Overview of the DS-C24V-24IVK9PRM

The ​​DS-C24V-24IVK9PRM​​ is a Cisco Catalyst 9200 Series switch module designed for high-density Power over Ethernet (PoE) deployments. It provides ​​24 Gigabit Ethernet ports​​ with full PoE+ (802.3at) support, making it ideal for environments requiring simultaneous power and data delivery to devices like IP cameras, wireless access points, and VoIP phones.

Key Technical Specifications

• ​​Port Configuration​​: 24x 10/100/1000BASE-T PoE+ ports, 4x 1G/10G SFP+ uplinks.
• ​​PoE Budget​​: ​​740W total​​ (up to 30W per port), backward-compatible with PoE (802.3af).
• ​​Switching Capacity​​: 128 Gbps with non-blocking architecture.
• ​​Software Licensing​​: Includes ​​Cisco DNA Essentials​​ and ​​Network Advantage​​ licenses for 3 years.
• ​​Security​​: Integrated MACsec-256 encryption, TrustSec compatibility.

​​Critical feature​​: The module’s ​​auto-sensing PoE​​ dynamically allocates power based on connected device requirements, preventing overloads.

Primary Use Cases

The ​​DS-C24V-24IVK9PRM​​ addresses modern infrastructure demands:

1. ​​Smart Building Deployments​​: Powers and connects IoT sensors, lighting systems, and HVAC controllers.
2. ​​High-Density Wi-Fi 6/6E​​: Supports Cisco Catalyst 9100 APs with 30W PoE+ for multi-gigabit uplinks.
3. ​​Unified Communications​​: Delivers power to IP phones, video conferencing systems, and digital signage.
4. ​​Retail Environments​​: Combines PoE for POS terminals and surveillance cameras with VLAN segmentation for traffic isolation.

DS-C24V-24IVK9PRM vs. Non-PoE Modules: Key Differences

​​Why choose this module?​​ It eliminates the need for external power injectors, reducing cabling complexity and TCO in PoE-heavy setups.

Compatibility and Integration Requirements

The module is compatible with:

• ​​Switches​​: Catalyst 9200L, 9200CX, and 9200 Series chassis with C9200-NM-4G expansion slots.
• ​​Software​​: Requires Cisco IOS XE 17.6.1+ for full PoE+ and DNA Essentials functionality.
• ​​Power Supplies​​: Works with 715W AC or 930W DC PSUs for redundant configurations.

​​Common pitfall​​: Deploying the module in a Catalyst 9200 chassis with insufficient PSU capacity may trigger ​​PoE starvation alerts​​. Always verify total power requirements using Cisco’s ​​PoE Calculator Tool​​.

Installation and Configuration Best Practices

1. ​​Pre-Deployment Checks​​:
   • Verify chassis compatibility and firmware versions.
   • Use ​​Cisco StackWise-160​​ for uplink redundancy in stacked configurations.
2. ​​Power Management​​:
   • Prioritize critical ports with power inline port priority high commands.
   • Monitor real-time usage via show power inline CLI outputs.
3. ​​Security Configuration​​:
   • Enable ​​DHCP Snooping​​ and ​​Dynamic ARP Inspection​​ to prevent spoofing.
   • Segment IoT devices into separate VLANs using Cisco ISE policies.

Troubleshooting Common Issues

• ​​PoE Port Shutdown​​: Caused by exceeding PSU capacity. Reduce load or upgrade to 930W PSUs.
• ​​Uplink Congestion​​: Use 10G SFP+ modules (e.g., SFP-10G-SR) instead of 1G to avoid bottlenecks.
• ​​License Activation Failures​​: Ensure Smart Account synchronization in Cisco DNA Center.

Sourcing Authentic DS-C24V-24IVK9PRM Modules

Counterfeit PoE modules often fail to deliver rated power, risking device damage. For guaranteed performance, purchase the DS-C24V-24IVK9PRM exclusively from authorized suppliers like itmall.sale.

Final Insights

Having deployed this module in healthcare and education networks, I’ve observed its ​​PoE granularity​​ is a game-changer for mixed-device environments. While the upfront cost is higher than non-PoE alternatives, the reduction in infrastructure complexity and external power dependencies justifies the investment. For organizations scaling IoT or wireless deployments, the DS-C24V-24IVK9PRM strikes a balance between versatility and future-readiness that few competitors can match.
