Making Connections to a Hub
Each Hub has II modular (RJ45) jacks and one AUt port. The
jacks labeled' '2" through' 'II " are permanently configured as IN
jacks, and the jack labeled' 'I " is a switchable IN/OUT jack.
This section describes how to make connections to a Hub in a room
or a wiring closet to form a StarLAN 10 Network. Before making
any connections to a Hub or any other StarLAN 10 Network
device, you should read the "General Connection Rules" section
that follows.
Once you have completed making connections to the Hub, test the
network traffic movement through the Hub by following the
procedure in "Verifying Connections to the Hub" later in this
guide.
General Connection Rules
The following connection rules apply to all StarLAN 10 Network
configurations:
When you connect a transceiver (AUI) cable to a Hub's AUI
port, you must connect the DCE D-type male connector of the
transceiver cable to the DTE D-type female connector on the
Hub.
When connecting two devices together using twisted-pair wire,
you must connect the OUT jack of one device to the IN jack of
the other device.
Certain StarLAN 10 Network hardware devices (such as the
Hub, the Coax Adapter, the Fiber Hub, and the Fiber Adapter)
have switchable IN/OUT jacks. When connecting a modular
cord to an IN/OUT jack, you must check the position of the
IN/OUT switch to verify that the IN to OUT connection rule is
obeyed.
