NA338TB3 Q: How do you access the mounting screws on the side of the ports? Is there a way to power on the Mac mini through the unit? A: The following web-link will direct you to a video that tells the users how to set up the NA338TB3 with the Mac mini computer. In the…
NS388P Q: Does the NS388P support SSD dual porting? A: The NS388P storage (model: NS388P-D2) supports U.2 PCIe NVMe 3.0 2×2 dual port 2.5-inch SSDs including Techman XC120, Intel SSD DC D3600 series and Intel SSD DC D3700 series…etc. http://tm-ssd.com/product-xc120.html https://www.intel.com/content/www/us/en/products/memory-storage/solid-state-drives/data-center-ssds/dc-d3600-series.html https://www.intel.com/content/www/us/en/products/memory-storage/solid-state-drives/data-center-ssds/dc-d3700-series.html On the other hand, the other NS388P storage model ‘NS388P-S4’ only supports U.2…
We live in an age that is fully saturated by technology and data consumption, and what’s more is that the amount of data we consume is growing exponentially with each and every new generation of computer chips and phones. Every medium is trending towards higher and higher fidelity but in this fast-lane paced society, nobody…
Switching power supplies are basically certified to IEC 60950-1. In general, the power supply’s safety reports and certifications are required for the actual installation besides the manufacturer’s datasheet. Failure to follow these can cause delays when system certification is required. Normally there are three main documents involved: CB certificate, IEC 60950-1 CB report and/ or…
In general, power supplies that meet the IEC 60950-1 safety standard are designed to operate at commercial and residential areas, where altitude can vary from slightly above sea level to as high as 2,000 meters. However, many power supply manufacturers provide units that are designed to operate at higher altitudes, up to 3,000 meters or…
All power supplies have a specified “Operating temperature range”. For example, a particular 500W switching power supply has an operating temperature range from “-20°C to +70°C”. However, the specification may also state “Output derating linearly above +50°C”. So what does this mean? Most power supply manufacturers provide output derating curve (see figure below) to make…
Most AC-DC and DC-DC power supplies have internal current protection circuits to protect the power device and the majority of Over Current Protection (OCP) circuits include an automatic recovery feature. Power supplies that have only one OCP circuit are called “single-rail” while the power supplies that have more than one OCP circuits are referred to…
In an ideal world all the energy input to a power supply would be converted to useable electrical output power. Unfortunately real life systems incur losses and like all other types of power supplies, open frame power supplies generate heat which has to be dissipated during system operation. Key components that contribute to such losses…
The open frame power supply is generally a switching power supply consisting of just a PCB board and no enclosure. Open frame power supplies are designed specifically to be used inside of end products with specialized designs that provide an enclosure. Typically, the whole system will share one enclosure. Typical areas of concern when installing…
Server cabinets and open server racks ultimately server the same purpose, but their differences do define some noteworthy advantages and disadvantages, which can make choosing between the two difficult. However, which best suits you will ultimately be up to the environment that you plan to put your cabinet or rack in as well as your…
What is a Power Factor? When a power supply draws current from the wall (grid), it’s not always doing so in the most efficient manner. Power supplies that don’t have any kind of PFC or Power Factor Correction are likely to draw current in short bursts due to the nature of the energy coming from…
If you’re looking to invest in new server equipment, chances are, you’re also looking for the right server racks to go with it, but with all of the options available and all of the factors to consider, it quickly becomes clear that choosing the right server cabinet or open rack is not the easiest thing…
