Deploy Hirschmann SPIDER-SL-20-04T1S29999SY9HHHH for Compact DIN-Rail Ethernet Connectivity with Four RJ45 Ports and a Long-Distance Single-Mode Fiber Link

Hirschmann SPIDER-SL-20-04T1S29999SY9HHHH is a fanless unmanaged Fast Ethernet switch for simple industrial network extensions. It combines four 10/100BASE-TX copper ports with one 100BASE-FX single-mode fiber port using an SC connection, providing a practical link between local field devices and a remote control or network cabinet.

Port and installation profile

• Four 10/100BASE-TX RJ45 ports with auto-negotiation and auto-crossing.

• One 100BASE-FX single-mode SC fiber port with distance support up to 30 km under specified link conditions.

• DIN-rail mounting, fanless construction and compact 26 × 102 × 79 mm housing.

• 12/24 V DC operation, IP30 protection and 0 to +60 °C operating temperature range.

Check the optical link before ordering

Confirm single-mode 9/125 µm fiber, SC connectors, attenuation budget and the optical interface at the remote end. The device is unmanaged, so network design should provide the required redundancy, traffic segmentation and diagnostics elsewhere in the system.

Commissioning focus

Verify power polarity and grounding, label every copper and fiber connection, and confirm link, speed and data activity LEDs after startup. Record the complete model and Belden item number 942132009 for future replacement planning.

Plan the copper and fiber network before installation

Document every connected device, port speed, cable type and destination before commissioning. Copper links should remain within the permitted channel length, while the single-mode fiber path must be checked for connector type, wavelength compatibility and total optical loss. Because this SPIDER-SL model is unmanaged, VLAN, ring recovery and managed diagnostics must be provided by other network equipment when the application requires them.

Maintenance details that reduce replacement time

Record the switch order code, cabinet location, power source and fiber route in the network drawing. Keep the RJ45 and SC interfaces clean, provide suitable strain relief, and leave service access around the DIN-rail installation. During preventive maintenance, inspect power terminals, link indicators, fiber cleanliness and cabinet temperature rather than waiting for intermittent communication faults.
