In comparison to using two
8-port MAUs, the 16-port
MAU costs less. Also, you
only use half of the rack space
of common 8-port MAUs.
Since no AC power is

non-air-conditioned areas,
such as warehouses and
A long-life lithium battery
provides power to a circuit
that allows the manual reset of
all lobe circuits. You simply
press a button to reset the
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
indication of connect status.
The MAU automatically
detects the removal of a cable
and wraps the Ring In or Ring
Out port—so there’s no
network downtime!
Shielded RJ-45 connectors
on the lobe ports provide

Technically Speaking
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

rack space. The MAU has
RJ-45 connectors that allow
the use of less-expensive UTP
cabling. The MAU has LEDs
for Port Status and Reset to
give you status at a glance. It
also has a reset button, which
is powered by an included
lithium battery and
eliminates the need for a
costly insertion tool.
