C H A P T E R 7 Console Port Use and Troubleshooting

If the problem is still not isolated

3Check for any relevant messages in the Trap window. Use of this tool is described in “Trap Window”, p. 38.

4Check for any relevant messages in the System window.

The System Log gives details about system events that occur during start-up and operation and also the general state of the switch. Typical information recorded in the System Log includes all major events during start-up, system changes, unexpected events and configuration errors. The System Log reports such things as software successfully located and loaded, ports enabled or disabled, and if any SNMP traps have been sent. Use of this tool is described in “System Window”, p. 39

5Check for any relevant messages in the Errors window. Use of this tool is described in “Errors Window”, p. 39.

6Check the fault counters on the switch ports and watch for any significant error counters.

Further Evaluation of the Problem

If you still cannot resolve the problem after following the procedures above, access the Monitoring menu within Local Management. Mon- itoring is a valuable tool for the troubleshooting process and offers extensive information on the performance and the status of the switch hardware and software, the switch ports and the traffic patterns on each port.

The general facilities available within the Monitoring menu are de- scribed in the following subsections. The use of these facilities de- pends on the problem and on any relevant information collected in the previous procedure.

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.
