1 Gigabit Ethernet Smart Managed Switches
The D-Link DXS-121 Series conveniently offers a range of 1-Gigabit copper and fiber port combinations to cost-effectively alleviate network congestion. Select models are equipped with SFP+ or SFP28 ports for 1G/25G expandable network designed for scalability and can auto-detect surveillance and voice data to ensure uninterrupted video footage and jitter-free VoIP calls.
Alleviate Network Congestion
Add 1‑Gigabit Ethernet connectivity with these affordable high-performance switches. Designed for deployment in small to medium-sized business (SMB) core networks and powerful enough for enterprise aggregation applications.
Convenient Layer 2 & Layer 3 Lite Configurability
The DXS-121 Series can be deployed as a Layer 2 aggregation switch with features such as port mirroring, STP, and LACP. When implemented as a Layer 3 Lite core switch, IP interfaces, ARP, IPv6 ND, Default Routing, and Static Routing can be applied for efficient routing applications.
An Added Line of Defense Against Attacks
The DXS-121 Series defends your network with D-Link’s innovative Safeguard Engine™ to neutralize threats such as malicious network flooding attacks, ARP spoofing, and bogus DHCP IP addressing. The DXS-121 Series supports 82.1X port-based and host-based authentication, allowing the network to be authenticated through external RADIUS servers.
Unhindered Surveillance & VoIP with a Simple Click
If you need surveillance or VoIP, there is no need to build a dedicated network. With the DXS-121 Series, expediting latency-intolerant services such as surveillance and VoIP through the existing network can’t be any easier. Simply enable the Auto Surveillance VLAN & Auto Voice VLAN features. Your surveillance videos will always run smoothly and your VoIP calls will be crystal-clear from beginning to end, even during peak working hours.
Better for Your Budget, Better for the Planet
When low-traffic or idle interface ports are detected, the DXS-121 Series automatically transitions them into a low-power state, substantially reducing overall device power consumption. Furthermore, the DXS-121 Series can determine the approximate length of cables attached to each port to apply just enough power for data transmission on that link, saving even more power while lowering total cost of ownership (TCO).
