160NOTE:Strictly follow the pinouts in the above tables when identifying or making the two types of Ethernetcables; otherwise, the communication quality may be affected.Connecting an Ethernet cable1. Connect one end of an Ethernet cable to an Ethernet interface on the module and the other endto the Ethernet interface on the peer device. Because the Ethernet interface of the modulesupports MDI/MDIX autosensing, you can use a straight-through cable or crossover cable toconnect the interface.2. Check the status of the LED of the Ethernet interface after power-on. For the status of the LED,see the relevant part in this manual.Fiber portAppearances and applicable models of transceiver modules and optical fibersOptical interfaces must work with SFP transceiver modules and optical fibers with LC connectors.Table 218 Ethernet cable appearance and applicable modelsCable Appearance Applicable models100-Mbps SFP transceivermoduleSIC-1FEFMIM-1POSMIM-1CPOSFIC-1POSFIC-1CPOSMIM-1ATM-OC3FIC-1ATM-OC3100-Mbps BIDI transceivermoduleSIC-1FEFMIM-1POSMIM-1CPOSFIC-1POSFIC-1CPOSMIM-1ATM-OC3FIC-1ATM-OC31000-Mbps SFP transceivermoduleSIC-1GECMIM-1GEFMIM-2GEFFIC-1GEFFIC-2GEF
