Chapter Ⅰ Introduction

Product introductions

The 8/16-port USB rack-mountable KVM multi-computer switch is a multi- functional device that allows administrators to access an 8/16 HDMI computer from a set of USB keyboards, mice, or a set of keyboards, mice, and consoles.
There are four convenient ways provided to switch the computers in the installation architecture: (1) use the connection port selection button on the front panel of the switch; (2) input the hot key combination from the keyboard; (3) select from the on-screen display (OSD) menu. The Auto Scan function provides automatic scanning and monitors the computers in the installation architecture one by one. (4) The remote network control operation is carried out through the network port of the extended IP module to connect to the computer on KVM.
This product is very quick and easy to install. Simply connect the connection cable to the appropriate connection port. No software settings are required, no complicated installation procedures, and there will be no incompatible problems. Because the device can directly obtain the input data of the keyboard, it can operate on a variety of operating platforms (compatible with PC, Mac, Sun, etc.).
Since it is allowed to manage the computer connected to it from a single console, the installation of a set of KVMs (1) can eliminate the expense of purchasing individual keyboard, monitor and mouse for each computer; (2) saves space occupied by the extra devices; (3) saves energy costs; (4) avoids the inconvenience and waste of moving back and forth between computers; (5) rapidly upgrades to the remote network control mode of the IP control mode.

Parts

Front view

switching port, users can gently press the button of the corresponding serial number. In this way, they can switch the corresponding port to the current operation port. At the same time, they will hear the tweet of the internal buzzer of the device. Then they can confirm that the switching action has been executed correctly. And the embedded LED indicators of the selected port will also illuminate.
2| Embedded LED indicators| Each button has two LED indicators embedded inside it. Users can judge the current working condition and usage of the device according to the LED indicators embedded inside the button.

• Corresponding to the [ON] position is a red LED, indicating the online indicator, which means that the port is connected to a server computer device being used. If the [ON] LED indicator is not on, it means that no computer is connected to the corresponding port of the serial number or the connected computer is already closed.
• Corresponding to the [Select] position is a green LED, indicating the selection port indicator, which means that the server computer of the currently selected serial number can be operated. If the [Select] LED indicator is not on, it means that the server computer of the serial number port is not selected, and it is not the computer currently operated.

3| Device reset button| It is in the small round hole above the text marked [RESET]. In order to reduce the device restart caused by user’s incorrect operation, the product uses the embedded reset button. The user can insert a needle-shaped object into the round hole as needed for 1-3 seconds to complete the reset operation of the KVM device.
