The selection of dummy load company skills are:

1. Port function test: Mainly test whether each port can work normally in the duplex state of 10Mbps, 100Mbps and half duplex state. Each port should also be tested to see if it can automatically select high transmission speeds and automatically match the transmission rates of other devices.

2. Compatibility test: Mainly tests dummy load company's connection ability with other devices compatible with Ethernet and fast Ethernet (including network cards, hubs, switches, optical network cards and optical switches). The requirement must be able to support the connection of compatible products.

3. Cable connection characteristics: First, the connection capacity of five types of network cables with lengths of 100m and 10m should be tested, and the connection capacity of five types of network cables (120m) of different dummy load company brands should be tested. During the test, the photoelectric port of the transceiver must be connected at the rate of 10 Mbit/S and 100 Mbit/s. The high port must be able to connect to the full-duplex 100 Mbit/s without transmission errors.

4. Transmission characteristics (transmission loss rate and transmission speed of packets of different lengths) : The main test is the packet loss rate when the photoelectric port of dummy load company transmits different packets, and the connection speed under different connection rates. You can use the test software delivered with the network adapter to test the packet loss rate. If the packet size is 64,512,1518,128 (optional)1000(optional) bytes at different connection rates, test the packet loss rate. The number of packet errors and the number of packets sent and received must be greater than 2,000,000. Test transmission speed can use perform3, ping and other software.

5. The compatibility of the machine to the transmission network protocol: The purpose is to test dummy load company's compatibility with network protocols. It can be tested in Novell, Windows and other environments. The following low-level network protocols, such as TCP/IP, IPX, NETBIOS and DHCP, must be tested to test the protocols that need to be broadcast. dummy load company is required to support these protocols (VLAN, QOS, COS, etc.).

6. Indicator state test: Test whether the state of the indicator is consistent with the description of the panel and user manual, and whether it is consistent with the current state of dummy load company.

7, Measure the manufacturer's after-sales service, just imagine, if your equipment broke, the manufacturer did not solve the problem for a few days, how much is your loss? Therefore, in order to make the after-sales service can be timely and early response, it is recommended that you choose when the region has the strength, high technical force, good reputation of the brand company. Only the company's technical engineers troubleshooting experience is more rich, detection of fault tools more advanced!
