Nortel Networks 350 manual Comm Port, Uplink/Expansion Slot, 10BASE-T/100BASE-TX Port Connectors

BayStack 350 10/100/1000 Series Switches

Comm Port

The Comm Port (also referred to as the Console/Comm Port) allows you to access the console interface (CI) screens and customize your network using the supplied menus 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 can use this connector to connect a management station or console/terminal to the switch by using a straight-through DB-9 to DB-9 standard serial port cable (see “Connecting the Console/Comm Port” on page 2-10).

Note: The Console/Comm Port is configured as a data communications equipment (DCE) connector. Ensure that your RS-232 cable pinouts are configured for DCE connections (see “DB-9 (RS-232-D) Console/Comm Port Connector” on page D-5).

The console port runs at 9600 baud and uses eight data bits, one stop bit, and no parity as the communications format, with flow control set to disabled.

Uplink/Expansion Slot

The Uplink/Expansion slot allows you to attach optional media dependent adapters (MDAs) that support a range of media types (see Appendix B, “Media Dependent Adapters” for more information about MDA types available from Bay Networks).

10BASE-T/100BASE-TX Port Connectors

BayStack 350 switches use 10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.

Note: The RJ-45 port connectors on BayStack 450 switches manufactured prior to December 1998 are numbered 1 to 12 and 13 to 24, in succession from left to right. Later units use port connectors that are configured with one or two dual, six-port groups, numbered 1 to 12 and 13 to 24. The top rows are odd numbered and the bottom rows are even numbered (see Figure 1-2 on

page 1-2). Port-specific examples in this guide show the appropriate port connections when required; other examples apply to both versions.
