Core Function of the A900-DCAP-RJ45-L=

The ​​Cisco A900-DCAP-RJ45-L=​​ is a ​​hardened Ethernet port module​​ designed for Cisco Catalyst IR1100 and IC3000 industrial routers. It extends wired connectivity in harsh environments by providing ​​IP67-rated RJ45 ports​​ resistant to dust, moisture, and vibration. This module is essential for connecting legacy industrial devices (PLCs, sensors) to modern IP networks in settings like oil rigs, factories, or transportation hubs.

Technical Specifications and Use Cases

• ​​Port Configuration​​: 4x 10/100/1000BASE-T ports with ​​IEEE 802.3at PoE+​​ support (30W per port).
• ​​Environmental Durability​​: Operates in ​​-40°C to 75°C​​ and withstands 50G shock/5Grms vibration.
• ​​Compatibility​​: Requires IR1100-K9 or IC3000-K9 chassis with ​​IOS-XE 17.9+ firmware​​.
• ​​Safety Certifications​​: UL 61010-1, ATEX Zone 2, and IECEx compliance for hazardous locations.

Addressing Critical Deployment Challenges

​​Q: Can it power non-Cisco PoE devices?​​
A: Yes—the module adheres to ​​standard 802.3at PoE+​​, supporting third-party cameras, sensors, and VoIP phones.

​​Q: Is shielded cabling mandatory?​​
A: In high-EMI environments (e.g., near motors), ​​Cat6A STP cables​​ are required to prevent data corruption.

​​Q: How does it handle cable strain?​​
A: Integrated ​​M12-X-coded screw locks​​ secure connectors, preventing accidental disconnections in mobile installations.

Sourcing Certified Industrial Modules

For guaranteed performance in extreme conditions, the A900-DCAP-RJ45-L= is available exclusively via itmall.sale’s Cisco industrial portfolio. Counterfeit modules often lack proper EMI shielding, risking network instability.

Operational Realities

In a recent wastewater treatment deployment, standard RJ45 ports corroded within months, while the A900-DCAP-RJ45-L= maintained connectivity despite constant chemical exposure. This module isn’t just a “port add-on”—it’s ​​mission-critical infrastructure​​ for industries where network uptime equals operational safety. While its cost may seem high compared to commercial-grade parts, the alternative—frequent maintenance or production halts—proves far more expensive. For engineers bridging IT/OT divides, this module is the unsung hero of industrial IoT reliability.
