The importance of having the correct psu
The computer server is the most vital link in your office network. Apart from connecting and sending data to and from the other computers linked to it, it also acts as the gateway to the internet, routing all outbound and inbound traffic. If any other PC in your network breaks down, it will hamper work slightly. However, in case the server crashes, it leads to a virtual shutdown of all the other computers in your office. More often than not, erratic power supplies are the main cause of computer crashes. Therefore, it is vital to use the best power supplies for your office's server.
EFM - ethernet first mile
EFM is a great ne modern technology that is inexpensive and suitable for providing reliable VPN and VoIP services. It is covered by an SLA guarantee, making it suitable for mission critical business applicants. EFM uses traditional fibre leased lines bringing connectivity within the reach of small businesses. It is available to 80% of UK businesses and can be installed in around 45 days, half the time of a fibre installation.
Maintaining proper voltage and regulating temperature
It sucks out air heated by the transformer allowing cool air to flow in through air vents in the case. This helps to cool down the transformer as well as the other components inside the computer. The switched mode corrects any changes in input voltage, ensuring that no voltage surges takes place in the power being supplied to the motherboard, CPU (central processing unit), HDD (hard disk drive) DVD (digital versatile disk) player, and other components. Since the SMPS is the heart of the computer, you should always pay more and purchase a model manufactured by a reputable company.
Maintaining voltage supplied to your server
You should also ensure that your server receives a pure sine wave power supply. For this, you need to install either a CVT (constant voltage transformer) or a UPS (uninterrupted power supply) between the power outlet of your office and the power inlet to the server. It is better to purchase a UPS. It contains a battery, charged by the power from the mains. When a power failure occurs, the battery takes over. A circuit converts the 12 volt DC power output of the UPS to the appropriate AC (110 or 220) voltage. Instead of going for a manual relay switch model, purchase a model that contains an electronic switch. This allows the switchover of the power supply from the mains to the battery almost instantaneously.
Sine or Square
You should always purchase an UPS that provides a sine wave power output. This type of supply has no sharp peaks, which can damage sensitive electronic equipments. You should also check if the UPS contains a magnetic filter. This helps to prevent magnetic waves emitted by it to reach the computer. Never go for a modified sine wave model. It might be cheaper but its output power is not as smooth as those provided by a pure sine wave UPS.
