2 Installation
Overview
This chapter describes the installation of the DeskTop T1 DSU.
The DeskTop T1 DSU is shipped pre-assembled, tested, and ready to
use. The normal procedure after unpacking the unit is to connect it to
ac power and perfom the Preoperational Check described in this
chapter. When the test is successfully completed you may proceed to
make cable connections to the DSU.
The DeskTop T1 DSU should be installed in a ventilated area where
the ambient temperature does not exceed 122°F (50°C). Do not install
the DSU above other equipment that generates large amounts of heat
(e.g., power supplies).
This chapter includes information on setting configuration options for
the DSU by means of the hardware switchbanks located on the pc
board.
Unpacking and Handling
The DeskTop T1 DSU is shipped in packing material that is enclosed
in a corrugated box. Inspect the DeskTop T1 DSU when you receive
it. If you observe any damage, notify the shipper immediately.
Do not discard the box and packing material. Save them for use if it is
ever necessary to reship the DeskTop T1 DSU.
Preoperational Check
You should give the DeskTop T1 DSU a preoperational check before
you connect it to the network or customer equipment, and before you
change any factory-set options. The factory default setting for all
options is all switches set to Off. Perform a Local Test with Self-Test
to verify normal operation. Refer to Chapter 4 for instructions on
performing the test. Perform the test on the DeskTop T1 DSU before
you connect it to anything other than ac power.
