RUGGEDCOM RS Series: Compact Ethernet Layer 2 Switches

Why RUGGEDCOM RS Series compact switches?

The Siemens RUGGEDCOM RS Series portfolio—RS900, RS900G, RS910, RS900GP—delivers compact, utility‑grade Layer 2 Ethernet switches for harsh industrial environments.

Extreme reliability: Substation‑hardened for −40 to +85 °C, high EMI, and shock
Flexible connectivity: Fast or Gigabit Ethernet, fiber uplinks, PoE variants
Easy integration: DIN‑rail mounting and universal AC/DC power
Secure networking: ROS with VLAN, RADIUS, SSH/SSL, SNMPv3
Resilient design: PRP/HSR support for zero‑second failover
Durable, scalable, and secure—ideal for demanding OT networks.

Key benefits

Enable reliable control in harsh conditions

Substation‑hardened design resists EMI, vibration and extreme temperatures to keep Layer 2 traffic error free for mission‑critical automation.

Simplify integration across OT cabinets

Compact form factor, DIN‑rail mounting, universal AC/DC power and long‑haul fiber options fit tight spaces and complex topologies without redesign.

Strengthen security at the network edge

ROS features add multi‑level passwords, SSH/SSL, VLAN segmentation, RADIUS and SNMPv3 to harden access and isolate traffic from non‑critical devices.

Featured capabilities

Support redundant topologies with PRP/HSR

Selected models enable zero‑second failover using Parallel Redundancy Protocol and High‑availability Seamless Redundancy for fault‑tolerant operation.

Scale bandwidth with Gigabit uplinks

Variants such as RS900G add 1000BASE‑X SFP uplinks for high‑speed backbones and long‑distance fiber runs in demanding environments.

Power field devices with high power PoE

RS900GP delivers IEEE 802.3af/at PoE ports to simplify cabling while powering cameras and controllers from a single compact switch.
