Tips for selecting dummy load company are:

1, the function test of the port: the main test is whether each port can work normally in the duplex state of 10Mbps, 100Mbps, and half duplex state. At the same time, it should be tested whether each port can automatically select a high transmission speed and automatically match the transmission rate of other devices.

2. Compatibility test: Mainly test the connection ability between dummy load company and other different devices compatible with Ethernet and fast Ethernet (including network cards, hubs, switches, optical network cards, optical switches). Requirements must be able to support connections to compatible products.

3, cable connection characteristics: First of all, the connection capability of five types of network cables with lengths of 100m and 10m should be tested, and the connection capability of five types of network cables (120m) of different dummy load company brands should be tested. During the test, the transceiver photoelectric port is required to have a connection capability of 10Mbps and 100Mbps rate, and the high must be able to connect to full-duplex 100Mbps 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 optical port of dummy load company transmits different packets, and the connection speed under different connection rates. You can use the test software of the network adapter to test the packet loss rate. You should test the packet loss when the packet size is 64,512,1518,128 (optional)1000(optional) bytes at different connection rates, the number of packet errors, and the number of packets sent and received must be more than 2,000,000. Test transmission speed can use perform3, ping and other software.

5. The compatibility of the whole machine with the transmission network protocol: The main test is dummy load company's compatibility with network protocols. It can be tested under 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. The dummy load company is required to support these protocols (VLAN, QOS, COS, etc.).

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

7, measure the after-sales service of the manufacturer, imagine, if your equipment is broken, the manufacturer has not solved the problem for a few days, how much is your loss? Therefore, in order to make after-sales service timely and early response, it is recommended that you choose the brand company with strong strength, high technical force and good reputation in the region. Only the company's technical engineers have rich experience in troubleshooting, and the tools for detecting faults are more advanced!
