Understanding Power Consumption of PoE Ethernet Switch

As PoE changes to meet today’s increasing application requirements like IP cameras or WiFi access points, it’s widely used for enterprises networks. Using a PoE or PoE+ switch, technicians can simplify the cabling installation because the PoE technology can support power and data transmission over the same cables. When choosing a PoE Ethernet switch, we always care about the ports and power consumption most. This article will introduce the power consumption of PoE Ethernet switch and take two PoE Ethernet switches as examples to explain power consumption.

What Is Power Consumption of PoE Ethernet Switch?

At present, PoE power consumption follows two standards, IEEE 802.3af and 802.3at. The original IEEE 802.3af rules that power consumption on each port of a PoE network switch can be up to 15.4W. The updated IEEE 802.3at standard also named PoE+, which is backward-compatible with IEEE 802.3af, provides up to 25.5W of power on each port. However, because the power dissipate exists in cables, the minimum output power assured on each port for PoE switch is 12.95W, and 25.5W for PoE+ switch.

power consumption standard

Figure 1: IEEE 802.3af and IEEE 802.3at standards.

The key to successful PoE installation is to ensure that the selected power over Ethernet switch provides the necessary watts of PoE required for each device, and the total power consumption also must be guaranteed for powering all devices. Simply put, the total power consumption of all the connected devices must be controlled in the range of the PoE switch max power consumption.

How Many Devices Can I Connect to My PoE Ethernet Switches?

Power consumption of 150W and 400W are the most popular choices on the market. The following are two switches from FS, 8 port PoE switch and 24 port PoE switch, and we’ll use them to further explain the question how many devices can we connect to my PoE Ethernet switches.

PoE Ethernet switches applications

Figure 2: How many devices can be connected to a PoE switch?

How Many Devices Can the 8 Port PoE Switch Connect?

FS S1150-8T2F switch is a managed PoE+ switch. It has 8 10/100/1000Base-T RJ45 ports, and 2 Gigabit SFP slots. Its PoE standard complies with IEEE802.3af/at. And designed with a max power consumption of 150W, each port can support up to 30W power. This means the switch provides the availability of PoE on all 8 RJ45 ports, and each port can potentially power devices that are connected. From the above, we know the standard PoE can supply 15.4W power for each port, and 30W for PoE+. Therefore, this switch can simultaneously connect 8(15.4W×8=123.2W<150W) devices that use IEEE 802.3af standard, and only 5(30W×5=150W) devices that use IEEE 802.3at standard. For example, if a typical outdoor IP camera needs a PoE power of 20W, the connection of 7 typical IP cameras will require 140W of PoE power (7×20W), which is well within the power consumption of this network switch.

How Many Devices Can the 24 Port PoE Switch Connect?

FS S1400-24T4F managed PoE+ switch is designed with 24 Gigabit PoE+ ports, 1 console port and 4 Gigabit SFP ports. This switch complies with IEEE 802.3af/at with a max power consumption of 400W and 30W for each port. Through a calculation, we know the 24 port switch can connect 24(15.4W×24=369.6W<400W) devices with PoE standard at the same time, and support 13(30W×13=390W<400W) devices with PoE+ standard. And as for the same outdoor IP camera with a power requirement of 20W, the 24 port switch can support 20(20×20W=400W) cameras.

Conclusion

Knowing the power consumption of PoE Ethernet switches is very important. If you want to connect multiple devices to a PoE switch, you need to calculate the total power consumption that all the devices require, and make sure you PoE switch can provide the needed current.

How to Choose a Gigabit Network Switch?

Gigabit network switch is the most commonly used equipment in data centers. Before choosing the best network switch for the current or future network, people can type “Ethernet switch” into the online shopping site or search engine, they may find a ton of listings for switches of all kinds and price levels. It’s not an easy job to find one. Then how to choose a Gigabit network switch in order to avoid buying the wrong device or overspending needlessly?

Types of Gigabit Network Switch

Gigabit Ethernet switch can be divided into unmanaged, managed and PoE categories.

Unmanaged switches use the plug-and-play design that means they only allow Ethernet devices to communicate with one another. They are shipped with fixed configuration and don’t allow any changes to this configuration. This type of network switch is normally found in home networks or small business.

Managed switches offer all the features of unmanaged switches and are capable of configuring, managing and monitoring one’s LAN. Users have greater control over how data travels over the network and decide which one has access to it.

PoE switches support electrical power and data transmission over one network cable, which will greatly simplify the cabling process. Using a PoE switch, people don’t need to worry about power outlet when deploying network devices.

Features of Gigabit Network Switch

With a network switch, users can have different networked devices on their desks as well as bandwidth-intensive applications that require high rates of data transmission and no tolerance for congestion. These switches are the basics of modern wired network. They can not only provide the connections to PCs and other devices in a wide variety of fields, but also support the cloud storage of servers. With new trends like SDN and the IoT transforming the industry, people have to get the features that they need from the switches, so that they would know which switch is the one that they need.

