About the McBasic 10/100 Module
The McBasic 10/100 module is a low-cost, standalone, IEEE 802.3 single-
conversion media converter which converts between:
10Base-T twisted pair and 10Base-FL multi-mode or single-mode fiber
100Base-TX twisted pair and 100Base-SX multi-mode fiber or 100Base-FX
single-mode fiber
The McBasic 10/100 is a 1U high, standalone unit that includes diagnostic LEDs
for each port and an internal, universal (100/240 VAC) power supply.
In many networks, the media converter is typically installed as a pair, between
two copper-based end devices. The McBasic 10/100 can also be installed as a
single media converter, between one copper-based device and the other a fiber-
based device. However, when connected to certain fiber-based devices, there
may be difficulty in the installation: if a link partner that is connected to the
McBasic media converter is powered down on the copper port, noise on the
copper segment may be detected and transferred to the fiber line. A result of
the noise will generate errors that look like CRC errors. Some fiber-based devices
many detect this noise and disable the fiber segment.
