Switch modules

In many companies, network expansion doesn't immediately mean replacing an entire switch. Often, adding a single component is enough – and that's where switch modules come in. They allow you to extend the functionality of network devices with additional ports, protocols, uplink features, and even support for new generation standards. Whether we're talking about stacking solutions (connecting switches into one logical system), fiber optic uplinks, or pass-throughs for blades and storage, modules are a way to scale and flexibly adapt infrastructure to current needs – without costly rebuilds or investments.

Each module has its specific use – so it's crucial to select it not only for the switch but also for the type of network traffic.

• Uplink modules, like the Cisco C3KX-SM-10G or Juniper MPC-3D-16XGE, are solutions for data centers and backbone networks. They allow you to connect server switches to main routers or other nodes at speeds up to 10/25/40GbE – with SFP/SFP+ support, hot-swapping, and QoS.
• Stacking modules, such as the Dell Force10 10HH5, are effective where horizontal scalability is key. You can connect up to eight switches into a single logical unit with redundancy and central management.
• Finally, pass-through modules, like the Dell 1KC9R or HPE 10GbE Pass-Thru, are a way to achieve maximum throughput in blade or server environments – without processing, delays, or CPU load.

Each of these types has its place – and Hardware Direct offers them all, with precise descriptions of their applications.

Hardware Direct's offering is aimed at three key groups.

• For small and medium-sized businesses, Dell PowerConnect modules (e.g., 10GbE CX4) allow you to expand an existing network without buying new hardware.
• For medium and large enterprises, models like the Dell DF10MXL (8x10GbE + 2x40GbE uplink) or Juniper MPC-3D-16XGE-SFPP-P provide throughput up to 320 Gb/s and support for AI/ML or VM-storage traffic.
• For telecommunications operators and service providers, specialized modules like the Juniper RE-S-1800X4-32G are available – for 5G or VoIP traffic aggregation, with redundancy and compatibility with carrier-grade infrastructure.

Importantly, every module is fully compliant with manufacturer documentation, covered by a 12-month warranty, available immediately, and often up to 60% cheaper than new. If you need a specific port, QSFP/SAS, or SFP+ expansion, you don't have to search blindly – here you'll find a ready-made solution, tailored to your real working environment.
