Cisco Nexus 5000 Series Switch N5K-C5548UP-FA Overview
Cisco Nexus 5000 Series Switch N5K-C5548UP-FA is a genuine data-center switching fabric 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 Nexus 5000 Series family, the N5K-C5548UP-FA 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 built for high-density data-center and cloud environments, where low latency, high availability and consistent forwarding matter most.
This unit follows the original factory specification for the Cisco Nexus 5000 Series 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 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: “Nexus 5548UP Chassis, 32x SFP+ Port, Bundle 2 PS, 2 Fans”. 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.
