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”).

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
“Console/Comm Port” on page 2-10).

The console port default settings are: 9600 baud with 8 data bits, 1 stop bit, and no
parity as the communications format, with Flow control set to Xon/Xoff.

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

10BASE-T/100BASE-TX Ports
Your BayStack 450-24T and BayStack 450-12T switches use
10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.
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 F-5).

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 1-3). Port-specific examples in this guide show the appropriate port
connections when required; other examples apply to both versions.
