INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek SR-20 sub-rack. Please take a few minutes to
read these installation instructions in order to obtain the maximum performance from this
product.

FUNCTIONAL DESCRIPTION

The SR-20 sub-rack is a standard 19" x 5.25" frame designed to accommodate up to fourteen
fiber optic plug-in cards along with a PSR-2 power supply.

SYSTEM COMPATIBILITY

Any plug in card with the model number beginning with the letter "R" can be inserted into any of
the fourteen application slots on the left-hand side of the SR-20.

INSTALLATION

THIS INSTALLATION OF THIS UNIT SHOULD BE MADE BY A QUALIFIED SERVICE
PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.

The SR-20 may be mounted, using standard hardware, in an upright position, with the
backplane upward, inside a standard 19” EIA rack cabinet. It is important, as with any electronic
equipment, to provide sufficient airflow to prevent over heating in the cabinet. At least 1 3/4"
(1RU) of space should be allowed above and below the SR-20 to provide air flow. If more than
one SR-20 racks are installed, forced airflow may be necessary depending upon the number of
plug-in cards used in the over-all installation. It is necessary to add a 1RU fan unit at the top of
every three SR-20 sub-racks with 1RU spacing between them.

The far right hand position of the SR-20 is only compatible with a PSR-2 series plug in power
supply. Please refer to PSR-2 instruction manual for further information. Standard American
Fibertek rack card modems can be installed into any of the remaining slots. Insert the card all
the way until the edge fingers meet the internal bus connector and the front panel is even with
the front of the sub-rack. Then secure the ¼ turn fasteners by pushing with a small screwdriver,
turning the screw 90 degrees clockwise and releasing pressure. Any card may be used in any
open slot.