How to Choose a Gigabit Network Switch?

Here are the most important facts you should consider when choosing a Gigabit network switch.

  • Choose the role of the switch. If you are just looking for a device to extend your wired network at home, one unmanaged switch is suitable. And an 8 port Ethernet switch or 12 port switch is enough for home network. If you want to find a switch for a large network, you may buy one or more managed switches acting as core switches. 24 port and 48 port PoE managed switches are the right choice.
  • Choose the forwarding rate of the switch. Gigabit switches have different processing rate. Processing and forwarding data rates are very important. The processing rate becomes lower, the forwarding rate will be slower. This may make the switch unable to accommodate full wire-speed communication across all the ports. So people should figure out what forwarding rate they need before buying a Gigabit switch.

Conclusion

From the above, we know how to choose a Gigabit network switch. If you have decided to buy a network switch, welcome to visit FS.COM. FS has a good selection of 10Gb switch, 40G or even 100G switch and PoE switch for home and office users.

How to Mount a Network Switch to a Rack?

A network switch has been recognized as one of the most important devices for today’s networking technology. It allows simultaneous transmission of multiple packets and partition a network more efficiently than bridges or routers. The rack mount switch can be installed in a standard 19-inch equipment rack or on a desktop or shelf. So how do you mount a network switch to a rack to establish network wiring connections? Here’s a step-by-step guide to teach you how to mount a network switch to a rack.

Preparations Before Mounting the Network Switch

Before rack mounting the switch, please pay attention to the following factors:

  • Location: The site should be at the center of all the devices you want to link and near a power outlet, so that it is accessible for installing, cabling and maintaining the devices in the rack.
  • Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range (0 to 40 °C).
  • Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.
  • Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
  • Grounding: The switch rack should be properly grounded.

How to Mount a Network Switch to a Rack?

Step3. Adding Other Switches into the Rack

If there is only one data switch to be installed in the rack, then you can make the connection to a power source now. If there are multiple switches to be mounted, you need to install the another switch on the top of the first one in the rack, and then attach the power cords.

Step4. Attaching the Power Cords

After you complete mounting all of the switches in the rack, it’s time to connect the switch rack to the power source. Remember to verify that you have the correct power supply (AC-input or DC-input and the correct wattage) for your configuration.

Caution: To prevent bodily injury when mounting or servicing the switches in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

  • This network switch should be mounted at the bottom of the rack if it is the only unit in the rack.
  • When mounting the switch in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the switches in the rack.

Establishing Network Wiring Connections

After mounting your network switches to a rack, you can establish the network wiring connections according to your requirements now. If you’re using a Gigabit Ethernet switch, it can be connected to 10, 100 or 1000Mbps network interface cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers. No matter which type of network switches you are using, make sure that they are securely mounted in the rack and connected to the corresponding networking wiring systems.

Cloud Computing vs Big Data: What Is the Relationship?

Cloud computing and big data are two of the most trending terms in the ever-lasting IT sector nowadays. You may think that they both do the same thing but actually, both of them have their own ways to work to perform. Cloud computing vs big data, what are they? What is the relationship between them?

cloud computing vs big data

Cloud Computing Tutorial

Cloud computing is a technology used to store data and information on a remote server rather than on a physical hard drive. It uses the servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. It means accessing resources of organization from any remote location in the world. In simple term accessing RAM, HDD, Processor of organization’s server from laptop, desktop from any of the location where Internet is available.

what is cloud computing with example

As shown in the figure above, cloud computing is collection of different services, providing services to end user via the Internet. Services like storage, virtual desktop applications, Web/App hosting process power from servers. In the following architecture, the infrastructure built to provide services is called cloud computing. This infrastructure from where the services gets accessible is front end.

Big Data Wiki

The term big data is very popular nowadays, representing huge sets of data that can be further processed to extract information. Big data carries hidden patterns and algorithms which are unlocked by using various tools available in the market. These data sets are further analyzed to provide business insights. Big data is all about storing and processing of data that is exponentially growing these days. Giants like Google, Facebook are having their own data centers to keep track and to secure their users’ data. That’s also why many big companies are equipped with reliable network equipment (including the server, router or fiber switch) for data storage or traffic forwarding in their data centers. For high performance and cost-effective enterprise routers, Gigabit Ethernet switch and 10gbe switch, FS is a case in point.

what is big data technology

Big data requires a large amount of storage space. While the price of storage continued to decline, the resources required to leverage big data can still pose financial difficulties for SMBs (small to medium sized businesses). A typical big data storage and analysis infrastructure will be based on clustered network-attached storage (NAS). Clustered NAS infrastructure requires configuration of several NAS pods with each NAS pod comprised of several storage devices connected to an NAS device. The series of NAS devices are then interconnected to allow massive sharing and searching of data.
