Cisco 3900 Series 3945 Integrated Service Router CISCO3945 Chassis Overview
Cisco 3900 Series 3945 Integrated Service Router CISCO3945 Chassis is a genuine edge and wide-area routing product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco 3900 Series family, the CISCO3945 Chassis 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 3 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 branch and campus WAN connectivity, service-provider edge and MPLS deployments, and secure remote-site interconnect. 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 3945 with 3 onboard GE, C3900-SPE150K9, 4 EHWIC slots, 4 DSP slots, 1 ISM slot, 4 SM slots, 256MB CF default ,1 GB DRAM default ,IP Base”. 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.

CISCO3945 Chassis - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco router is positioned at the WAN edge, branch, or service-provider aggregation point. It provides routing, VPN, QoS and security services, and integrates with Cisco IOS-XE / IOS-XR management.
Deployment guidance: When planning this CISCO3945 Chassis 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: CISCO3925, CISCO3925, CISCO 3945E/K9, CISCO3925E-K9, C3925-VSEC/K9. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
