Depth description of the switch failure phenomenon
The following explains what is cisco switch failure, switch failure caused by many kinds of problems, such as the motherboard overheating caused the whole machine can not run the power capacity is too small, not able to meet the overall operation of the switch.
Ordinary computers in the LAN mutual visits as usual, but why access connected to the switch host, speed is obviously not normal, will not be a loose connection in the switch or the switch performance is unstable ?
I intend to use ordinary switch to replace this failure switch. In my power cut off the fault switch, ready to hand to be taken out to be replaced, I was surprised to find the surface of the device is very hot, and the surface temperature of the Web server host is also high, the hand near the vicinity of these devices.
can obviously feel the heat in the air, it appears that the switch is in a serious "fever" status will not be a "fever" of the switch, causing the other computer normal access to important host connected to the switch? "fever" in order to verify his suspicions, I will seriously switch and the power of
In order to solve the phenomenon of switch failure, the author subsequently requested the professional and technical personnel to repair the fan inside of the cabinet, at the same time open to isolation switches, and Web server host, the host of such a switch as well as the Web server again, "fever," the chances of greatly decreased.
of K9 I-K switch failure phenomenon has been successfully ruled out, but I am wondering, why the switch,cisco valet router and Web server host "fever" so much? After careful investigation of the failure site. I found the switch and the Web server host where the cabinet, on top of four fans installed, and usually are surrounded by a closed cabinet, only four fans for cooling;
but do not know why, four fans can not work properly, so a lot of heat comes out of the switches, and Web server host to continue to work, it is not timely excluded from the cabinet, coupled with the close contact between the switch and the Web server host.
The heat that comes out will affect each other, eventually leading to a serious decline in the performance of their work. In order to solve the phenomenon of switch failure, the author subsequently requested the professional and technical personnel to repair the fan inside of the cabinet,cisco firewall router at the same time open to isolation switches, and Web server host, the host of such a switch as well as the Web server again, "fever," the chances of greatly decreased.
