3.9. Connecting and Powering Up the COS-II
Once you have configured the internal switches and
jumpers, you can connect your devices and the
wallmounted power jack to the COS-II. Before you
begin, you might wish to check the settings of all
the DIP switches again, to make sure you have set
them correctly.
To prepare the COS-II:
1. Make sure that SWA 8 is set to OFF, that is, to
normal operation.
2. Insert the 4-pin power-supply plug in the power-
supply socket (at J1) on the COS-II circuit board.
3. Slide the cover back onto the base of the COS-II,
and secure it with the screws.
4. Connect the device cables to the ports.
5. Plug the wallmounted power supply into a
standard AC line.
Before you use the COS-II, you might wish to
familiarize yourself with the indicators, reset button,
and self-tests available. Chapter 4 explains these
features.
