VNX+ Ethernet Switch: A Closer Look into Rugged, Modular Switches
In rugged embedded computing, your processor may be doing extraordinary work. But if the data cannot move cleanly, quickly, and reliably between modules, none of that processing matters. Networking in a VNX+ system is not just a consideration because it sits at the architectural core of how a system performs under real-world conditions.
The VNX+ Ethernet Switch, Netspyder VX, is an answer to this challenge: a compact, L2/L3 managed switch module designed to operate within the VNX+ ecosystem, serving avionics, aerospace, defense, industrial automation, and beyond. This blog allows engineers, procurement officers, and anyone who is interested in modular switches to explore the module in depth. Keep reading to learn about the VNX+ ethernet switch, its compliance with the VITA 90 standard, and its unique features.
What is the VNX+ Ethernet Switch
The Netspyder VX carries the VNX Profile designation VNX.SW-1-HH.400-7.4.1.1. That profile string encodes a great deal. It identifies the module type (switch), the half-height form factor, the 400-pin connector interface, and the VITA 90.0-2026 base standard compliance.
At its core, the Netspyder VX is a rugged Ethernet switch module delivering 8 ports of 10/100/1000 Mbps GigE, expandable to 24 ports, plus dual 10GbE SFI uplink ports. It operates as both a Layer 2 and Layer 3 managed switch. Hence, it handles everything from VLAN segmentation to dynamic IP routing in a single, compact module.
How a VNX+ Ethernet Switch Differs from a Basic Switch
| Basis | VNX+ Ethernet Switch | Basic Ethernet Switch |
| Build | Rugged build | Standard build |
| Applications | Aerospace, defense, and heavy industries | Commercial purposes, such as software companies and data centers |
| Standard Compliance | ANSI/VITA 90.0-2026 (VNX+ Base Standard) | Basic networking standard |
| Modularity | Modular, plug-in modules for easy integration | Monolithic (rigid), needs custom build for integration |
| Size and Weight | Compact size and lightweight – ideal for limited footprint | Usually large and heavy – needs more space |
Layer 2+ Switching: Building the Foundation
A) The L2 software support is comprehensive. The VNX+ switch supports up to 8K MAC addresses, enabling large network topologies. It handles 4K VLANs per the IEEE 802.1Q.
B) Traffic is also managed with support of 8K IPv4 and IPv6 multicast groups. Jumbo frames are supported at all speeds.
C) Link aggregation on the Netspyder VX is flexible, functioning across Layer 2 through Layer 4.
D) Storm control for multicast, broadcast, and flooding keeps the network from being overwhelmed by traffic
E) The Netspyder VX supports RSTP and MSTP, alongside multi-protocol compatibility for IEEE 802.1d, IEEE 802.1w, IEEE 802.1s, and IEEE 802.1x.
F) QoS on this rugged VNX+ switch provides 8 priorities with 8 QoS per port and scheduler support.
Layer 3+ Routing: Expanding the Intelligence
The reason why the Netspyder VX steps beyond a conventional managed switch is in its Layer 3 capabilities.
A) Hardware- and software-based IPv6 L3 static routing is supported, so the traffic can be directed seamlessly.
B) Dynamic routing via RFC 2328 OSPFv2 allows the Netspyder VX to adapt as per the mission, reducing network failures.
C) IEEE 1588 Precision Time Protocol (PTP) support brings high-accuracy time synchronization to the switch, avoiding the need for a separate timing module.
D) RADIUS accounting, Port and Queue policers add another layer of control, preventing any system inefficiencies.
Hardware Architecture and Connectivity
The Netspyder VX provides 8 ports (Gigabit Ethernet) using MDIO. Three QSGMII ports enable expansion, supporting either 8 or 12 additional ports via an optional expansion module. For high-speed uplinks, dual 10GbE SFI ports are available in a 400-pin interface with zero-aperture, or 320-pin MT optical interfaces with half-aperture. An RS232 console is also part of the ethernet switch. The 400-pin Searay connector routes all signals through a single interface point, which is what makes the VNX+ form factor so integration-friendly.
SWaP Specs
The Netspyder VX measures 3.5 × 3.07 × 0.75 inches, weighing approximately 0.55 lbs, with typical power consumption ranging from 15 to 20 W depending on configuration. This SWaP profile places the Netspyder VX easily within the constraints expected for embedded systems like UAVs, ground vehicles, shipboard electronics, satellite platforms, and rackmount industrial systems.
Conclusion
The Netspyder VX is a modular VNX+ ethernet switch that enables seamless networking in unreliable conditions and environments. It can slot into a VNX+ chassis alongside processor modules, I/O modules, and storage modules without requiring custom cable harnesses or external connectors. It distinguishes itself from standard switches through its rugged build, compliance with the VNX+ Base Standard, modular design, and SWaP optimization.
