network devices by delivering both data and power over a single Ethernet cable. This feature is particularly valuable for IP phones, security cameras, and access points as it eliminates the need for additional power sources and simplifies cable management.

The "Layer3 (L3)" designation indicates that the MS390-48U-HW is a Layer 3 switch, which means it is capable of routing traffic between different subnets or VLANs. Layer 3 switches are essential for creating efficient and segmented networks, optimizing traffic flow, and enhancing network security.

The switch offers support for 10/100/1000 Mbps Ethernet speeds, commonly referred to as Gigabit Ethernet. This versatility in speed accommodates a wide range of devices and applications, from standard workstations to high-bandwidth servers and data-intensive tasks. Gigabit Ethernet provides data transfer speeds of up to 1,000 Mbps, making it suitable for bandwidth-intensive applications, such as video streaming and large file transfers.

With the Quad Small Form-Factor Pluggable (QSFP) uplink ports, the MS390-48U-HW provides high-speed data transfer capabilities. Uplink ports are used to connect the switch to the core of the network, ensuring that data can flow smoothly and quickly to and from the switch.

UPoE support is a remarkable feature that allows the switch to deliver even more power to connected devices. This is beneficial for devices that demand higher power levels, such as video conferencing equipment, advanced security cameras, and access points with multiple radios and additional features.

The inclusion of "Meraki Cloud" in the name signifies that this switch is designed to be managed and monitored through the Cisco Meraki cloud platform. Cloud management simplifies network administration by providing a centralized and accessible interface for configuration, monitoring, and troubleshooting.
