How does the Internet bar switch fail?

Internet Café switch is a hardware product, the fault is also diversified, which requires the experience of network management. Then for some new or professional technology is not very good network management, the Internet café switch failure, how should be excluded it.

Next share to my personal experience of the Internet bar Switch Troubleshooting method:

One: When the Internet café switch failed, the first signal is the Internet Bar Network connection is not, so often from the client to start checking. We can follow the client computer-> Port module-> Horizontal cable-> jumper-> switch Such a route, check each one, first to eliminate the possibility of remote failure.

Two: And do not first rush to open the exchange, first from the system configuration or system software to proceed to the investigation. If the software does not solve the problem, then the hardware is a problem.

For example, a port is not good, then we can first check the user is connected to the port is not the corresponding VLAN, if the system and configuration to eliminate the various possibilities, it can be suspected that the real problem is the hardware failure.

Third: If there is a failure of the switch, first from the outside of the various lights to identify, and then according to the fault instructions, and then check the internal corresponding parts whether there is a problem. For example, powerled for the green light to indicate that the power supply is normal, extinguished indicates no power supply;

Linkleds Yellow indicates that the connection is now working in 10mb/s, Green is 100mb/s, and off means no connection, flashing indicates that the port was manually shutdown by the administrator.

Rdpled indicates a redundant power supply; Mgmtled represents the Administrator module. These several need to be clear, whether or not from the outside of the fault, you must login to the switch to determine the specific fault location, and to carry out the appropriate measures to arrange the obstacles.

No matter what kind of fault the Internet Café switch, the network administrator should know how to eliminate, and the Internet Café Switch fault maintenance, of course, knowledge or to accumulate their own.
