Description
Product Overview
The EtherWAN SG300-08 8-Port Hardened Smart Managed Gigabit Ethernet Switch delivers reliable Layer 2 networking for industrial automation, building infrastructure, and demanding Ethernet environments. Featuring eight 10/100/1000BASE-T RJ45 ports, it supports VLAN segmentation, Rapid Spanning Tree Protocol (RSTP), Media Redundancy Protocol (MRP), link aggregation, and multicast traffic management. Redundant 12–57V DC power inputs, fanless operation, and a hardened -40°C to +75°C temperature range make the SG300-08 suitable for installation in properly protected industrial control cabinets. Its compact DIN-rail design combines Gigabit copper connectivity with flexible network administration and monitoring.
The EtherWAN SG300-08 is an eight-port hardened Layer 2 smart managed Gigabit Ethernet switch in the EtherWAN SmartE Series. It provides eight 10/100/1000BASE-T RJ45 interfaces without SFP fiber ports or Power over Ethernet output. Management features include HTTP/HTTPS web GUI, Telnet/SSH command-line access, and SNMP v1/v2c/v3. Layer 2 functions include IEEE 802.1Q VLANs with up to 32 entries, IEEE 802.1w RSTP, IEC 62439-2 MRP manager/client operation, IEEE 802.3ad LACP, IGMP snooping v1/v2, and IEEE 802.1p QoS. The SG300-08 supports redundant 12–57V DC power inputs and consumes a maximum of 8.55W. Its fanless IP30 metal enclosure measures 45 × 130 × 125.5 mm (W × H × D), weighs approximately 388 g, and supports DIN-rail mounting with optional panel-mount accessories. Operating temperature is -40°C to +75°C. EtherWAN specifies a three-year manufacturer warranty, subject to applicable terms. Product availability and regional distribution should be confirmed before ordering.
Eight Gigabit RJ45 Ethernet Ports
The SG300-08 provides eight 10/100/1000BASE-T copper Ethernet ports for connecting compatible industrial computers, controllers, monitoring systems, and networking equipment. Auto-negotiation supports appropriate link speed and duplex settings, while auto MDI/MDIX simplifies cable installation. All ports provide Ethernet data connectivity without integrated PoE output. This model does not include SFP fiber interfaces, making it suitable for copper-focused industrial network deployments.
Layer 2 VLAN Segmentation and Traffic Prioritization
IEEE 802.1Q tagged VLAN support enables administrators to separate network traffic between connected devices and applications. The SmartE Series supports up to 32 VLAN entries for structured industrial edge networks. IEEE 802.1p and DSCP traffic classification provide Quality of Service (QoS) capabilities through eight priority queues per port. Weighted Round Robin and strict-priority scheduling allow suitable traffic to receive differentiated handling according to network requirements.
RSTP, MRP, and Link Aggregation
IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) helps prevent Ethernet switching loops and supports appropriately configured redundant network paths. IEC 62439-2 Media Redundancy Protocol (MRP) provides manager and client functionality for compatible industrial network topologies. Additional redundancy features include Large Tree Support and Fast Ring Detection. IEEE 802.3ad LACP and static trunking provide link aggregation options when supported by connected networking equipment.
IGMP Snooping and Network Access Security
IGMP snooping v1/v2 helps control multicast forwarding for compatible industrial monitoring, building automation, and IP infrastructure applications. Security functions include IEEE 802.1x network access control, RADIUS authentication, MAC address filtering, and port enable or disable settings. Storm control and system logging provide additional tools for maintaining network stability. Together, these features support controlled traffic distribution and more structured administration than an unmanaged Ethernet switch.
Web GUI, SSH, CLI, and SNMP Management
The SG300-08 supports web-based configuration through HTTP or HTTPS, command-line management through Telnet or SSH, and SNMP v1/v2c/v3 monitoring. Available administration functions include configuration backup, firmware upgrades, port mirroring, RMON, SNTP synchronization, LLDP, and system logging. A front-panel mode button supports selected IP configuration, reset, and unmanaged operating functions. These management options help technicians configure and monitor switches without requiring continuous physical access to the equipment cabinet.
Redundant DC Power and Hardened Fanless Construction
Two 12–57V DC power input connections support redundant power-source configurations, with a maximum switch consumption of 8.55W. The fanless IP30 metal housing operates from -40°C to +75°C and supports compact DIN-rail installation. Its dimensions of 45 × 130 × 125.5 mm and weight of approximately 388 g suit compatible industrial control cabinets. The IP30 rating does not provide waterproof protection, so exposed environments require an appropriately rated enclosure and proper electrical grounding.

What is the EtherWAN SG300-08 used for?
The EtherWAN SG300-08 is an eight-port hardened Layer 2 smart managed Gigabit Ethernet switch designed for compatible industrial automation, building infrastructure, and managed IP networking environments. It provides eight copper RJ45 connections along with VLAN segmentation, network redundancy protocols, Quality of Service, and remote administration capabilities.
Does the SG300-08 provide PoE power or SFP fiber ports?
No. The SG300-08 features eight 10/100/1000BASE-T RJ45 ports without integrated Power over Ethernet output or SFP fiber slots. Connected devices requiring PoE must use an independent compatible power source. Projects requiring fiber uplinks can consider the separate EtherWAN SG300-0602, which provides six Gigabit RJ45 ports and two 100/1000BASE SFP interfaces.
Does the SG300-08 support VLANs, RSTP, and MRP?
Yes. The SG300-08 supports IEEE 802.1Q tagged VLANs with up to 32 entries, IEEE 802.1w Rapid Spanning Tree Protocol, and IEC 62439-2 Media Redundancy Protocol manager/client functionality. These features allow network administrators to configure segmentation and redundancy for compatible industrial network topologies.
How can the SG300-08 be configured and monitored?
Management is available through HTTP/HTTPS web GUI, Telnet or SSH command-line access, and SNMP v1/v2c/v3. Other functions include configuration backup, firmware upgrades, port mirroring, RMON, LLDP, system logging, and SNTP synchronization. The front-panel mode button also provides selected reset and IP configuration functions.
What DC power supply does the EtherWAN SG300-08 require?
The SG300-08 accepts 12–57V DC through its terminal block and supports two redundant power input connections. Only one suitable power input is required for normal operation, while a second compatible supply can provide power redundancy. Maximum switch power consumption is 8.55W. Select an appropriately rated external DC supply and follow EtherWAN's installation, wiring, and grounding instructions.
Can the SG300-08 operate in outdoor equipment cabinets?
The SG300-08 operates from -40°C to +75°C and is suitable for compatible industrial installations with demanding temperature conditions. However, its IP30 metal housing is not waterproof or intended for direct weather exposure. Outdoor deployments require an appropriately rated protective cabinet, correct grounding, and suitable environmental controls.
What is the difference between EtherWAN SG300-08 and SG300-0602?
The SG300-08 has eight Gigabit RJ45 copper ports without SFP interfaces. The SG300-0602 provides six Gigabit RJ45 ports and two 100/1000BASE SFP slots for compatible fiber uplinks. Both are SmartE Series hardened Layer 2 managed switches supporting VLANs, RSTP, MRP, redundant 12–57V DC inputs, and operation from -40°C to +75°C. Neither provides integrated PoE output.
