Description

Compact edge switch combining 16x 1G access with 4x 2.5G mGig for high‑throughput clients and Wi‑Fi 6/6E APs. Two 10G SFP+ uplinks provide resilient aggregation to core or distribution. PoE+ powers APs, VoIP phones, and cameras while L2/L3‑lite features, QoS, and security controls simplify segmentation and prioritization. Ideal for branch offices and SMB wiring closets needing multigig with 10G uplinks.

Features

- Mixed 1G and 2.5G mGig access for modern APs and high-speed clients
- 2x 10G SFP+ uplinks for high-bandwidth aggregation and redundancy
- PoE+ to power APs, phones, and cameras from the switch
- Enterprise QoS and security to segment and prioritize critical traffic
- L3-lite (static routing) for simple inter-VLAN routing at the edge
- Flexible management via web, CLI, and SNMP

FAQs

Q: Do the 2.5G mGig ports also support 5G?
A: These ports support 100M/1G/2.5G via 802.3bz. 5G support is not indicated for this SKU.

Q: Which uplink optics are supported?
A: 10G SFP+ SR/LR and DAC/AOC are commonly supported; 1G SFP modules are typically supported in downshift mode. Check the platform’s compatibility list for approved part numbers.

Q: Is a software license required?
A: Base functionality is covered under Network Essentials. Advanced features may require additional licensing on some platforms.

Q: What is the PoE power budget?
A: The total PoE budget depends on the installed power supply and configuration. Contact us with your load requirements for sizing.

Q: Can I use this in a small branch without a core switch?
A: Yes. With L2 features and basic L3 (static routing), it fits small branches; use the 10G uplinks for WAN/aggregation as needed.
