QNAP QSW-M5216-1T - Managed Layer 2 network switch, Black

The QNAP QSW-M5216-1T Managed L2 Switch (16x SFP28 25GbE + 1x 10GbE RJ45) provides fiber connectivity for server rooms and NAS environments. Equipped with 16 SFP28 fiber slots and one 10GbE RJ-45 copper port, this Layer 2 device supports high-speed networking hardware. An 820 Gbit/s total switching capacity handles heavy network traffic. Forwarding decisions rely on a 32,000-entry MAC address table, while built-in static routing manages paths between internal subnets, allowing the configuration to consolidate multiple links into a single backbone.

The unit measures 285 mm in width and 43.5 mm in height, facilitating mounting in standard server racks. It is a non-PoE, non-stackable model with a maximum power consumption of 80 W. Administrators can configure settings via a web management interface or the dedicated RJ-45 console port. Network management features include VLAN support, Quality of Service (QoS) prioritization, and Access Control List (ACL) rules for network segmentation. Protocols such as IGMP snooping, link aggregation, and loop protection ensure stable data delivery across complex deployments.

• Jumbo frame support (up to 9,000 bytes) to reduce packet processing overhead during large data transfers.
• Built-in DHCP server for automatic IP address assignment to attached devices.
• Port mirroring for real-time network traffic analysis and diagnostics.
• Firmware-upgradeable architecture with an event log to track operational history.
• Weight of 2,150 g and a depth of 237.7 mm for infrastructure planning.
