The middle switch (EDS-508A-MM-SC) has 6 RJ45 10/100BaseTx ports and 2 100M SC fiber ports. The third switch (EDS-508A) is equipped with 8 RJ45 10/100BaseTx ports. All models include dual power inputs (PWR1, PWR2) and a fault indicator, along with MSTR/HEAD and CPLR/TAIL indicators for redundancy features.
Característiques principals:
- 8 10/100BaseTx Ethernet Ports
- Advanced Network Management: VLAN, IGMP Snooping, Port Trunking
- Traffic Management: RMON, Quality of Service (QoS)
- Industrial Design: Wide operating temperature, redundant power inputs
- Easy Deployment: DIN-rail or wall mounting options
5. Configuració
5.1 Instal·lació física
- Muntatge: Securely mount the EDS-508A on a DIN-rail or to a wall using the provided mounting kit. Ensure adequate space for ventilation and cable routing.
- Connexió d'alimentació: Connect the primary and secondary DC power sources to the terminal block on the top of the switch. The EDS-508A supports redundant power inputs for enhanced reliability. Ensure correct polarity.
- Posada a terra: Connect the grounding wire from the switch to a proper earth ground. This is crucial for electrical safety and EMI protection.
5.2 Connexió de xarxa
- Ports Ethernet: Connect your network devices (e.g., PCs, PLCs, IP cameras) to the 10/100BaseTx RJ45 ports using standard Cat5e or Cat6 Ethernet cables.
- Fiber Ports (if applicable): For models with fiber optic ports (e.g., EDS-508A-MM-ST, EDS-508A-MM-SC), connect appropriate fiber optic cables to extend network reach over longer distances.
5.3 Configuració inicial
- Encès: Apply power to the switch. The PWR1 and PWR2 LEDs should illuminate, indicating successful power-up.
- Adreça IP: The switch typically comes with a default IP address (refer to the Quick Installation Guide for the specific default IP). Connect a PC directly to one of the switch's Ethernet ports and configure your PC's IP address to be in the same subnet.
- WebGestió basada en: Obre a web browser on your PC and enter the switch's default IP address. Log in using the default username and password (consult the Quick Installation Guide).
- Configuració bàsica: Change the default IP address, username, and password for security. Configure basic network settings such as system time and SNMP.
6. Funcionament
6.1 Indicadors LED
- PWR1/PWR2: Solid green indicates power input is active.
- FALLA: Solid red indicates a system fault or power failure.
- MSTR/HEAD: Indicates the switch's role in a redundant ring topology (e.g., Turbo Ring).
- CPLR/TAIL: Indicates the switch's role in a redundant ring topology.
- LED del port: Solid green indicates a link is established. Blinking green indicates data activity.
6.2 Configuració de funcions avançades
Accedeix al web-based management interface or console port to configure the following features:
- VLAN (Xarxa d'Àrea Local Virtual): Segment your network into logical groups to improve security and performance.
- Snooping IGMP: Optimize multicast traffic delivery, preventing flooding of multicast packets to all ports.
- Port Trunking (Link Aggregation): Combineu diversos enllaços físics en un únic enllaç lògic per augmentar l'amplada de banda i la redundància.
- RMON (Remote Monitoring): Monitor network traffic and performance statistics for diagnostic purposes.
- QoS (Qualitat de servei): Prioritize critical network traffic (e.g., industrial control data, video streams) to ensure consistent performance.
- Redundancy Protocols: Configure Moxa's Turbo Ring, Turbo Chain, or other industry-standard redundancy protocols for network resilience.
