Introduction: The JHA-MIWS2G08H series is a high-performance, cost-effective, high-end intelligent gigabit managed ring network industrial-grade optical fiber switch. Support 2 10G optical ports (SFP slots) + 8 10/100/1000Base-T(X) port. It adopts the self-developed ring network technology (network failure self-healing time <20ms), users can easily set a redundant ring network to increase network reliability, and also supports CLI, SNMP, WEB, VLAN management, support Console/Telnet command line management. Rich QoS features for data flow control and management, support ring protocol, RSTP and STP Ethernet redundancy, support port-based VLAN, IEEE 802.1Q VLAN and GVRP protocol. The product also uses fanless, low power consumption, industrial-grade design, can adapt to harsh industrial environments, and has an operating temperature range of -40 to 85°C, which can meet the requirements of various industrial sites.  Specification: Interface Fiber Port 2*10G SFP+ Ethernet Port 8*10/100/1000 Base－T POE Manage Port 1*RJ45 Console port Power connector 3P Phoenix terminal, dual power supply redundancy LED Indicator PWR (green);System indicator:SYS(green);Network port indicator:yellow(1000 or POE) Green (Link) Cable type and distance Twisted pair cable 0-100m (CAT5e, CAT6) Single-mode fiber 20/40/60/80/100KM Multimode fiber 550m/2KM Optical fiber interface LC/SC Network topology & scale Ring topology Support Star topology Support Bus topology Support Tree topology Support Hybrid topology Support Electrical characteristics Input voltage DC10-58V/DC48-58V Power consumption Non-POE full load (Total power) <10WPOE full load <132W PoE Support(Optional) PoE ports 1-8 PoE protocol 802.3af, 802.3at PoE pin assignment 1,2,3,6 PoE management mode Support L2 Features Exchange capacity 64G Packet forwarding rate 47.6Mpps MAC address table 16K VLAN support and quantity Support 4K Report buffer 12M Forwarding delay <10us Port characteristics Cross-connect and direct-adaptive Flow control Support Jumbo frame support Support10Kbytes Spanning Tree Protocol Support STP/RSTP/MSTP Ring network protocol Support ERPS Link aggregation Support 12 groups Multicast Support IGMP Snooping Port mirroring Support Storm suppression Support Port traffic statistics Support Port flow system Support QINQ Support     Protection Shell: IP40 protection, aluminum alloy housingIEC 61000-4-5 Level 3 (4KV/2KV) (8/20us)IEC 61000-4-5 Level 3 (6KV/2KV) (10/700us)IEC 61000-4-3 Level 3 (10V/m)IEC 61000-4-4 Level 3 (1V/2V)IEC 61000-4-6 Level 3 (10V/m)IEC 61000-4-8 Level4 (30A/m)IEC 61000-4-11 Level3 (10V) EMI CLASS A IEC 61000-4-2 Level 4 (15KV/30KV) Free fall 0.5m Convergence Service ACL Support 500 ACLs;Support IP standard ACL;Support MAC extended ACL;Support IP extended ACL; QoS Support QoS re-marking and priority mapping;Support SP, WRR queue scheduling;Support entry speed limit and exit speed limit;Support flow-based QoS Management function Command line Support Management serial port Support Telnet Support WEB management Support SNMP Support SNMPv1/v2c User management Support System log Support File upgrade Support Firmware upgrade Support SFP module DDM Support Environmental conditions Working temperature -40℃~+85℃ Storage/transport temperature -40℃~+85℃ Relative humidity 5%~95% does not support condensation (non-condensing) Cooling method No fan design, natural heat dissipation MTBF 100,000 hours Mechanical structure Size 181X146X47mm Installation method DIN Rail Installation Weight 1KG Dimension Order Information Model No. Description of Goods JHA-MIWS2G08H Managed Industrial Ethernet Switch, 2 10G SFP+ Slot and 8 10/100/1000Base-T(X), DIN-Rail, DC10-58V, -40-85°C Operating Temperature JHA-MIWS2G08HP Managed Industrial PoE Switch, 2 10G SFP+ Slot and 8 10/100/1000Base-T(X) PoE/PoE+  DIN-Rail, DC48-58V, -40-85°C Operating Temperature Power Supply: DC24V DIN-Rail Power Supply or Power Adapter is Optional.(Non-PoE)                                        DC48V DIN-Rail Power Supply or Power Adapter is Optional.(PoE)
