ports. This eliminates the
need for an insertion tool
during installation.
Status LEDs are powered
by the attaching Token Ring
adapters, and provide a visual

The MAU automatically
detects the removal of a cable
and wraps the Ring In or Ring
Out port—so there’s no

16-Port Type 3 MAU is
in the same way as
industry-standard IBM
8228 token ring MAU. It is a
wiring hub used to create a
star wiring configuration
from the main ring to
individual token ring
workstations. Like the IBM
8228 MAU, the 16-Port Type 3
MAU has Ring In and Ring
Out connections on the front
panel. However, it has 16
workstation ports, rather than
8, while using no additional

RJ-45 connectors that allow
the use of less-expensive UTP
cabling. The MAU has LEDs
for Port Status and Reset to

also has a reset button, which
is powered by an included
lithium battery and
eliminates the need for a
costly insertion tool.
