Product Features

48 × Gigabit PoE+ Ports

Provides 48 full 10/100/1000 Mbps RJ-45 ports supporting PoE+ (IEEE 802.3at) so you can power compatible devices like wireless access points, IP cameras or VoIP phones directly via Ethernet cabling, eliminating the need for separate power supplies.

4 × 1 Gigabit SFP Uplinks

Includes 4 dedicated gigabit SFP uplink ports (for fiber or copper SFP modules) that enable flexible and long-distance backbone connections or inter-switch links, helping you extend your network reach and wiring closet architecture.

High-Capacity Switching Performance

With a switching capacity of approximately 104 Gbps and a forwarding rate of ~77.38 Mpps for 64-byte packets, this switch can handle high traffic loads, large file transfers, and dense device deployments without becoming a bottleneck.

Advanced Security and Management Features

Offers enterprise-class network safeguards including IEEE 802.1X authentication, IP-MAC binding, DHCP snooping, dynamic ARP inspection, ACLs, IPv6 first-hop security, and more. It supports VLANs, link aggregation (LACP), QoS, and basic static routing, giving you flexibility and control.

Energy Efficiency and Rack-Mount Design

Supports Energy Efficient Ethernet (IEEE 802.3az) and is designed for rack-mount deployment (1 RU height). Its metal chassis and internal power supply make it suitable for professional installations in wiring closets or server rooms.
