C H A P T E R 1 Intel Express 520T Switch

 

Connecting the Power

Introduction

After connecting the devices to the switch, connect the power cable.

 

There are certain practical and safety considerations to be made be-

 

fore powering the switch on.

 

 

The Power Cable

 

Ground warning

The switch is delivered with a power cable that fits the power sockets

 

in your country. If this is not the case, contact your dealer immediate-

 

ly and ask for the correct power cable.

Power cable wiring color

The wires in the power cable provided are color coded:

Important for UK use

If the colors of the wires in the power cable provided do not corre-

 

spond with the markings that identify the terminals in your plug:

 

1 Make sure that the green and yellow wire is connected to the

 

terminal marked with the letter E, or with the ground symbol

 

, or is colored green and yellow.

 

2 Make sure that the blue wire is connected to the terminal

 

marked with the letter N or colored black.

 

3 Make sure that the brown wire is connected to the terminal

 

marked with the letter L or colored red.

Power supply to a rack

If the switch is installed in a rack, make sure the rack’s power supply

 

socket has a ground connection and the rack is connected to a branch

 

supply or a power supply socket with a ground connection.

To avoid overloading the circuit and damaging the wiring of the pow- er supply, the power supply to the rack must be adequate to cover the extra power consumed by the switch.

520T specifications

The Intel 520T is a well-regarded member of Intel's Xeon processor family, designed primarily for entry-level servers and workstations. Built on the 32nm manufacturing process, the 520T is based on the Nehalem microarchitecture, which has paved the way for improved performance and efficiency in data processing tasks.

One of the standout features of the Intel 520T is its energy efficiency. With a thermal design power (TDP) of just 35 watts, it provides an excellent balance between performance and power consumption. This characteristic makes it particularly suitable for environments where energy costs are a significant concern, such as in data centers or small business server applications.

Equipped with four physical cores and hyper-threading technology, the 520T allows for eight threads of execution, enabling it to handle multi-threaded workloads effectively. It operates at a base clock speed of 2.2 GHz and can achieve turbo boost frequencies up to 2.5 GHz under optimal conditions, ensuring that it provides the necessary performance for demanding applications.

The processor supports Intel's trusted execution technology and virtualization technology, maximizing both security and performance in virtualized environments. This capability allows multiple operating systems to run simultaneously on a physical server, making it an excellent fit for businesses looking to optimize their assets through virtualization.

The Intel 520T also features Intel's QuickPath Interconnect (QPI) technology, which provides a high-speed connection between the processor and other components, such as memory and storage. This feature helps minimize latency and maximizes bandwidth, enhancing overall system responsiveness.

In terms of memory support, the processor can handle up to 32 GB of DDR3 RAM, providing ample capacity for demanding applications. The 520T also supports ECC (Error-Correcting Code) memory, which is vital for mission-critical applications that require data integrity.

Security enhancements are another noteworthy aspect of the Intel 520T. With built-in security technologies, including hardware-based random number generation, the processor helps safeguard sensitive data and contributes to more secure computing environments.

Overall, the Intel 520T stands out as a robust option for users seeking an efficient server-grade processor capable of delivering strong performance while maintaining a low power profile. Its array of features, technologies, and characteristics make it a reliable choice for various computing needs.
