sion 1.0 and 2.0) or a fast access device (such as a server) to the

 

switch’s RJ-45 ports using UTP cable (Category 5):

 

1 Make sure that the device has a 100Mbps (100Base-FX or 10/

 

100Base-TX) network interface card installed.

 

If not, use your network interface card’s documentation to

 

install and configure it correctly.

 

2 If your workstation is fitted with an RJ-45 interface then there is

 

no problem. However, it is possible to attach to other connector

 

types using an appropriate adapter. For example, use a UTP/

 

10Base-FL adapter for fiber connections

 

3 Connect one end of the UTP cable to an RJ-45 port on the

 

switch.

 

 

 

According to IEEE 802.3, the cable length must not exceed 100

 

meters (approximately 325 feet).

 

4 Connect the other end to the 100Base-TX connection on the

 

device.

PC must not use frame tagging. To manage the switch from a PC with

 

IEEE 802.1Q tagged frames, management must be through a device

 

which untags the frames.

Cable for the Console Port

If you connect a PC (via the Console Port), then use a null-modem ca-

 

ble.

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.
