When use, the high speed network transmission channel that lower part body 5 connects is compressed for testing derived EVE-NG
Packet, classification high-speed transfer and storage on server, and download from server high speed import EVE-NG test compressed package to
It is tested in EVE-NG virtual platform, is also convenient for uploading in VMware virtual machine snapshot to server.
When upgrading, side heat dissipation door-plate 6, the exented memory slot 12 matched by built-in computer host 11 are opened
Internally deposit into row upgrade expanding, the heat matched by built-in computer host 11 dial slotting high speed hard-disk interface 13 to hard-disc storage into
Row upgrade expanding, cooperation network attack and guard technology quickly grow update and the liter of bring Network Security Teaching experiment content
Grade.
And when placing, because side heat dissipation door-plate 6 has good anti-mosquito functions, so that when in use more
Increase effect.And side heat dissipation door-plate 6 is by right angle stopper 61, rotation jack-post 62, heat dissipation hole 63, closure door lock 64 and gold
Belong to door-plate 65 to be formed, it, will be by heat dissipation hole in this way when mosquito is entered by the heat dissipation hole 63 of metal panels 65
The right angle stopper 61 of 63 rear sides stops, and right angle stopper 61 and 65 gap of metal panels are smaller, so that mosquito is not easily accessible,
To which mosquito is turned one's head, so when in use, mosquito is effectively avoided to enter the damage to inner body.And side heat dissipation door
Plate 6 and maintenance heat dissipation door-plate 8 are using identical mosquito-proof mode, so that mosquito is directly entered when avoiding placing, so that improving meter
The service life of calculation machine network security course teaching computer.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
