Removing the module

To remove a module:

 

 

1 If the switch is already operational, disconnect it from the main

 

power supply.

 

 

2 Follow the instructions in “Avoiding damage to the circuit

 

board” above.

 

 

3 Unscrew the screws securing the module.

 

4 Pull the module gently to disengage the connectors fully from

 

the socket on the motherboard. Slide the module out com-

 

pletely.

 

 

5 Cover the empty module port with the plate and secure using

 

the screws.

Use shielded cables

Shielded cables normally comply with EMC and FCC emission lim-

 

its.

 

 

Only use unshielded cables when it is explicitly specified in the in-

 

stallation manual of the device in question.

Cables for the LAN Ports

Ports on the switch are wired MDI-X, so use the following cable:

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.
