Cisco SM-X-NIM-ADPTR=

Overview

The Cisco SM-X-NIM-ADPTR= is a plug-in adapter designed to expand the capabilities of Cisco 4300 and 4400 Series Integrated Services Routers by converting the SM-X service module slot into a Network Interface Module (NIM) slot. This adapter allows a single router to access a wide range of NIM cards, enabling the addition of T1 or E1 circuits, voice ports, switching capacity, serial connectivity, or storage modules without the need for a separate chassis. Weighing approximately 2.78 pounds, it offers a flexible and efficient solution for branch offices, retail locations, and remote sites that require scalable network access.

Key features

• Supports a broad selection of NIM cards including T1/E1, FXO/FXS voice ports, switching, serial, and storage modules
• Maintains full line-rate throughput for T1 and E1 circuits, ensuring consistent network performance
• Plug-in design allows for quick installation with captive screws, minimizing downtime and setup complexity
• Automatically recognized by the router’s IOS interface for immediate configuration after installation
• Lightweight construction reduces additional weight and thermal load on the router chassis
• Compatible with Cisco ISR 4321, 4331, 4351, and 4431 models, providing broad applicability within the 4000 Series

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
