Managed Switch 8 Gigabit Ports + 2x SFP, L2 – DCN S4200-10P-SI

DCN S4200-10P-SI — managed 8× Gigabit + 2× SFP switch for office and surveillance

The DCN S4200-10P-SI is a compact, managed L2 switch with 8 Gigabit Ethernet RJ45 ports and 2 SFP slots for optical modules. The 20 Gbps switching fabric and 15 Mpps forwarding capacity ensure full throughput on all ports at once. The 8,000-MAC-address table, support for 4K VLANs and management via Web GUI, CLI and SNMP make it an ideal choice for small and medium office networks, surveillance installations and access points where fibre uplinks are needed.

Performance and 2× SFP fibre uplinks

The non-blocking 20 Gbps switching fabric handles full duplex traffic on all 10 ports at once, and a packet forwarding rate of 15 Mpps eliminates bottlenecks with small-frame traffic. Two SFP slots accept 1000Base-X optical modules, so you can easily run the uplink over fibre to the network core or a neighbouring building over a distance unreachable for copper. The packet buffer and jumbo 10K frame support underpin the stable transfer of large files and video streams from IP cameras.

Proven manufacturer, support in Europe

DCN (Digital China Networks) is a recognised manufacturer of network solutions with the European branch DCN Europe, part of the Salumanus group — owner of the Fibermarkt store. The warranty is handled within the EU, and you get technical support with no language barrier or intermediaries. The device retains full compliance with the IEEE 802.3 and 802.1Q standards, so it interoperates seamlessly with other manufacturers' infrastructure.

Key features

• 8× Gigabit RJ45 + 2× SFP — eight copper ports 10/100/1000 Mbps and two fibre slots for 1000Base-X optical modules.
• 20 Gbps fabric, 15 Mpps — non-blocking performance on all ports at once.
• VLAN 802.1Q (4K) — network segmentation, traffic isolation and separating guests from the corporate infrastructure.
• Link Aggregation 802.3ad (LACP) — bundling ports for higher throughput and uplink redundancy.
• Spanning Tree (STP/RSTP/MSTP) — loop protection and fast topology reconvergence.
• 8K MAC table, 4K VLAN — headroom for network expansion without replacing hardware.
• QoS (8 queues/port) — prioritisation of VoIP, video and critical traffic.
• ACL and 802.1x security — port access control and traffic filtering.
• IGMP Snooping — multicast traffic optimisation (IPTV, surveillance).
• Web / CLI / SNMP / Telnet management — full control via browser or command line.
• Passive cooling (fanless) — silent operation, ideal for office and reception.
• Compact metal chassis — 265×44×160 mm, desk or cabinet mounting.

Applications — for installers, integrators and administrators

Office network of a SMALL or MEDIUM business: eight Gigabit ports for computers, printers and VoIP phones, with VLAN segmentation separating departments and the guest network. SFP fibre uplink to the server room or main switch.

IP surveillance installation: aggregation of streams from the recorder and cameras, jumbo frame support for high resolution and IGMP Snooping limiting multicast traffic. The SFP uplink lets you run a link to a distant building.

Operator access point / fibre uplink: two SFP slots for optical modules enable a fibre link over distances from a few hundred metres to several dozen kilometres, depending on the module used.

Access layer at an integrator: a managed switch with Cisco-style CLI, STP, LACP and QoS — to slot into the customer's existing network architecture as an affordable access node with a fibre uplink.

Management like on Cisco switches — familiar CLI

DCN's command-line interface is syntactically close to Cisco IOS. An administrator familiar with Cisco devices configures the S4200-10P-SI with no extra learning — the same VLAN, trunk/access and link aggregation commands work almost identically.

Example syntax similar to Cisco IOS. You can do the same in the Web GUI without the CLI.
