5 Appendix Testing the Connection of Assembled Cables Context Huawei provides two types of Ethernet cables: straight-through cables and crossover cables. Straight-through cables are connected in a one-to-one manner. They are used to connect terminals such as a computer or switch to network devices. Table 5-7 lists the connections of core wires in a straight-through cable.
For example, in this document, the adapters of cable connectors have separate interfaces. In the actual situation, the adapters may have interfaces fixed on equipment. Use dedicated tools provided or specified by Huawei and follow the installation procedure described here.
The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information. You are advised to use Huawei-certified optical modules. Obtain the electronic label of the optical module and contact Huawei technical support personnel to confirm whether it is a Huawei-certified optical module.
