Product Overview and Functional Role
The CMICR-4PT is a Cisco modular interface card designed for high-density network environments requiring flexible port expansion. Based on Cisco’s naming conventions, the “4PT” designation suggests four copper RJ45 ports, likely supporting 1G or 10GBase-T connectivity. This card is engineered for chassis-based systems like the Cisco Catalyst 9000 or ASR series, enabling scalable uplinks or access-layer aggregation in enterprise or data center deployments.
Core Technical Specifications
- Port Configuration: 4x RJ45 ports with 10/100/1000 Mbps or 10G auto-negotiation, depending on chassis compatibility.
- Power Efficiency: Potential support for Energy Efficient Ethernet (EEE) to reduce power consumption during low traffic.
- Layer 2/3 Features: Likely integrates with Cisco IOS-XE for advanced routing, VLAN segmentation, and QoS policies.
Addressing Critical User Concerns
Is the CMICR-4PT compatible with older Cisco chassis?
No. Modular cards often require specific chassis generations (e.g., Catalyst 9400/9500). Verify compatibility via Cisco’s official matrix before purchase.
Does it support PoE+ for devices like cameras or APs?
Unlikely. Copper RJ45 ports on modular cards typically prioritize data throughput over PoE. For power delivery, consider dedicated PoE line cards.
Comparison: CMICR-4PT vs. Fiber-Optic Modules

Personal Insight: The CMICR-4PT is a pragmatic choice for enterprises expanding copper-based access layers without overhauling fiber infrastructure. Its auto-negotiation capability simplifies deployments, but prioritize fiber modules for latency-sensitive or high-growth core networks. Always cross-reference chassis compatibility lists—mismatched hardware can lead to costly downtime. For future-proofing, consider hybrid deployments balancing copper and fiber investments.
