Cisco ASR 903 Chassis ASR-903 Overview
Cisco ASR 903 Chassis ASR-903 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 family, the ASR-903 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.
This unit follows the original factory specification for the Cisco family, covering its intended role without compatibility surprises. Standard mounting, cabling and management practices apply, and it interoperates with surrounding hardware using the same procedures as other Cisco equipment already deployed in the network.
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 ASR-903 ASR 903 Series Router 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.

ASR-903 - Deployment Notes
This ASR-903 router serves branch, edge, or WAN-aggregation roles depending on the interface mix and forwarding capacity of the specific SKU. Verify the interface types (GE, 10GE, SFP, WAN), memory, and module slots that this variant provides against your deployment topology.
When planning a refresh, confirm the software feature set (base, advanced, security) applicable to this SKU and the licensed throughput. Our team can confirm software state and hardware revision before dispatch.
Each ASR-903 unit is inspected, tested and verified before leaving our facility, including interface operation, console access, and firmware state. Contact us for volume pricing and staged delivery options.
ASR-903 - 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 ASR-903 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: ASR-920-24SZ-M, A900-IMA8S, A900-PWR-BLANK, A903-RSPA-BLANK, A901-12C-FT-D. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
