	Positioning and Installing the Switch
Allow adequate ventilation	The switch contains two fans to air-cool the internal circuitry. The air
	is drawn in from the left of the unit and expelled through the outlet
	grills on the right side and the rear.
	To ensure correct airflow, leave 100 mm (4 inches) free space on both
	sides and behind the switch. Do not allow the intake or outlet grills to
	become blocked.
On a desktop	To install the switch in a desktop environment:
	1 Find the four rubber feet in the pack that contains the rack
	mounting kit.
	2 Remove the backing strip from each of the four feet.
	3 Attach the four rubber feet to the underside of the switch (to
	ensure that the switch stands firmly).
	4 Place the switch on a stable, flat surface.
	5 Ensure that the air intake (on the left) and fan outlets (on the
	right side and rear) are not blocked.
	Warning The switch’s lifetime and operational reliability can
	be seriously degraded by inadequate cooling.
Rack requirements	Install the switch in a standard rack in accordance with IEC 297 (or
	similar); if the minimum outside measurements of the rack are 600 x
	600 mm (23.5 x 23.5 inches), you must allow 190 mm (7.5 inches) of
	space at the rear.
Mounting kit	The switch is delivered with a kit to attach it to a standard 19-inch
	equipment rack (with side support rails). The kit contains two mount-
	ing brackets and four screws (for attaching the brackets to the sides
	of the switch).
Tools required for	In addition to the mounting kit, you need the following items to

	• Standard 19-inch rack with side support rails.
	• 3 mm screwdriver.

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.
