Cisco Compatible ACS-2900-RM-19
19 inch rack mount kit for Cisco 2911/2921/2951 ISR
Product Highlights
When deploying Cisco 2900 Series Integrated Services Routers in a professional data center or server room environment, proper rack mounting is essential for physical security, airflow management, and efficient use of rack space. Without a proper mounting solution, routers sit loose on shelves — creating cable management headaches and airflow obstructions that can lead to overheating.
The ACS-2900-RM-19 is a Cisco compatible 19-inch rack mount kit specifically designed for the Cisco 2911, 2921, and 2951 ISR routers. This kit includes mounting brackets and the necessary screws to securely install your router into any standard 19-inch equipment rack. Constructed from durable steel, the brackets provide a stable, reliable foundation that keeps your networking equipment safely in place.
Ideal for enterprise branch offices, campus network closets, managed service provider deployments, and colocation facilities, this rack mount kit ensures your Cisco 2900 Series router is professionally installed with proper ventilation and cable accessibility. As a Cisco compatible accessory, it delivers the same precise fit at a fraction of the OEM cost — making it a smart procurement choice for IT teams managing multiple router deployments.
Features & Benefits
Precise Cisco 2900 Series Compatibility
The ACS-2900-RM-19 is purpose-built to match the chassis dimensions and screw hole patterns of the Cisco 2911, 2921, and 2951 Integrated Services Routers. This ensures a flush, secure fit without modification — saving installation time and eliminating compatibility guesswork.
Standard 19" Rack Integration
Designed for standard 19-inch (48.3 cm) equipment racks, this kit integrates seamlessly into existing rack infrastructure. Whether you're working with open-frame racks, enclosed cabinets, or wall-mount enclosures, the standard form factor ensures universal compatibility across your facilities.
Durable Steel Construction
Built from high-quality steel, these mounting brackets deliver the structural integrity needed to support Cisco 2900 Series routers over the long term. The robust construction prevents flexing or warping, keeping your equipment securely positioned even in high-vibration environments.
Optimized Airflow & Cable Management
Proper rack mounting promotes unrestricted airflow around the router chassis, which is critical for maintaining operating temperatures within spec. Organized rack placement also simplifies cable routing, reducing the risk of accidental disconnections and making maintenance faster.
Cost-Effective Cisco Compatible Alternative
As a Cisco compatible (third-party) rack mount kit, the ACS-2900-RM-19 provides the same form factor and fitment as the OEM part at a significantly lower price point. This makes it an excellent choice for budget-conscious deployments or bulk rollouts across multiple sites.
Deployment Scenarios
Enterprise Branch Office Deployment
Branch offices running Cisco 2911 or 2921 routers benefit from professional rack mounting to maintain a clean, organized network closet. The ACS-2900-RM-19 ensures the router is securely installed, simplifying on-site maintenance and reducing the risk of accidental displacement.
Data Center & Colocation Hosting
Colocation environments require standardized 19-inch rack mounting for all equipment. This kit allows Cisco 2900 Series routers to be installed alongside switches, firewalls, and servers in a uniform, space-efficient configuration that meets facility requirements.
Managed Service Provider (MSP) Multi-Site Rollouts
MSPs deploying Cisco 2951 routers across dozens of customer sites can reduce per-unit accessory costs by choosing this compatible rack mount kit. The consistent fit and included hardware streamline technician workflows and accelerate installation timelines.
Lab & Training Environments
IT training labs and certification prep environments frequently use Cisco 2900 Series routers. Rack mounting keeps lab equipment organized and accessible, and the lower cost of compatible accessories helps stretch limited lab budgets further.
