Cisco Catalyst 9400 Series Switch C9404R Overview
Cisco Catalyst 9400 Series Switch C9404R is a genuine campus and data-center switching 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 Catalyst 9400 Series family, the C9404R 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 suited to access-layer and edge deployments, where reliable wiring-closet operation and straightforward management are the priorities.
From a specification standpoint, 2880 W PoE budget. 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 access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. 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 Catalyst 9400 Series 4 slot chassis”. 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.

C9404R - Deployment Notes
This C9404R switch is suited to wiring-closet, distribution, or core roles depending on the port density and uplink options of the specific model. The port configuration is a key consideration when planning power budgets for attached devices such as IP phones and access points.
For a refresh or expansion, confirm the IOS/NX-OS software release supported by this specific SKU, the fan and power requirements, and the uplink modules that match your existing infrastructure. Our team can verify revision levels and software compatibility before you order.
Every unit at LinkNewNet is inspected and tested before dispatch, and this C9404R variant is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Volume requirements can be staged with configuration checks.
C9404R - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco Catalyst or Nexus switch is typically deployed in campus access, distribution, or data-center roles. It provides reliable Layer 2/3 switching for user, server and uplink connectivity, and integrates with Cisco DNA Center or traditional CLI-based management.
Deployment guidance: When planning this C9404R 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.
