Mda Slot; Console Port Connector - Bay Networks BayStack 303 User Manual

Using the BayStack 303 and 304 Ethernet Switches
A speed LED (100) is also provided to indicate when the port is operating as a
100 Mb/s port. The LED is off when the port is operating as a 10 Mb/s port. See
"Autonegotiation" on

Like the 10BASE-T ports, all 10/100BASE-T ports are also configured as MDI-X.

MDA Slot

Each BayStack switch is configured with one expansion slot that can be populated
with an optional plug-in media-dependent adapter (MDA) to support a high-speed
connection to servers, shared Fast Ethernet hubs, or backbone devices. Two types
of media adapters are available for the BayStack switches:
•
•
Both media types support half- and full-duplex operation and have an LED to
indicate when the port is operating in full-duplex mode. See
"Technical
Warning: Power to the switch must be turned off prior to installation of the
MDA.

Console Port Connector

The console port has a DB-9 male connector used to connect a management
terminal to the BayStack switch by means of a straight-through DB-9 to DB-9
standard serial port cable. Using a terminal, you can monitor the results of startup
self-diagnostics, perform manual boot configuration and SNMP agent
configuration, and customize your network using the supplied menus and screens.
The console port runs at 9600 baud and uses 8 data bits, 1 stop bit, and no parity
as the communications format, with flow control disabled.
In less complex applications with no network management, where no
configuration changes are required, you do not need to use the console port on the
BayStack switches.
