Siemens RUGGEDCOM RS900G-HI-D-2SFP Managed Ethernet Switch

Product Description

Configured for Layer 2 Ethernet switching in the Siemens RUGGEDCOM RS900G network, the Siemens RUGGEDCOM RS900G-HI-D-2SFP provides eight 10/100Base-TX copper interfaces and two Gigabit SFP interfaces for industrial network communication. The switch uses store-and-forward switching and supports managed Ethernet functions for industrial network segmentation and redundancy.

Hardware Specifications

Industrial Ethernet and Network Communication

The RUGGEDCOM RS900G-HI-D-2SFP provides eight copper Ethernet ports for 10/100 Mbps field connections. In addition, two Gigabit SFP slots accept compatible pluggable optical transceivers.

The switch processes Ethernet frames using store-and-forward operation. Therefore, each frame passes through the switching process before transmission to the selected port. The non-blocking architecture supports wire-speed forwarding across the available interfaces.

For network redundancy, the switch supports eRSTP, RSTP, STP, and MSTP. It also provides IGMP Snooping for managed multicast traffic handling. Management access includes SNMP, HTTP/HTTPS, SSH, Telnet, TFTP, and SFTP, while RADIUS, TACACS+, and IEEE 802.1X provide network access-control functions.

As a Siemens industrial control component, the RS900G platform can interface with Ethernet-based PLC and industrial control networks. The supplied data does not specify Profinet certification or deterministic Profinet performance for this exact RUGGEDCOM RS900G-HI-D-2SFP model, so these functions should not be assumed from the Siemens brand alone.

Frequently Asked Questions

Q: What physical Ethernet interfaces does the RUGGEDCOM RS900G-HI-D-2SFP provide?
A: It provides 8 x 10/100Base-TX RJ45 copper ports and 2 x Gigabit SFP slots.

Q: What power input range does this model support?
A: The supplied specification identifies 88-300 VDC or 85-264 VAC high-voltage input.

Q: Does the switch require a cooling fan?
A: No. The supplied data specifies fanless, passive cooling.

Field Installation Guidelines

• Install the switch on the specified DIN rail and verify that the enclosure remains mechanically secured.
• Maintain adequate clearance around the enclosure for wiring access and passive heat dissipation.
• Route Ethernet communication cables separately from high-current power wiring where practical to reduce electromagnetic coupling.
• Use compatible SFP transceivers and fiber cables for the required Gigabit optical connection.
• Keep copper Ethernet cable routing away from high-voltage switching conductors and strong electromagnetic noise sources.
• Bond the equipment enclosure and protective grounding system according to the applicable installation standard.
• Terminate cable shields according to the plant grounding architecture and the requirements of the connected equipment.
• Verify the AC/DC supply range before energizing the switch.
• Check RJ45 and SFP connections before commissioning. Confirm link status and network redundancy behavior after power-up.
• Do not infer a specific hot-swap procedure, backplane current limit, or firmware compatibility requirement unless the applicable Siemens documentation confirms it for this exact model.
