2.1 Unpacking the Unit
Each 2200 Series Modem is shipped factory tested, and packed in a protective carton. Unpack
the unit and retain the shipping carton and protective packing for reuse in the event it is necessary
to return the modem to the factory.
To assure proper operation of the modem, please inspect it and its shipping carton carefully for
damage. If damage is sustained to the unit, immediately file a liability claim with the freight carrier.
Canoga Perkins is not liable for damage in shipment
2.2 Standalone Modem Installation
Installing the standalone version of the 2270 is straightforward. It should be located conveniently to
the operator. The electrical and optical cables should be isolated from foot traffic to prevent pos-
sible damage.
For AC-powered units, the attached power supply for the standalone is a wall-type transformer. It
should be plugged into a standard AC wall outlet that incorporates a ground line. A POWER ON
switch is not provided as the modem is powered when the unit is plugged in.
2.3 2202 Modem Shelf Installation
Two 2270 standalone modems may be installed in an equipment rack when using the 2202 Mo-
dem Shelf. The modems may be placed side-by-side on the shelf after the shelf is mounted in the
equipment rack (see Figure 2-1).
For a more secure assembly, two screws are provided to secure the modems to the shelf prior to
installing the shelf in the rack.
First, on the modem that will be mounted on the left side of the shelf, remove and discard the
center cover attachment screw on the left side. Position the modem so that the empty hole lines
up with the one on the left side of the shelf.
Next, using one of the longer screws provided, mount the modem from the outside by threading
the screw through the 2202 shelf and into the cover screw hole in the modem.
