Page 12: Cabling
10 cabling twisted-pair segment can be use unshielded twisted pair (utp) or shielded twisted pair (stp) cabling. The cable must comply with the ieee 802.3u 100base tx standard for category 5. The cable between the converter and the link partner (switch, hub, workstation, etc.) must be less than 100 ...
Page 13: Troubles Shooting
11 troubles shooting check the configuration dip-switch. It must be setting in the same operation mode with the link partner. Select the proper utp/fiber cable to construct your network. The single-mode converter must use single-mode fiber cable. Please check that you are using the right cable..
