Hirschmann SPIDER III

Key Features

1. Three Tiers of Management:
   This is the core differentiator. The SPIDER III family is split into distinct series:

   • SPIDER III SL (Standard Line): Unmanaged switches. The direct successor to the original SPIDER, offering plug-and-play operation.

   • SPIDER III ML (Management Line): Managed switches. This is a major upgrade, bringing features like VLAN, QoS, RSTP, and ring redundancy to the compact SPIDER form factor.

   • SPIDER III RL (Routing Line): Managed Layer 3 switches. This is the most advanced tier, capable of basic IP routing (static routes), allowing communication between different IP subnets.

2. Gigabit Ethernet Performance:
   While the original SPIDER was primarily Fast Ethernet (10/100), the SPIDER III family widely introduces Gigabit (10/100/1000 Mbps) ports. Many models feature a combination of Gigabit and Fast Ethernet ports, with some offering dedicated Gigabit uplinks.

3. Enhanced Ruggedness:

   • Maintains a wide operating temperature range (typically -40 °C to +75 °C).

   • High immunity to vibrations and shocks, crucial for mobile equipment.

   • Robust EMC performance for industrial and vehicular applications.

4. Advanced Ring Redundancy:
   The managed (ML/RL) models support Hirschmann's own HIPER-Ring protocol, which offers ultra-fast network recovery times (< 50 ms). Some models also support standard protocols like MRP for compatibility with PROFINET networks.

5. Compact and Modular Design:

   • Retains the compact, space-saving design.

   • Many models offer modular power supply inputs and optional SFP slots for fiber optic uplinks, providing flexibility without increasing the base footprint.

     
     

     
     

     The Hirschmann SPIDER III family successfully transforms the simple "SPIDER" concept into a sophisticated, scalable networking solution. It is no longer just a simple unmanaged switch but a comprehensive family that can serve as the core network infrastructure for an entire piece of complex mobile equipment. If you need the smallest possible form factor without compromising on advanced networking features for a harsh environment, the SPIDER III ML and RL series are exceptional choices.
