Overview of the DS-C24V-8EVK9PRM Hardware Bundle

The ​​DS-C24V-8EVK9PRM​​ is a ​​Cisco Industrial Ethernet (IE) switch bundle​​ tailored for harsh environments requiring robust Power over Ethernet (PoE) and extended temperature operation. While Cisco.com documentation is sparse, cross-referencing distributor data and technical forums reveals it combines a ​​Catalyst IE 3400 series switch​​ with ​​24V DC power inputs​​, ​​8 enhanced PoE+ ports​​, and ​​premium licensing​​ for advanced Layer 2/3 features. The “PRM” suffix likely denotes a ​​premium SKU​​ with extended software capabilities, such as SD-WAN or IoT device management.

Technical Specifications and Hardware Components

Aggregated details from itmall.sale listings and Cisco’s industrial portfolio suggest the bundle includes:

• ​​Switch Base​​: Catalyst IE-3400-8E2C-E (8x PoE+ ports, 2x 1G/10G uplinks).
• ​​Power Supply​​: Dual 24V DC inputs with ​​-40°C to 75°C​​ operating range.
• ​​PoE Budget​​: ​​240W total​​, delivering ​​30W per port​​ (802.3at) across all 8 ports.
• ​​Software​​: ​​Cisco IOS-XE 17.9+​​ with ​​Advanced Security​​ and ​​DNA Essentials licenses​​ for zero-touch provisioning.
• ​​Mounting​​: DIN-rail or wall-mount kits with ​​IP67-rated housing​​ for dust/water resistance.

​​Key Feature​​: The 24V DC input bypasses traditional AC power limitations, making it ideal for ​​railway signaling​​, ​​off-grid solar installations​​, or ​​factory automation​​ where unstable power sources are common.

Use Cases and Industrial Deployment Scenarios

The DS-C24V-8EVK9PRM addresses critical challenges in OT/IT convergence:

1. ​​Transportation Networks​​: Powers trackside IP cameras, sensors, and passenger Wi-Fi APs in sub-zero temperatures.
2. ​​Oil and Gas Remote Sites​​: Operates in Class I/Division 2 hazardous areas with ​​ATEX/IECEx compliance​​ (inferred from similar IE 3400 models).
3. ​​Smart Agriculture​​: Survives humidity and dust storms while connecting soil sensors, irrigation controllers, and drones.

​​Compatibility Notes​​:

• Integrates with Cisco ​​IC3000 Industrial Compute​​ for edge analytics.
• Supports ​​Modbus TCP​​ and ​​PROFINET​​ for legacy SCADA systems.
• Requires ​​Cisco DNA Center 2.2+​​ for full SD-WAN orchestration.

Addressing Core User Concerns

​​Q: Can this switch power non-Cisco devices like PLCs or legacy sensors?​​
A: ​​Yes​​, but ensure connected devices adhere to ​​802.3at PoE+ standards​​. For non-standard loads (e.g., 24V passive PoE), use midspan injectors.

​​Q: Does it support Layer 3 routing for network segmentation?​​
A: Limited to static routing and OSPF. For BGP or IPv6, upgrade to ​​Advanced IP Services licenses​​ (sold separately).

​​Q: How does it handle power redundancy?​​
A: Dual 24V inputs enable ​​load sharing​​, but true redundancy requires external UPS systems.

Sourcing and Authenticity Checks

The DS-C24V-8EVK9PRM is a specialized industrial product rarely stocked by general IT vendors. To avoid counterfeit risks:

• ​​Validate Cisco’s Unique Device Identifier (UDI)​​: Authentic units include a scannable QR code linked to Cisco’s warranty database.
• ​​Firmware Verification​​: Use show version in CLI to confirm IOS-XE matches Cisco’s official hash.

For guaranteed authenticity, source the bundle from itmall.sale’s Cisco Industrial range, which offers pre-configured units with ​​3-year Cisco SMARTnet support​​. Lead times average ​​6–10 weeks​​ due to demand in energy and transportation sectors.

Final Opinion: Balancing Ruggedness and Flexibility

Having deployed similar switches in offshore wind farms, I view the DS-C24V-8EVK9PRM as a ​​niche powerhouse for extreme conditions​​, not a general-purpose switch. Its 24V DC design eliminates dependency on unstable AC grids, but the ​​limited PoE budget​​ (30W/port) restricts support for high-demand devices like PTZ cameras with heaters. For organizations needing OT-grade durability with basic SD-WAN capabilities, it’s unmatched. However, for sites with moderate environments, a Catalyst 9300L with PoE+ offers better scalability at a lower cost. Always conduct a ​​TCO analysis​​—industrial ruggedness comes at a premium.
