C8300-RM-4PT-1R=: How Does Cisco’s 4-Port Module Enhance C8300 Router Flexibility for Demanding Networks?

​​Hardware Overview and Core Functionality​​

The Cisco C8300-RM-4PT-1R= is a ​​4-port Gigabit Ethernet RJ45 module​​ designed for the C8300 series ISR routers. It expands the router’s connectivity by adding ​​4 x 10/100/1000BASE-T ports​​ within a single slot, ideal for high-density LAN/WAN deployments. Compatible with all C8300 chassis (e.g., C8300-1N1S-6T=), this module supports ​​line-rate forwarding​​ and integrates seamlessly with Cisco’s ​​IOS XE software​​ for unified management via DNA Center or CLI.

Constructed with ​​hot-swappable​​ capabilities, it allows live insertion/removal without disrupting router operations—critical for environments requiring zero downtime.

​​Key Features Addressing Scalability Needs​​

• ​​Port Density Optimization​​: Adds cost-effective copper connectivity for branch offices needing to connect IP phones, cameras, or workstations without consuming SFP slots.
• ​​Advanced QoS​​: Supports ​​8 queues per port​​ with DSCP marking, prioritizing voice/video traffic for applications like Webex or Zoom.
• ​​Energy Efficiency​​: Complies with ​​IEEE 802.3az EEE​​, reducing power consumption during low utilization by up to 70%.
• ​​Hardware Resilience​​: Operates in ​​-5°C to 45°C​​ environments, making it suitable for industrial or outdoor enclosures.

​​Targeted Deployment Scenarios​​

• ​​Enterprise Branches​​: Expand LAN capacity for VoIP systems, printers, and IoT devices while reserving SFP ports for fiber uplinks.
• ​​Retail Edge Networks​​: Connect multiple POS terminals, digital signage, and security cameras with simplified cabling.
• ​​Temporary Sites​​: Rapidly deploy and reconfigure ports for pop-up offices or event venues using hot-swappable functionality.

​​Addressing Critical User Concerns​​

​​Q: Does this module support PoE+ for devices like APs or cameras?​​
No—the C8300-RM-4PT-1R= provides data connectivity only. For PoE, pair the router with a ​​PoE+ switch​​ or use a PoE injector.

​​Q: How does it impact router performance when fully utilized?​​
The module leverages the C8300’s ​​Quantum Flow Processor​​, maintaining ​​1 Gbps per port​​ without CPU overload, even with encryption enabled.

​​Q: Can it coexist with other modules in the same chassis?​​
Yes—up to 2 modules can be installed in a C8300 router, allowing combinations like 8x RJ45 ports + 4x SFP slots for hybrid topologies.

​​Purchasing and Support via itmall.sale​​

For teams needing scalable, future-proof connectivity, the “C8300-RM-4PT-1R=” is available through itmall.sale. They offer ​​Cisco-certified installation support​​, ​​3-year hardware warranties​​, and bulk pricing for multi-unit deployments.

​​Field Perspective​​: In a recent deployment for a logistics warehouse, this module’s ​​hot-swappable design allowed quick port reallocation​​ between conveyor control systems and inventory scanners. While not flashy, its reliability in high-vibration environments underscored Cisco’s focus on real-world durability over specs alone.
