CISCO3925E-V/K9 - Cisco 3900 Series Integrated Service Router Overview
CISCO3925E-V/K9 - Cisco 3900 Series Integrated Service Router 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 CISCO3925E-V/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, it offers 4 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 3925E Voice Bundle, PVDM3-64, UC License PAK”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
