OVERVIEW
Need additional twisted-pair Type 3 ports in your Token
Ring LAN? Choose the 16-Port Type 3 MAU. It functions as a
wiring hub, so you can create a star wiring configuration from
the main ring to individual Token Ring workstations.
Like the IBM 8228 MAUs, this MAU features Ring In (RI)
and Ring Out (RO) connections on the front panel.
This MAU provides up to 16 additional ports for highdensity applications and does so without the need for AC
power and the use of a costly insertion tool for installation.
Since no AC power is required, the MAU provides flexibility
when deciding where to locate the wiring installation, which
may include non-air-conditioned areas, such as warehouses
and closets.
A long-life lithium battery provides power to a circuit that
allows the manual reset of all lobe circuits. 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 cable removal and wraps
the RI or RO port, so there’s no network downtime!
Shielded RJ-45 connectors on the lobe ports provide
support for UTP or STP 100-ohm cable. Use UTP cabling for
