Version v5.0 of pc network security isolation card integrates the functions of single hard disk and dual disk isolation card, and realizes the physical isolation function of single hard disk and dual disk isolation card respectively by adjusting the chip and card surface jumper.
Second, v5.0 version isolation card mode
Third, set the v5.0 version of the isolation card to the dual-disk state.
Version v5.0 dual-disk isolation card uses two hard disks, each with an operating system and different network configurations, which are used in two isolated networks. By controlling the data cable of computer hard disk, only one hard disk can be accessed and used at a time, so as to achieve the purpose of physical isolation.
Install and use v5.0 version of dual-disk isolation card.
1. Install their own operating systems and different network configurations on two hard disks to ensure the normal operation of the system and network;
2. Turn off the computer, turn on the chassis, and connect the main ide interface of the motherboard to the motherboard slot (blue slot) of the isolation card;
3. Connect the intranet hard disk to the intranet ide slot (internal slot) of the isolation card;
4. Connect the external hard disk to the external ide slot (external slot) of the isolation card;
5. Insert the isolation card into the idle pci slot of the motherboard and close the chassis;
6. Turn on the computer to enter the internal and external network selection menu, and choose whether to enter the internal network system or the external network system according to the prompt.
Fourth, set the v5.0 version of the isolation card as a single hard disk.
Version v5.0 single hard disk isolation card is suitable for hard disks over 40g. It is recommended to use Pentium iii and above models, and use our patented technology to divide a single hard disk of a computer into two independent hard disk partitions.
Data exchange area (optional): When installing, you can choose to set a data exchange area between the external network and the internal network. The data exchange area has read/write access to the external network area and only read-only access to the internal network area, forming a one-way data transmission channel from the external network to the internal network, which is absolutely safe and reliable.
1. Install the v5.0 release card.
(1) Turn off the computer, open the chassis, and insert the isolation card into the idle and normal pci slots of the computer;

Esk network security isolation platform -V5.0
Install intranet or extranet operating system.
1, enter the external network system.
2, enter the intranet system
3.ctrl+enter to confirm the installation.
(6) Repeat the above steps until the operating systems of the internal and external networks are installed;
(7) Start the intranet operating system and the extranet operating system respectively, confirm that the system is running normally, restart the computer, and select 3. Ctrl+enter to confirm the completion of the installation, and confirm that the installation has been completed. Screen tip:
Esk network security isolation platform -V5.0
Please enter the password:
Enter the password: china-esc.
(8) Restart the computer, and the screen prompts:
Cisco Network Security Isolation Platform-v5.0
1, enter the external network system.
2, enter the intranet system
When selecting 1 for the first time, enter the external network system and 2. When you enter the intranet system, you will be prompted to look for new hardware. Please follow the prompts to put the driver floppy disk that comes with the product into the floppy drive, select the driver source path A:], and then install the driver. (Drivers can be downloaded from company website resources)
(9) Version 9) v5.0 isolation card is installed.
Verb (abbreviation of verb) installs the network connection of v5.0 isolation card.
1, two-wire network environment:
(1) Connect the network jumper to the NIC port of the isolation card;
(2) Connect the internal network cable to the internal network port of the isolation card;
(3) Connect the external network cable to the external network outside the isolation card.
2, a single wiring network environment:
(1) Use the equipment network produced by Nanjing Esk Company to control isolation;
(2) Connect the network jumper (four cores) to the network card port of the isolation card;
(3) connecting the intranet server to the intranet port of the network control isolator;
(4) Connect the external network server to the external network port of the network control isolator.
(5) Connect the internal network port of the subscriber isolation card to the terminal port of the network control isolator.
See "Chapter 7 Instructions for Use of Network Isolation Controller". If the network isolation controller is not used and the single-wire network environment is transformed by direct branch, please contact the dealer and manufacturer.
3. The external network uses a modem to dial up the Internet. Please download the modem dial-up Internet scheme and jumper setting diagram from the company website, or contact the dealer and manufacturer.
Six, about the setting of v5.0 version isolation card exchange area.
The setting of the exchange area must be operated by a professional engineer, and the exchange area should be used correctly according to the engineer's tips. Users are not recommended to set it by themselves.
