Do not assume laser power is turned off or the fiber is disconnected at the other end. Caution: Ethernet signals over copper should not be used between buildings. Ground potential differences may cause transmission errors or line card failures. 20460-A RJ45 CONNECTOR OPTICAL TRANSMIT OPTICAL RECEIVE ADCP-92-063 • Issue 1 • May 2005 b. The IEEE Standard ANSI/TIA-568-B for Ethernet 10/100BaseT(X) requires that two twisted pairs be used and that one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6. c. The IEEE Specification Standard ANSI/TIA-568-B for Ethernet 1000BaseT requires that four twisted pairs are used. One pair is connected to pins 1 and 2, pair two is connected to pins 3 and 6, pair three is connected to pins 4 and 5, and pair four is connected to pins 7 and 8. 9. Connect Ethernet RJ45 patchcord to RJ45 receptacle on the converter module. 10. Verify that the front panel LEDs are active. Link LEDs are not lighted if there is no Ethernet or optical signal present. PIN 1 PIN 8 11899-A Figure 5.

The POWER indicator (GREEN LED) on the converter module should light to indicate that VDC power is applied to the media converter. If POWER indicator does not come on, verify that power connections between the Media Converter Module and the power supply are secure. Verify that there is power present at the source. If this procedure does not resolve the problem, replace the cable or power supply. Page 10 © 2005, ADC Telecommunications, Inc. ADCP-92-063 • Issue 1 • May 2005 OptEnet Media Converter with SFP modules support Medium Dependent Interface Crossover (MDI-X). OptEnet Media Converter Module Ethernet ports allow connections to other hubs or switches without a null-modem or crossover cable. If a null-modem or crossover cable has been used the OptEnet Media Converter with SFP module automatically detects this and switches the contacts to match the other end. Any blinking of a link LED indicates auto-negotiation in process. If a link LED continues to blink for more than 30 seconds then the operation of the far end device (i.e., duplex and speed) needs to be verified or changed. 5.1 10/100 Mb/s Module If the PC workstation port has been set to auto-select (i.e., full auto-negotiation) for speed and duplex, the TPLink LED will be OFF when power is applied unless a valid optical link has already been established with a remote optical port. If a valid optical link has been established, FOLink LED will be YELLOW for 10 Mb/s operation or GREEN for 100 Mb/s operation. The preferred mode of operation for the port is auto select for both speed and duplex. This will insure that a link can be established regardless of the far end operational mode. OptEnet 10/100BaseLX Media Converters support auto-negotiation as defined in TIA/EIA-785. Auto-negotiation allows the unit to automatically select the highest performance level for COPPER or FIBER. 5.2 1000 Mb/s Module Set data rate speed to 1000 Mb/s and enable half/full duplex auto-negotiate on any equipment connected to the OptEnet 1000 Mb/s Media Converter module. If the Network Interface Card (NIC) or port in the PC workstation has been set to 10...
