A switch is a device in a computer network that electrically and logically connects together other devices. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received message only to the one or more devices for which the message was intended. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. This maximizes the security and efficiency of the network.
Essentially, when replacing a repeater hub with an Ethernet switch, the single large collision domain is split up into smaller ones, reducing the probability and scope of collisions and, as a result, increasing the potential throughput. Because broadcasts are still being forwarded to all connected devices, the newly formed network segment continues to be a broadcast domain.

Due to these features, a switch may be seen as more "intelligent" than a repeater hub, which simply retransmits messages out of every port of the hub but the receiving one, unable to distinguish different recipients, and greatly degrading the overall efficiency of the network.
ubiQuoss provides a full line of powerful, business-class ethernet switching solutions for all your network needs. Perfect for SMB and multi-site enterprise networks, ubiQuoss Ethernet Switches address today’s highest networking priorities from bandwidth expansion and VoIP migration, to network security. Choose from managed Core/edge, Aggregation, Access Switch product lines. Our ethernet switches are differentiated by their security, ease-of-use, and management features like MAC-based port security and cable diagnostics.


Core/Edge Switches 


The ubiQuoss Core/edge switches simplify the architecture for Enterprise IT managers have limited time or resources to deal with overly complex, specialized network infrastructure solutions. Purpose-built core, aggregation, edge and Data Center modules can meet the chassis needs across network. Traditional three-tier architectures can be replaced with a streamlined two-tier network that reduces management overhead, operational complexity and capital expenditures.

The ubiQuoss Core/edge switches deliver voice-class availability, Gigabit Ethernet, and 10 Gigabit Ethernet wherever it’s needed. They serve well as a high-performance Enterprise core. The non-blocking ports interconnect thousands of servers for High Performance Cluster Computing (HPCC) and data center applications. A full range of Layers 2 and Layer 3 features for IPv4 and IPv6 allow the aggregation of high-speed connections, eliminating bottlenecks between edge and core. ubiQuoss Core/edge switches fit well at the edge of the most demanding enterprises switching Voice-over-IP (VoIP), video, wireless and data traffic.


Aggregation Switches(Layer3) 


Within the LAN environment, a Layer 3 aggregation switch makes intelligent switching decisions based on the Layer 3 source and destination addresses, similar to that of a router. A standard Layer 2 switch relies on the MAC addresses to make switching decision. The fundamental difference between the two, is that a Layer 3 aggregation switch offers more performance compared to a standard Layer 2 switch.
The ubiQuoss Layer 3 aggregation switches combine performance, reliability and security. These switches are perfect for Gigabit to the desktop applications or as an aggregator switch routing between VLANs, therefore segmenting data and voice and offering additional security.


Access Switches(Layer2) 


The ubiQuoss Access Switches includes full-featured, managed, Layer 2 and Gigabit Ethernet, and Power Over Ethernet switches. Gigabit Ethernet Switches provides affordable, higher capacity switching for Gigabit-to-the-desktop applications and PoE. The Gigabit Ethernet switch is available from 8 to 24 ports and features 1G or 10G uplink capabilities for both multi-floor and campus aggregation switching needs that demand multi-layer, wire-speed switching capacity.
Business-class features, flexible management, and a favorable price point set these switches apart from all other switches in their category.

The ubiQuoss Acccess solutions are perfect for Small- and Medium-sized Businesses (SMBs) or multi-site enterprise networks. These solutions address highest networking priorities, from bandwidth expansion to network security.

Gigabit Ethernet L2 PoE Switch




The ubiQuoss E4020-24P is a Layer2 Gigabit Ethernet workgroup PoE (Power over Ethernet) switch. It passes power and data on Ethernet cabling so that there is no need to supply electrical power to PD enabled network devices such as wireless AP, CCTV, and VoIP Phone. PoE provides flexibility on installation space, and significantly reduces the installation cost. Its efficient network structure is especially useful for IP Surveillance, Wireless LAN and Train Rail/Expressway Networks.


Suitable for direct connection to WiFi AP, IP surveillance terminal, transportation network terminal, it provides an economic and high performance switching service (1000Mbps link speed) with electrical power through Ethernet cable (CAT 5e).


The E4020-24P can have up to 24 PoE embedded (IEEE802.3af for 24 ports/ IEEE802.3at for 12 ports) fixed 10/100/1000base-TX (UTP RJ-45) ports and four 1G/10G SFP/SFP+ interfaces. All ports of E4020-24P switch support full duplex communication, allowing both directions of traffic to flow at the same time and doubling the link bandwidth extension.

E4020-24P supports hardware-based bandwidth management, and Quality of Service functionality, which enable corporate users and ISPs to provide differentiated internet services in the environment of broadband building or facility network.


The E3010-08P supports hardware-based bandwidth management, and Quality of Service functionality, which enable corporate users and ISPs to provide differentiated internet services in the environment of broadband building or facility network.
