Hardware articles
1. As shown in the figure below, the product port is rich in various forms, with 24 full Gigabit standard POE power ports, 4 Gigabit SFP interfaces, 1 serial port (management port), 1 reset button (support hardware restart, restore factory Value), dynamic LED indicator, the working status of the device is clear at a glance, convenient and practical.
2.Front view, design attention to detail, LED dynamic display, Gigabit POE , fiber optic port in turn, orderly.
3.Left side view, the left side is mainly the air inlet of the device. It adopts a 2-stage design to separate the heat dissipation of the main board from the heat dissipation of the power supply. In addition, the upper and lower covers adopt a press-fit process, and the surface is flat, giving a visual aesthetic.
4. In the right side view, the right side is mainly the air outlet of the equipment fan. Three fans are used to pump out the hot air in the equipment. Therefore, when installing, please pay special attention to the air inlet and outlet air outlets. Ventilation is good for heat dissipation.
5. Back view, look for highlights? What is the difference between other factory? The press-fit mold is used to integrate the upper and lower covers, the surface is flat, high value, simple and beautiful.
6. Remove the upper cover, see the layout inside the device, the layout is neat, use the principle of air duct cooling, separate the main board from the power supply, separate heat dissipation, solve the problem of high-power power supply and POE heat dissipation; the power supply part uses dual output isolation power supply The network part and the PoE power supply do not share the same, each work, do not interfere with each other.
Core solution: Realtek and Maxim
7. The hardware comes at the end of the family, the accessories are complete,
(1) There are mounting brackets that can be installed in standard 1U cabinets;
(2) equipped with a serial cable to support direct connection between the computer and the device, and configure the switch through the command line;
(3) equipped with an AC power cord;
(4) equipped with quick instructions and CD software manual.
Software piece
