As we all know, network switches are always a little bit noisy. Many people are bewildered by this problem. In fact, the noise mainly comes from the multiple fans that operate from within the network switch, in order to cool the various components of the switch from within. Considering the certain situation when some SMB might prefer having a fanless network switch, a brand new S2800-24T4F fanless switch has been introduced to meet the silent and cost-effective requirement for SMB customers. Let’s take a closer look at this energy-saving S2800-24T4F fanless switch. What Is Fanless Switch? In some scenarios, operating fans within the network switches is inevitable. It is the reason that the switches emanate so much heat, especially when multiple network switches are locked up into a rack along with many other active devices. At this time, fans play a important role to help cool various components within the network switch. However, the constant noise coming from the fans withi...

Today, small and midsize businesses are embracing mobile and cloud technologies to improve employee productivity and engage with customers. More business needs an affordable, high-performance and secure wired and wireless infrastructure that can support the growing number of mobile devices and cloud-based applications. When asking for a recommendation for SMB switches, many people always recommend the HP because it has most of the same capabilities such as full management capability, rock solid operation and great support (as the Cisco), but at half the price. And HP 1810-48G switch is one of such SMB switches. This article intends to give a simple introduction to HP 1810-48G switch and provide compatible SFP transceiver solutions for it. HP 1810-48G Switch (J9660A) The HP 1810-48G switch is a basic smart managed Gigabit Ethernet Layer 2 switch that is designed for small businesses. This HP ProCurve 48 port gigabit switch has four additional true Gigabit Ethernet SFP ports (...

A network switch is a small hardware device that centralizes communications among multiple connected devices within one local area network (LAN). Network switches come in different sizes, features and functions, so choosing a switch to match a particular network sometimes constitutes a daunting task. This blog will give you a few useful things to consider when choosing the appropriate switch for a layer in a particular network. Network Switch Technology While switching capabilities exist for several kinds of networks, including Ethernet, Fibre Channel, RapidIO, ATM, ITU-T G.hn and 802.11, network switch can operate at one or more layers of the OSI model. Switches provide multiple advantages in network designs. All switches provide the basic traffic filtering functions, which improves network bandwidth. Besides, the internal switching circuits allow traffic flows to simultaneously occur between multiple ports. Currently, mainstream network switches support Gigabit Ethernet sp...
