Ethernet Switches – Enterprise-Grade Networking for Reliable Connectivity

Ethernet switches are a core element in modern network design, enabling fast, secure, and scalable data exchange across departments, servers, and connected devices. At GEKKO, we offer a comprehensive range of refurbished Ethernet switches for access, distribution, and data center use cases.

We carry high-quality devices from trusted brands including Cisco, HPE, Dell, Juniper, and Extreme Networks – from compact 1G PoE switches to multi-layer 100G core systems.

Layer 2 or Layer 3 – Network Control That Scales

Choose between Layer 2 switches for MAC-level switching in VLAN environments or Layer 3 models with full IP routing capabilities. Our advanced models support features like ACLs, static routes, OSPF, BGP, and VRRP – giving you full control over enterprise-grade networks.

Key Features & Interfaces

  • Port options: 1G to 100G via RJ45, SFP, SFP+, or QSFP
  • Power over Ethernet (PoE/PoE+) for VoIP, IP cameras, and Wi-Fi access points
  • Stacking options for switch clustering and unified management
  • Redundant power supplies & enterprise-grade cooling

Common Use Cases

  • Access switching for office endpoints and floor networks
  • Distribution/Core switching in medium to large enterprises
  • Industrial switches with hardened casing and temperature tolerance
  • Enterprise segmentation with QoS, VLANs, SNMP, and ACL support

Refurbished Ethernet Switches from GEKKO

Each device is professionally cleaned, tested, and firmware-updated. Our switches are ideal for IT departments looking to expand infrastructure without sacrificing performance or budget.


Ethernet Switches FAQ

Frequently Asked Questions about Ethernet Switches

What is an Ethernet switch?

An Ethernet switch is a networking device used to connect multiple devices such as PCs, servers, and printers in a Local Area Network (LAN). It operates on Layer 2 and forwards data packets intelligently to the correct port.

What's the difference between unmanaged, smart, and managed switches?

Unmanaged switches work out of the box without configuration. Smart switches offer limited management features like VLANs. Managed switches provide full control over network traffic, including SNMP, QoS, port mirroring, and advanced security features.

How many ports should an Ethernet switch have?

The number of ports depends on your needs. Small offices often use 5–8 ports, medium networks may need 16–24, and enterprise networks or data centers typically use 48 ports or more.

What does PoE (Power over Ethernet) mean?

PoE-enabled switches can deliver power and data over the same Ethernet cable. This is useful for powering devices such as IP cameras, VoIP phones, and wireless access points without separate power supplies.

What speeds do Ethernet switches support?

Common speeds include 10/100 Mbps (Fast Ethernet), 1 Gbps (Gigabit Ethernet), and 10 Gbps (10-Gigabit). High-performance switches for enterprise use support 25, 40, or even 100 Gbps using SFP/SFP+ or QSFP modules.

What is the difference between Layer 2 and Layer 3 switches?

Layer 2 switches operate on the MAC address level and connect devices within a single subnet. Layer 3 switches add routing capabilities and can forward traffic between different subnets or VLANs.

How do I choose the right switch for my application?

Consider the number of devices, desired speed (1G, 10G, etc.), PoE requirements, whether management features are needed, and if VLANs or QoS are essential. For larger or complex networks, a managed Layer 2/3 switch is recommended.

What is an industrial Ethernet switch?

Industrial switches are designed for harsh environments, offering extended temperature support, resistance to vibration and dust, and often DIN-rail mounting. They're common in automation, outdoor, and production environments.

What does VLAN mean and why is it important?

VLAN (Virtual LAN) allows logical separation of network segments within the same physical switch. It's useful for enhancing network security and performance by isolating specific types of traffic (e.g., admin, guest, VoIP).

Are refurbished Ethernet switches available with warranty?

Yes. At GEKKO Computer, you can get fully tested refurbished Ethernet switches from leading brands like Cisco, Dell, or HPE – including warranty and optional SLA service packages for professional environments.
