Managed PoE+ Switch 24 Gigabit Ports + 4x SFP, 370 W – DCN S4600-28P-P-SI-R3.5

DCN S4600-28P-P-SI-R3.5 — 24 Gigabit PoE+ ports with a 370 W budget for powering cameras and access points

The DCN S4600-28P-P-SI-R3.5 is a managed L2+ access switch with 24 Gigabit RJ45 PoE+ ports and 4 SFP slots for optical modules for the uplink. The 370 W PoE budget (IEEE 802.3af/at) powers IP cameras, Wi-Fi access points and VoIP phones directly over twisted pair, and the 56 Gbps fabric with 41.66 Mpps throughput ensures full throughput on all ports at once. A device for surveillance installers, network integrators and administrators who need reliable access with PoE power and a fibre uplink in a 1U chassis.

How many devices does the 370 W budget power?

The 370 W budget really means about 25-40 IP cameras (a typical 802.3af dome camera draws about 6-9 W, an 802.3at PTZ camera up to 25-30 W) or about 20-25 Wi-Fi access points (an 802.3at AP draws about 15-18 W). The switch supports PoE on all 24 copper ports — with typical surveillance cameras you power the complete set of devices without an extra power supply or injector. The IEEE 802.3af (up to 15.4 W/port) and 802.3at PoE+ (up to 30 W/port) standards adapt the power automatically to the connected load.

Proven manufacturer, support in Europe

DCN (Digital China Networks) is a switch manufacturer with long experience in carrier and enterprise networks. Distribution and support in Europe are handled by DCN Europe — a branch belonging to the Salumanus group, owner of the Fibermarkt store. This means a warranty handled within the EU, technical support with no language barrier and fast access to parts and optical modules. The device is fully compliant with the IEEE 802.3 (Ethernet), IEEE 802.3af/at (PoE/PoE+) and IEEE 802.1Q (VLAN) standards, so it interoperates seamlessly with other manufacturers' equipment.

Key features

• 24× Gigabit RJ45 PoE+ — full gigabit on every copper port with 802.3af/at power up to 30 W per port.
• 4× SFP for optical modules — 100/1000Base-X uplinks for aggregation and fibre links between cabinets.
• 370 W PoE budget — powers a complete set of IP cameras or access points without separate power supplies.
• 56 Gbps fabric, 41.66 Mpps — non-blocking throughput on all ports at once.
• 16K MAC table — support for a large number of end devices in the access segment.
• VLAN IEEE 802.1Q — traffic separation (surveillance, office, VoIP, guests) in one infrastructure.
• Link Aggregation (LACP) — bundling ports into groups for higher throughput and uplink redundancy.
• 1.5 MB packet buffer, jumbo frames 12K — stable transfer of large video streams and backups.
• L2 security — Port Security, ACL, protection against layer-2 attacks, broadcast control.
• CLI and Web GUI management — syntax close to Cisco IOS and a web configuration panel.
• 1U chassis for 19" rack — compact, ready for mounting in a server cabinet.
• 90-264 VAC power — operation across a wide mains voltage range.

Applications — for installers, integrators and administrators

IP video surveillance: power and transmission for IP cameras over a single twisted-pair cable. The 370 W budget serves several dozen cameras, and the uplinks on optical SFP modules carry the video stream to the recorder or network core.

Wi-Fi networks for businesses and hotels: central power for 802.3at access points via PoE+ removes the need for sockets at each AP. VLAN separation isolates the guest network from the corporate one.

Access layer in offices and institutions: 24 Gigabit ports for computers, printers and VoIP phones, with uplink aggregation to the core switch and full VLAN support.

Integration with the fibre network: 4 SFP slots accept single- and multimode modules and enable links between buildings and cabinets over distances unreachable for copper.

Management like on Cisco switches — familiar CLI

DCN provides a command-line interface (CLI) with syntax very close to Cisco IOS. An administrator familiar with Cisco equipment configures VLANs, trunks and link aggregation without starting from scratch — commands, configuration modes and diagnostic commands work in a familiar way. You do all this in the browser Web GUI too.

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