NIM-16A - Cisco 4000 Series ISR Module Overview
NIM-16A - Cisco 4000 Series ISR Module is a genuine modular capacity expansion product from Cisco, a leading enterprise networking vendor whose Catalyst, Nexus and ISR families power campus, data-center and branch networks worldwide. Belonging to the Cisco 4000 Series family, the NIM-16A unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is deployed as a standalone unit or as part of a larger managed network, following the standard operating procedures of the platform.
From a specification standpoint, it offers 16 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include adding ports and performance to existing chassis systems, modernizing legacy platforms with compatible line cards, and mixing copper, fiber and high-speed uplinks in one chassis. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “16-Port Async Serial NIM”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.

NIM-16A - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco module/line card expands the capability of a chassis platform, adding interface density, forwarding capacity, or service features. It is installed in a matching chassis slot and managed as part of the parent platform.
Deployment guidance: When planning this NIM-16A unit into a network, confirm the software image (IOS/IOS-XE/NX-OS) required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Cisco reconditioning process: Every pre-owned Cisco unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Cisco management tools.
Related models in this family: P-LTEAP18-GL, C-NIM-1X, M2USB-16G, SM-X-8FXS/12FXO, C-SM-16P4M2X. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
Model code: A = AC power supply / Americas regulatory domain - this suffix indicates the feature set, power, or regulatory variant of the NIM-16A, which affects software licensing and regional compliance.
