Cisco Compatible ACS-1861-RM-19
Rackmount Kit for 1861
Product Highlights
When deploying a Cisco 1861 Integrated Services Router in a structured cabling environment, a proper rackmount solution is essential for physical security, airflow management, and clean cable routing. Without rack ears, routers end up on shelves or stacked haphazardly — creating maintenance headaches and potential points of failure.
The ACS-1861-RM-19 is a Cisco compatible 19-inch rackmount bracket kit designed specifically for the Cisco 1861 ISR. It enables secure, professional installation of the 1861 router into any standard 19-inch equipment rack or cabinet at a 1RU height. The brackets attach directly to the chassis and align with standard rack rail hole spacing, ensuring a clean, stable mount.
This kit is an ideal solution for IT teams maintaining existing Cisco 1861 deployments in branch offices, small business environments, or lab setups. Whether you're replacing lost or damaged original rack ears or outfitting a newly acquired unit, the ACS-1861-RM-19 delivers a cost-effective, reliable mounting solution that keeps your infrastructure organized and accessible.
Note: The Cisco 1861 Integrated Services Router (C1800 series) has reached End-of-Life status. This rackmount kit is intended to support existing deployments still in service.
Features & Benefits
Standard 19-Inch Rack Compatibility
The ACS-1861-RM-19 brackets are designed for standard 19-inch equipment racks and cabinets. This ensures your Cisco 1861 router integrates seamlessly into existing rack infrastructure without adapters or modifications, keeping your data closet or server room organized and professional.
Purpose-Built Fit for Cisco 1861
These brackets are engineered specifically for the Cisco 1861 Integrated Services Router chassis. The screw hole alignment and bracket geometry match the 1861's form factor precisely, ensuring a secure and stable mount that won't shift or vibrate loose over time.
Space-Efficient 1RU Design
Occupying just one rack unit (1RU) of vertical space, this kit maximizes your available rack real estate. In dense deployments where every unit of rack space counts, a proper 1RU mount keeps your infrastructure compact and well-ventilated.
Cost-Effective Cisco Compatible Solution
As a Cisco compatible aftermarket kit, the ACS-1861-RM-19 delivers the same fit and function as the original Cisco-branded ACS-1861-RM-19= at a fraction of the cost. This is especially valuable for EOL platforms where minimizing ongoing investment is a priority.
Deployment Scenarios
Branch Office Router Deployment
Small and medium branch offices running the Cisco 1861 ISR benefit from a clean rack-mounted installation. The ACS-1861-RM-19 ensures the router is securely housed alongside switches, patch panels, and UPS units in a standard network cabinet.
Lab and Test Environments
Network engineers and CCNA/CCNP candidates maintaining home labs or training environments with Cisco 1861 routers can use this kit to organize their rack setups professionally, improving accessibility and airflow during extended lab sessions.
Replacement for Lost or Damaged Rack Ears
It's common for rack ears to be separated from routers during moves, decommissions, or resale. The ACS-1861-RM-19 provides an affordable replacement so you can get your Cisco 1861 back into the rack without sourcing hard-to-find OEM parts for an EOL platform.
