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.
