Appendix B
Media Dependent Adapters (MDAs)
The BayStack 303 and 304 Ethernet Switches come with an optional 100 Mb/s
port. To use this port, a media dependent adapter (MDA) is inserted in the switch
through the front panel.
The media adapter slot accepts either a 100BASE-TX (UTP) or 100BASE-FX
(fiber) media adapter to provide a switched Fast Ethernet link to high-speed
servers, switches, hubs, or routers. MDA installation instructions are contained in
Installing the BayStack 303 and 304 Ethernet Switch Media Adapters.,“ (Bay
Networks part number 893-01023-A).
This appendix describes the MDA types available.
100BASE-FX MDA
The 100BASE-FX MDA is used to attach a fiber-based 100 Mb/s connection to
the switch. The 100BASE-FX media adapter shown in
Figure B-1 can be used to
provide a direct attachment to end stations, switches, or servers where multimode
fiber is installed. This adapter accepts standard SC connections using
62.5/125-
µ
m fiber optic cable. The 100BASE-FX MDA is not supported on
single-mode fiber cabling. A link LED indicates when there is a valid link
connection, and a mode LED indicates when the port is operating in full- or
half-duplex mode (200 Mb/s or 100 Mb/s).
