EX3400-48P - Juniper EX3400 Series Ethernet Switches Overview
EX3400-48P - Juniper EX3400 Series Ethernet Switches is a genuine campus and data-center switching product from Juniper, a vendor known for scalable, high-performance networking platforms from the campus edge to the core. Belonging to the Juniper EX3400 Series family, the EX3400-48P unit is built to the original factory specification, so it integrates with existing Juniper 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, it offers 48 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 Juniper 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. 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.
