Telecom network structure now looks something like this: even come router to gather switches, switch to each panel
Due to individual so no enough room on the front panel, and then added five small switches connected to the panel on the front-end ports do use, there are three such small switches in use, there are two often can appear the problem of network, to restore network, after the Internet cable plug, what reason is this excuse me?

Check the cable connection order is correct, have inserted to the bottom, crystal head pressure in place,

check cable connection order is not correct, did exactly, crystal head pressure in place,

Is normal use after a period of time, there is no regular suddenly no network, small computer and yellow exclamation mark symbols, line should be pass

CodePudding user response:

There will be a kind of situation, connect the two small switch computers and even individual panel so the computer will no network at the same time, also will resume after the plug cables

CodePudding user response:

Do you mean the PBX is a small router? Is the function of DHCP, then your panel out of the line, it is inserted into the path of LAN mouth, cause the computer can't get the right IP address, so not on the net,

CodePudding user response:

Similar to figure in this, not the router

CodePudding user response:

Forward the data volume is too big? Small switches can't keep up with?

CodePudding user response:

This kind of problem in actual screening
Don't make should be no problem don't make don't make
Don't believe the yellow exclamation mark or prompt no internat network win sometimes brain-dead
All to personally check again

Pull out plug cable recovery
If a single point of failure line and the maximum module problems
Multipoint fault branch exchange overheating crash, loopback has not turned on the computer network card, network and so on caused by the superior switch failure

Do not rule out to pick up wifi routing caused by double DHCP problems
By sending and receiving of packets, and caught can be ruled out the problem, a can diagnose problems

CodePudding user response:

Superior switch failure will lead to part of the network no problem, part of a network failure
