Features & Benefits (What Makes It Good)

From IP cameras to wireless access points and VoIP phones, these 16 Full PoE+ ports can power devices directly from the switch.

High throughput and low latency: With 36 Gbps of non-blocking switching capacity, your network will not be a bottleneck.

Two gigabit SFP ports for fiber or other high-speed backbone connections are examples of flexible uplinks.

High-level Layer 3 and traffic control features include static routing (IPv4 and IPv6), VLANs, QoS, link aggregation, and more. Improves internal traffic management and performance.

Built-in security features such as
– 802.1X, DHCP snooping
– IP Source Guard
– Dynamic ARP inspection
It helps to guard against unauthorized access and assaults.

Power-saving and silent – Fanless design; power-saving functions while ports are idle or linked down.

Uses / Ideal Scenarios

• Offices that need a hard-wired PoE+ connection for devices (cameras, phones, APs) without installing individual power
• Branch offices that want rock-solid managed switching with Layer 3 capabilities
• Environments that need isolation of guest networks, VLAN segmentation, and security
• When you need uplink over fiber or need to connect with an existing fiber backbone

Technical Knowledge

• It’s a Layer 3 managed switch, so it will be able to handle inter-VLAN routing without slowing down routers.
• PoE+ is ~30W per port (device-dependent), but you’re limited by the total PoE-power budget (120W), so you’ll have to make a choice about what devices you’ll power.
• SFP uplinks provide flexibility: you can employ fiber modules if you have runs longer than a few meters or want more immunity to electrical noise.
• Fanless design = quieter operation, but also needs to ensure ambient temperature is within spec.
