FPR4112-ASA-K9 - Cisco Firepower 4100 Series Overview
FPR4112-ASA-K9 - Cisco Firepower 4100 Series is a genuine network security and threat protection 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 Firepower 4100 Series family, the FPR4112-ASA-K9 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, aggregate capacity of 20 Gbps. 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 perimeter protection with stateful inspection, branch-office security with VPN and threat prevention, and data-center north-south traffic filtering. 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: “Cisco Firepower 4112 ASA Appliance, 1U, 2 x NetMod Bays”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

Deployment guidance: When planning this FPR4112-ASA-K9 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.
