Managed Switch 48 Gigabit Ports + 4x SFP, L2+ – DCN S4600-52P-SI-R2

DCN S4600-52P-SI-R2 — 52 managed ports for dense access and aggregation

The DCN S4600-52P-SI-R2 is a managed L2+ switch with 48 Gigabit RJ45 ports and 4 SFP slots, designed for dense access in campus, office and carrier networks. The non-blocking 104 Gbps fabric and 77.4 Mpps switching capacity ensure full throughput on all ports at once. A 16,000-address MAC table, 4096 VLANs and hardware ACL lists let you segment and control the traffic of a large number of users. A device for installers, integrators and administrators who need many copper ports and fibre uplinks in a single 1U chassis.

Performance for aggregation and the network core

Four SFP slots (100/1000 Base-X) accept single- and multimode modules, building redundant uplink links to the core or neighbouring switches. The non-blocking 104 Gbps fabric and 77.4 Mpps throughput mean all 48 copper ports work at full 1 Gbps speed with no packet loss. LACP link aggregation (up to 16 groups, of 8 ports) lets you sum the uplink bandwidth and ensure path redundancy, and a 1.5 MB packet buffer and jumbo 12K frame support stabilise traffic under heavy load.

Proven manufacturer, support in Europe

DCN (Digital China Networks) is a switch and network infrastructure manufacturer with a long-standing presence in the carrier and enterprise market. The European branch DCN Europe operates within the Salumanus group — owner of the Fibermarkt store — so the warranty is handled within the EU and technical support is provided with no language barrier. The device complies with the IEEE 802.3 and IEEE 802.1Q standards, which guarantees interoperation with other manufacturers' network equipment.

Key features

• 52 ports in 1U — 48× Gigabit RJ45 (10/100/1000 Base-T) + 4× SFP (100/1000 Base-X) in a rack chassis.
• Non-blocking 104 Gbps fabric — full speed on all ports at once, 77.4 Mpps performance.
• L2+ layer with IPv4/IPv6 routing — IP interfaces on VLANs, static routing and IPv6 support.
• 4096 VLANs — full IEEE 802.1Q traffic segmentation, tagging and voice VLAN.
• 16K MAC table — support for a large number of end stations with no traffic flooding.
• LACP aggregation — up to 16 groups of 8 ports, bandwidth bundling and uplink redundancy.
• STP/RSTP/MSTP protocols — loop protection, up to 64 MSTP instances; ERPS (G.8032) and MRPP rings.
• Hardware ACL lists — up to 2304 traffic filtering rules based on L2/L3/L4.
• Access security — 802.1X, DHCP Snooping, IP Source Guard, dynamic ARP inspection.
• QoS with 8 queues per port — CoS/DSCP classification, prioritisation of voice and video traffic.
• IGMP Snooping v1/v2/v3 and MVR — efficient multicast distribution (IPTV, surveillance).
• CLI, Web, SNMP management — Cisco IOS-style console, HTTP/HTTPS, SNMP v2c/v3, SSH, Telnet.

Applications — for installers, integrators and administrators

Access in office and campus: 48 Gigabit ports serve a whole floor of workstations, printers and access points, and four SFP serve as fibre uplinks to the server room.

Aggregation of access switches: redundant SFP links and LACP aggregation let you build an intermediate layer that collects the traffic of many smaller switches in the distribution cabinet.

Carrier and MAN networks: segmentation of customers via VLAN, ACL lists, DHCP Snooping and IP Source Guard isolate subscribers and protect the operator's network from abuse.

Surveillance and multicast: IGMP Snooping and MVR efficiently distribute IPTV streams and the signal from IP cameras, limiting unnecessary multicast traffic in the access segments.

Management like on Cisco switches — familiar CLI

DCN provides a CLI console in the Cisco IOS style. An administrator familiar with Cisco equipment configures the S4600-52P-SI-R2 without learning a new syntax — the same commands for VLANs, trunk/access ports and link aggregation work almost identically.

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