Using the Passport 8100 ModulesC-4 204515-CTable C-2 describes the 1000BASE-LX MDA LEDs.8100-4TX MDAThe 8100-4TX MDA (Figure C-3) uses standard RJ-45 connectors to attachEthernet devices. This MDA can operate at either 10 Mb/s or 100 Mb/s speed.The speed is determined through autonegotiation with the connected device.Figure C-3. 8100-4TX MDA Front PanelTable C-2. 1000BASE-LX MDA LEDsLabel Type Color/State MeaningLink Communicationlink LEDsGreen/On A valid communication link is established.Green/BlinkingThe corresponding port is management disabled.Off The communication link connection is bad, or there is noconnection to this port.Phy Select Phy selectionLEDsGreen/On The corresponding Phy port is selected.Off The corresponding Phy port is in backup mode.Activity Port activityLEDsGreen/BlinkingIndicates network activity level for the corresponding port.A high level of network activity can cause LEDs to appearto be on continuously.8100-4TX MDAActivity10010F Dx9215EB2 11 = LEDs2 = 10BASE-T/100BASE-TX Port Connectors
