BayStack 450 10/100/1000 Series Switches302401-D Rev 00 1-3Comm PortThe Comm Port (also referred to as the Console/Comm Port) allows you to accessthe console interface (CI) screens and customize your network using the suppliedmenus and screens (see Chapter 3, “Using the Console Interface”).The Console/Comm Port is a DB-9, RS-232-D male serial port connector. You canuse this connector to connect a management station or console/terminal to theswitch by using a straight-through DB-9 to DB-9 standard serial port cable (see“Console/Comm Port” on page 2-10).The console port default settings are: 9600 baud with eight data bits, one stop bit,and no parity as the communications format, with flow control set to disabled.Uplink/Expansion SlotThe Uplink/Expansion slot allows you to attach optional media dependentadapters (MDAs) that support a range of media types (see Appendix C, “MediaDependent Adapters” for more information about MDA types available fromNortel Networks).Port Connectors10BASE-T/100BASE-TX PortsThe BayStack 450-24T switch and the BayStack 450-12T switch use10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.Note: The Console/Comm Port is configured as a data communicationsequipment (DCE) connector. Ensure that your RS-232 cable pinouts areconfigured for DCE connections (see “DB-9 (RS-232-D) Console/Comm PortConnector” on page E-5).Note: The RJ-45 port connectors on BayStack 450 switches manufacturedprior to December 1998 are numbered 1 to 12 and 13 to 24, in succession fromleft to right. Later units use port connectors that are configured with one or twodual, six-port groups, numbered 1 to 12 and 13 to 24. The top rows are oddnumbered and the bottom rows are even numbered (see Figure 1-2 onpage 1-2). Port-specific examples in this guide show the appropriate portconnections when required; other examples apply to both versions.kombk.book Page 3 Tuesday, June 29, 1999 3:25 PM
