In an equipment rack	To mount the switch in a standard equipment rack:
	1 Attach the mounting bracket marked “Left” to the left-hand side
	of the switch, and attach the mounting bracket marked “Right”
	to the right-hand side of the switch, using the four screws pro-
	vided.

Make sure that you attach the mounting brackets to the correct sides. Otherwise the switch will not align correctly in the equipment rack.

	2	If the four rubber feet prevent the switch from standing firmly
		on the equipment rack’s side support rails, remove them.
	3	Set the switch in the equipment rack, and make sure there is
		adequate space for air flow around the switch (see “Allow ade-
		quate ventilation” in “Positioning and Installing the Switch”, p.
		7).
	4	Screw the mounting brackets securely to the equipment rack.
Ambient temperature	If the switch is installed in a closed or multi-rack assembly, the oper-
	ating ambient temperature of the rack environment may be greater
	than the ambient temperature of the room. Make sure that the temper-
	ature of the rack environment does not exceed the recommended op-
	erating temperature for 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.
