. Because the connection media used here is an optical fiber cable, for this reason, the author conducts one-by-one investigation and tests on factors such as the Optical Fiber adapter, the fusion joint at both ends of the optical fiber, the trunk cable of the optical fiber, and the optical fiber jumper through troubleshooting methods. No suspicious phenomena were found, during the above troubleshooting and testing, we occasionally saw that the new vs

This article introduces the structure and Prospect Analysis of the smart cabling system. Many people may not know about the smart cabling system. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. "The main reason why smart cabling systems began to emerge in the 1980s S was that network administrators were struggling to manually record cabling link information, they also want to monitor the cabling system in rea

cable of the optical fiber, and the optical fiber jumper through troubleshooting methods. No suspicious phenomena were found, during the above troubleshooting and testing, we occasionally saw that the new vswitch of A sub-network can be connected to the core vswitch of the LAN, but it was immediately disconnected several seconds later. Is it possible that the new switch in subnet A does not properly set the working parameters? Taking this into consid

better than FSB. The speed of FSB is usually closely associated with the speed of the front-end bus and memory. So when you raise the CPU FSB, the performance of the CPU, system, and memory also increases. 　　There are two main ways of CPU overclocking: One is hardware settings and the other is software settings. Hardware settings are more commonly used, it is divided into jumper settings and BIOS settings two kinds. 1.

-density fiber optic cable rack, so that the back of the line cleaner, more convenient maintenance. As the core of the central distribution area MDA, the plug-and-play modular features are adopted according to the demand of the data center, and the wiring frame takes into account the excessive arc of the line and the fiber distribution line, and increases the bending radius protection of the optical cable. The fiber optic module features a 12-core or 24-core high-density connection capacity stru

transmission cable and the related connection hardware, the modular design. So all the channels are generic. Each channel can support terminal, Ethernet workstation and Token Ring workstation. All equipment opening and changes do not need to change the wiring, just add or subtract the corresponding application equipment and in the wiring rack to carry out the necessary jumper management. In addition, the network can be flexible, even in the same room

information outlets and shielding jumper shielding layer and network equipment of the shielding layer interoperability. When a device plugs a power cord into a power outlet, it is automatically grounded by a protective conductor (PE). Shielding wiring system without grounding, anti-interference ability is still better than unshielded wiring system According to the test data of the third party test lab, it shows: in the normal good grounding situati

than FSB. The speed of FSB is usually closely associated with the speed of the front-end bus and memory. So when you raise the CPU FSB, the performance of the CPU, system, and memory also increases. There are two main ways of CPU overclocking: One is hardware settings and the other is software settings. Hardware settings are more commonly used, it is divided into jumper settings and BIOS settings two kinds. 1.

hard drive, optical drive, and other IDE devices. If the hard drive is set as the primary device, be sure to install it on the main device interface of the IDE's data cable, and if you set it from the device, be sure to install it on the interface, or an error will occur. Standard IDE data cables, different colors of the interface for different purposes. When connecting to a data cable, be careful not to reverse it. 　　Hard drive jumper In addition

and which device cannot be connected, but cannot tell the Administrator the location of the physical error and the cause of the problem, whether the cable is disconnected or the plug is detached. The connection from the traditional switch port to the distribution frame port is completed through a jumper. Once the jumper is changed during completion, manual change drawings must be recorded for future query.

Method Open the chassis, find the battery on the motherboard, and disconnect it from the motherboard (that is, remove the battery). At this time, cmos will lose all internal storage information due to power failure. Connect the battery and shut down the chassis to boot. Because cmos is blank, it will no longer require you to enter the password. At this time, enter the bios setup program, select "load bios default" (default value for loading bios) or "load setup default" (default value for loadi

Misunderstanding analysis of electronic distribution frame selection is as follows: 1st misunderstandings, 9-pin jumper is not an international standard. The 9-pin patch cord technology has been mentioned many times. People who have been in touch with the wiring or network know that the network cable has 4 pairs, the corresponding RJ-45 plug and port is also 8-pin. So there are 9-pin jumpers that do not comply with international standards. But few peo

What to do if the CPU fan turns the motherboard does not start 1, CPU aspects of the problem CPU does not have power: Use the multimeter to test the three (or one) field tube around the CPU and three (or one) rectifier diode, check the CPU is damaged. CPU socket has a shortage of needles or loose: This type of fault performance is not lit or irregular crash. You need to open the upper cover of the CPU socket surface and carefully observe whether there is a deformed pin. CPU Socket Fan Fixed

Some use a bit longer computer, their own motherboard is always the problem of BIOS reset, the motherboard has overclocking set, all lost, the processor back to the default frequency. Many users will think that the motherboard battery is dead, sometimes replaced the battery failure is still, we may wish to use the following steps to see what is the failure caused by the motherboard is often the problem of the BIOS reset. The battery on the motherboard does not power, causing BIOS in

Computer power-on display CMOS setting wrong This problem often appears on the ASUS motherboard, generally have this jumper basic is ASUS Motherboard, Asrock also have. A friend who has this problem can try to solve it. Shorten the 5-6/7-8 USB mode jumper on the motherboard to 1-2 pins. The motherboard factory defaults to skip to 1-2, is the backup mode, support USB device wake-up device, hate this functio

The usernames and passwords of sysdba/sysoper users can be verified by password files, log on to the database before it is started. If there is no password file to start the database, you can only pass operating system authentication before the database is started. when Rman is used, the database needs to be processed in no

Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails. Optical fiber jumper (also known as optical fiber connector), that is, the optical fiber connectors connected to optical modules, also have many types, and they cannot be used with e

First, High available HA (high available) is highly available and is also known as a dual-machine hot standby for critical business. The simple understanding is that there are two machines A and B, the normal is a service, B standby idle, when a down or service outage, will switch to the B machine to continue to provide services. Commonly used high-availability open source software has heartbeat and keepalived, where keepalived has load-balanced functionality. Ha can also be used in MyS
