LOBE ACCESS UNIT
want the unit to work in a standalone environment,
change the switch to the TAU position; otherwise,
leave it in the LAU position (which is the factory
default).
3.3 Electrical Installation
The Lobe Access Unit does not require any external
power; only data cables should be connected to the
unit. LT0009A uses Type 1 cables, and LT0009A-UTP
uses Type 3 cables. Use the steps below to install the
unit in the token ring.
1. Connect the unit’s MAIN port to your MAU’s
LOBE port. Note that if you’re using the Lobe
Access Unit in a standalone mode, this step is not
necessary since the MAIN port is unused.
2. Attach the workstations’ token-ring cards to the
SUB-1 through SUB-4 ports. Some ports can be
left unused if you have fewer than four
workstations.
3. Load the drivers for the token-ring card in the
workstation. The workstation should insert into
the ring. The LED on the corresponding sub-port
of the Lobe Access Unit will light, and a clicking
should be heard.
Cable distances will vary depending on existing ring
