Network Switches.

Curvature provides new and preowned enterprise switches for your data center from leading manufacturers such as Cisco, HPE, Juniper, Arista, and more.

We specialize in 24 and 48 port PoE LAN access switches, LAN core and distribution switches, data center switches, and their components. Most products are readily available and come with a lifetime warranty.


LAN Access

Local area network (LAN) access is a combination of switches, cables, and routers. These enterprise access switches connect PCs, access points, and IP phones, usually within a single location. While some of the switches listed here are no longer sold by the OEM, Curvature still sells and supports these devices and has stock ready to ship at a moment’s notice.

Catalyst 9300, 9200, 3850, 3750, 3750E, 3750G, 3750X, 3650, 2960X, 2960XR, 2960L, 2960+, 2960
LAN Core and Distribution

Local area network (LAN) core switches are usually located at the backbone, or physical core, of a network and offer high-capacity capabilities. Distribution switches, on the other hand, collect and aggregate data from access switches and send it to core switches. When it comes to switches in the Cisco portfolio, whether they are previous generation, legacy, or current generation, Curvature has them in stock.

Catalyst 9600, 9500, 9400, 6500, 4500
Data Center

Curvature offers a wide variety of data center switches. Data center switches are scalable, which makes them great for programming and automation. They are high-performance, high-density switches created for large organizations and cloud providers that depend on virtualization. Data center switches can be used to anchor a one-tier/flat mesh or fabric architecture, a two-tier/leaf-spine architecture, layer 3, or used throughout the data center. Some of the switches listed here are no longer sold by the OEM, but we have them in stock and ready to ship to you.

Nexus 9000, 5000, 3000, 2000
Industrial Ethernet

Industrial Ethernet switches were created for extreme operating conditions, including temperatures as cold as -40C/-40F or as hot as 75C/167F, as well as shocks, earthquakes, and other natural disasters. Some of the switches listed below are no longer sold by the OEM, but we have them in stock and ready to ship to you.

5000, 4000, 3000, 2000, 1000
LAN Compact

Local area network (LAN) compact switches allow multiple devices to communicate with one another. They are smaller switches, which are designed for branch offices so you can save space in your network cabinets. Some of the switches listed below are no longer sold by the OEM, but we have them in stock and ready to ship to you.

Catalyst 3560CX, 3560CG, 2960CX, 1000

Storage area network (SAN) multilayer direct switches (MDS) have many layers of infrastructure and storage-management abilities. Due to their flexibility, highly scalable storage networks can be constructed, allowing for increased security and wired and wireless administration through a single interface (unified network). One of the many benefits of SAN MDS is the reduced cost of storage hardware.

9300, 9200, 9100
Metro Ethernet

Metro Ethernet enables multi-point connectivity of point-to-point services over a metropolitan area. Offering reliability, performance, and scalability, metro Ethernet is a great choice for manufacturers, corporations, and service providers of all sizes. Plus, its low latency allows for the safe and secure transfer of large amounts of video or data.

3800, 3600, 3400, 3000

HPE Aruba Switches

HPE Aruba Network Switches are top-tier solutions with advanced features, robust security measures, and streamlined management. These switches offer unparalleled flexibility, connectivity, intelligent automation, enhanced network performance, and efficient resource allocation. With our comprehensive portfolio and unwavering commitment to innovation, we provide organizations with reliable and future-proof networking solutions that set them apart in the industry.

Data Center: CX8400, CX8360, CX8325, CX8320, CX6400, CX6300
LAN / Campus / Access: 5400R, 3810, 2930, 2540, 2530, CX6000, CX4100i

Legacy often refers to older and possibly outdated equipment. Manufacturers often push for complete upgrades just because new equipment is available. Many companies, however, do not need an upgrade because their existing assets continue to function perfectly well.

Catalyst 8500, 6500, 6000, 4000, 3900, 3550, 3500, 2955, 2950, 2950G, 2970G, 2940, 2900, 1900

Why Curvature?

Most data centers and enterprise networks have IT infrastructure from multiple OEMs. When it’s time to refresh or upgrade, you benefit when you have an industry-leading supplier such as Curvature.

In addition, after an asset goes End of Life (EoL), End of Service Life (EoSL), or End of Sale (EoS), you still need to find the gear to keep your data center running. Curvature can source equipment long after an OEM stops manufacturing or servicing the parts.

Business Benefits

The benefits of optimizing your enterprise and data center networks with equipment from Curvature cannot be overstated:

Reduction of overall costs leads to increased return on investment (ROI) on IT infrastructure
Sourcing hard-to-find or EOSL parts
Data center managers can rest easy knowing that hardware is optimized, and service is quick and efficient
Improved performance, reliability, and scalability
Match your existing infrastructure
Free up resources and capital to reinvest in other projects that require upgraded technology
