Curation Review
- ✔ Pros: Full 1GbE access with PoE+ and PoE++ options across 8 to 48 ports; MP models add 2.5GbE multigig ports for Wi-Fi 6/6E/7 access points; 1G/10G SFP+ uplinks and VC ports; Virtual Chassis stacking for unified management; Fanless 8P and 12-port models suit quiet or small-footprint installs; Layer 2 and Layer 3 feature set; Perpetual PoE keeps powered devices running during switch reboots; 32,000 MAC addresses with per-port and per-VLAN MAC limiting
- ✘ Cons: Published switching capacity and forwarding rate are not confirmed for every model (24MP forwarding rate unclear); VC requires 10GbE SFP+ and is not supported with 10GBASE-T transceivers; 8P has only two SFP+ ports, and only ports 2-3 can become VC ports; Fixed internal PSU with no redundancy option; Layer 3 licensing tier and feature details were not verified against the official datasheet; Prices vary widely by reseller and configuration, and some listings are discounted from list price
- Est. Price: $661 - $5,295
