Active Network Infrastructure

Active Network Infrastructure & Data Communications — Switches, Routers, Hubs & More

Enterprise networking gear for mission‑critical environments — available New or Tested.

This category is dedicated to active network infrastructure used to route, switch, and manage data traffic in offices, labs, factories, and data centers. You’ll find managed/unmanaged switches, routers, hubs, and related network electronics that support stable connectivity for critical systems (UPS monitoring, PDUs, servers, VoIP, security, and building automation).

Why these matter in critical environments

Uptime & visibility — stable switching/routing keeps monitoring and remote management online.
Deterministic performance — managed gear supports VLANs, QoS, and traffic control where it counts.
Clean integration — deploy alongside UPS/critical power stacks without consumer‑grade compromises.

Product Options — New vs. Tested

Option	What it means	Best for	Warranty
New	Factory‑new equipment with full warranty. Ideal when you want the newest lifecycle, lowest wear, and maximum long‑term deployment runway.	Standardization projects, long rollouts, compliance environments, new builds.	As listed by manufacturer.
Tested	Verified hardware that has been checked for core function and stability. Typical validation includes power‑on, port/link activity, basic traffic/pass‑through verification, and indicator/console health (test depth may vary by model and is described on each listing).	Cost‑sensitive builds, spares inventory, short‑lead replacements, lab environments.	(90‑Day)

What you’ll typically find in this category

Switches	Managed / unmanaged, PoE, SFP/SFP+, stackable, industrial, top‑of‑rack
Routers & Gateways	Edge routing, VPN gateways, WAN interfaces, multi‑site connectivity
Hubs & Legacy Interconnect	Support hardware for legacy systems, labs, and specialized control networks
Network Adapters & Modules	SFP optics, media converters, interface modules (where applicable)
