HSGQ-3308M is an L2+ managed switch with 4*10M/ 100M/1000M RJ45 ports, 4*SFP gigabit fiber optic module slots, 1*Type-C console management interface. It supports static routing, provides comprehensive security policies, robust QoS policies, and rich VLAN functionality, making it easy to manage and maintain, and meeting the networking access needs of enterprises, residential communities, hotels, office networks, and campus networks.
4*GE+4*SFP L2+ Managed Switch
This optical-electrical integrated device is a full-Gigabit product. It features dual power supply redundancy, with optional support for an RTC (Real-Time Clock) and a temperature sensor. It supports the MQTT protocol for connectivity with the EMIS cloud management platform and is equipped with a Type-C console port. The device supports IPv4/IPv6 dual-stack, static routing, STP/RSTP/MSTP, loop detection, EPRS, and DDM (Digital Diagnostic Monitoring).
Equipped with multiple Gigabit SFP slots, the device supports transmission distances ranging from 550 meters up to 2 km (using multi-mode fiber), or extending to 10, 20, 40, 60, 80, or 120 km (using single-mode fiber), enabling long-distance data transmission to backbone switches and monitoring centers.
The product features a metal enclosure and supports both desktop and rack-mount installation. Thanks to its fanless design and optimized power output, it delivers quiet, efficient operation—ensuring consistent performance regardless of the deployment environment.
It supports DDM (Digital Diagnostic Monitor) function, which helps network administrator easily monitor real-time parameters of SFP and SFP+ optical modules, including supply voltage, bias current, temperature, optical input power, and optical output power.
Supports IPv4/IPv6 dual-stack, static routing, DHCP Server, DHCP Snooping, IGMP Snooping, STP/RSTP/MSTP, ERPS, Jumbo Frames, Loop Detection, LLDP, LACP, ACL , SNMPv1/v2c/v3, and MQTT.
Equipped with loop detection and an automatic resolution mechanism, the system enables intelligent network self-healing:
1. When a loop is detected in the network, the affected port is automatically blocked to prevent a broadcast storm from causing a total network collapse.
2. Once the loop is resolved, the port automatically transitions from the blocked state back to its normal operating state, restoring standard communication.
Redundancy Protection: Supports hardware and software redundancy, including redundant power supplies and redundant link protection, to ensure uninterrupted service.
Link Aggregation: Increases bandwidth, enhances reliability, and provides load balancing.
1. Built-in MQTT functional module.
2. Supports MQTT/SNMP protocols for connecting to the EDMS cloud management platform, enabling centralized remote device management.
3. Cloud platform supports both on-premises and cloud-based deployment.
