3.1. Introduction
In addition to this manual, your Switch package
should contain one standard switch unit and a
wallmounted power supply. After you’ve unpacked
the Switch, take a few minutes to look through this
manual. You will need a screwdriver large enough to
remove the case screws, and a small screwdriver or
other edged tool for setting DIP switches. Also, you
might want to refer to the manuals of the devices
you plan to connect to the COS-II.
Installing the COS-II is a simple, three-step task
that should take no more than an hour to
complete. First, you’ll configure all of the DIP
switches for the internal options of the COS II.
Then, you’ll specify DTE or DCE for each port by
setting shunt jumpers. Finally, you’ll cable the
Switch to your devices and connect power to the
COS II.
3.2. Setting the DIP switches
In order to set the DIP switches, you’ll need to open
the case of the COS-II. There are several screws on
each side. Remove them, and lift the case lid from
the body of the COS-II. The board layout of your
unit should match the diagram shown below
(Fig.1).
