Smart Managed Switch Vs. Unmanaged Switch

Network switch, a box-shaped device, plays an important role in a network deployment. To achieve high network performance, a suitable switch is required. There are smart managed switch and unmanaged switch on the market. How much do you know about them? Smart managed switch vs. unmanaged switch, which one should you choose for your network deployment? Keep reading, and you will find the answer.

Smart Switch Vs. Managed Switch

If you look through the official website of several vendors, you may find that some offer smart switch, the others provide managed switch. Smart switch vs. managed switch, what’s the different between them? Smart switch has some features that managed switch has, but are more limited. Besides, smart switch is cheaper than managed switch. So, it’s a cost-effective alternative to managed switch. In fact, “smart switch” and “managed switch” are terms invented by vendors. And the exact meaning may vary from vendor to vendor. To some extent, smart switch and managed switch are virtually the same. In the following part, I combine them as smart managed switch for easy reading.

Smart Managed Switch Vs. Unmanaged Switch

As smart managed switch and unmanaged switch have different features, they are used in different applications.

Smarted Managed Switch

Smart managed switch offers features like QoS (Quality of Service), Simple Network Management Protocol (SNMP), command line interface (CLI), Rapid Spanning Tree Protocol (RSTP), redundancy capability, VLANs, LACP and so on. The greatest advantage of smart managed switch is that you can change the configuration of the switch to satisfy your specific networking needs. Smart managed switch is especially suitable for enterprises that need to manage and troubleshoot their network remotely and securely, allowing network managers to monitor and control the traffic to achieve optimal network performance and reliability. The following figure shows FS S5800-8TF12S smart managed switch which provides high port density with 8-port 1GbE RJ45 and 8-port 1GbE SFP combo and 12-port 10GbE uplink in a compact 1RU form factor.

Unmanaged Switch

Unmanaged switch is basic plug-and-play switch with no remote configuration, management, or monitoring options. It allows Ethernet devices to communicate with one another (such as a PC or network printer) by providing a connection to the network and passing on information to where it needs to go. Therefore, unmanaged switch is usually used to extend the number of Ethernet ports. Unmanaged switch can be desktop or rack mounted. It is less expensive than smart managed switch and is suitable for home use, SOHO and small businesses.

Which One to Choose?

From the above content, we can conclude that smart managed switch vs. unmanaged switch, the biggest difference between them is the configuration feature. As for which one to choose, it really depends on your need. If you just want to set up a home network or add more Ethernet ports, unmanaged switch is good enough. If you need configuration options like VLAN and QoS, you will have to use smart managed switch.

A Closer Look at Fanless Switch

If your laptop has built-in fan, you must have gone through such experience: when your laptop has been working for a long time, it will be heating. Then, you may start the fan to cool your laptop down. However, there will be noise. So does network switch. Compared with other optical components, network switch is larger. And ongoing work will cause overheating. Therefore, many network switches are designed with fans and very noisy. Is there any solution that is the best of both worlds? The answer is “Yes”. Fanless switch can do this. This article will guide you have a closer look at fanless switch.

Overview of Fanless Switch

Taken literally, fanless switch does not have any fans built into it, thus it has a quiet operation. But how is it cooled down? In fact, engineers employ passive cooling system for fanless switch to transfer heat. The passive cooling system achieves high levels of natural convection and heat dissipation by utilizing a heat spreader or a heat sink to maximize the radiation and convection heat transfer modes. Therefore, it can provide energy efficiency and lower financial cost. With passive cooling system, fanless switch is a cost-effective and energy-efficient solution that maintains optimal operating temperature without causing much noise.

While fan switch utilizes active cooling system which refers to cooling technologies that rely on an external device to enhance heat transfer. Through active cooling system, the rate of fluid flow increases during convection, which dramatically increases the rate of heat removal. Apart from the unpleasant noise, the main disadvantage of active cooling system is that it requires larger power consumption and costs more than passive cooling system.
