130 Appendix A Metro Ethernet Routing Switch 8600 module technical specifications"Pin assignments: 8691omSF module Management port" (page 130) showsthe pin assignments for this connector.Pin assignments: 8691omSF module Management portConnector Pin number Signal1 Output transmit data + (TX+)2 Output transmit data - (TX-)3 Input receive data + (RX+)6 Input receive data - (RX-)4, 5, 7, 8 Not usedConsole serial portThe Console serial port is implemented as a DB-9 connector. This portcan operate as a data terminal equipment (DTE) or data communicationequipment (DCE) device. Use the switch to the left of the port to set the portto DTE (right) or DCE (left). Default settings for this port are 9600 bits/s, 8data bits, no parity, and one stop bit.Connection to TXD and RXD signals and GND is sufficient for the consoleserial port to fully function. The Console port does not support any inboundflow control; that is, the port does not toggle control lines to indicate an inputbuffer full condition."Pin assignments: 8691omSF module Console port" (page 130) lists the pinassignments for the Console port for both the DTE and DCE settings.Pin assignments: 8691omSF module Console portSwitch positionConnector Pin number DCE (left) DTE right)2 TXD (Output) RXD (Input)3 RXD (Input) TXD (Output)4 DSR (Input) DTR (Output)5 GND GND6 DTR (Output) DSR (Input)7 CTS (Input) RTS (Output)8 RTS (Output) CTS (Input)Modem serial portThe Modem serial port is implemented on a DB-9 connector wired as aDTE connection.Nortel Metro Ethernet Routing Switch 8600Installation — ModulesNN46220-306 02.02 Standard4.2 7 July 2008Copyright © 2005-2007, Nortel Networks.
