Improved switch design

① Fault tolerance capability of Power Supply

The redundant power supply equipment used for power backup can only be found on the advanced core network equipment. If you want to add a second set of backup power supply for the middle and low end network equipment, will require another non-fei fee relative to the price of the device itself ). The second-layer network management switch and above provide unique redundant power supply modules. In addition to the extremely low price, the physical size is also very small, similar to the general laptop external power supply module, do not need to occupy the user's valuable Rack Space, for enterprise data centers, you do not have to rent additional space to place backup power modules, which saves considerable costs.

② Replaceable fan modules

To make it easier for network administrators to manage and maintain networks, the fan system of the equipment is generally designed as a fixed module of the system, however, the fan module has the shortest life compared to other components of the switch. Once the switch is stopped or the rotation speed is reduced, the operation and service life of the entire switching system will be affected. It is very troublesome to repair the device only because of the fan. At this time, the design of a fan module that can be replaced by manually rotating two screws is very reasonable.

③ Added a USB interface to replace RS232 interface management

With the development of IT technology, the USB interface standard has gradually replaced the old RS232 interface. Currently, most network devices only configure the old RS232 serial interface for network management and monitoring. This makes the network administrators who often use laptops have a headache, because it has been difficult to find the 15-pin interface on the laptops on the market in the past two years. With the addition of a USB interface design, network administrators are provided with additional options to keep switching devices updated.

④ Built-in Cable Testing System

Built-in cable test function VCT (Virtual cable Test System) based on TDR (time domain reflection) technology ). You only need to use two buttons on the panel to test the port cable of a device and display the result with the most intuitive LED array. This allows you to determine the accurate fault point of the network cable. If you use the same PC or server with the same VCT function, you can completely solve the network cable faults that are a headache for network administrators.
