Purpose. The equipment comprising the SATURN
IiE
(SATURN Ii-Expanded) System is
compleYely
tested at the factory prior to shipment. The inspections and tests covered in
this practice verify that the EPABX equipment has been
properly installed; ensure that no damage
wasIncurred
during transit; and confirm that the sysiem is completely operational. Table 1.00 defines the mnemonics usedthroughout
ihis
practice.
CAUTION

Siemer;s cetiified
personnel.

Sccpe.
This practice is
divided
into the following sec-
tions which are presented in the sequential order of
per-for-
mance
after initial installation of a SATURN

System. When
additional equipment is installed to an existing and active
SATURN

System, it is the responsibility of craft person-
nel to determine the sequential order of the test procedures
contained in
tihese
sections.

Installation Test Procedures Issue 1, May 1986
2.01
General. This section describes the test equipment required to perform the installation test procedures, handling
precautions for Printed Circuit Boards
(PCBs)
with Metal Oxide Semiconductor (MOS) integrated circuits, guidelines for
removal and replacement of
PCBs
and powei supplies, and
initial visual inspection procedures.
2.02 Test Equipment Required. The following test equipment is required to perform the procedures contained in this
practice:
a. Digital Multimeter. A digital multimeter of
gocd
com-
mercial quality with an accuracy of + 1.0% or better.
The digital multimeter is used to perform the ground
tests and output voltage tests.
b.
Maintenance Test Phone. For both Dial Pulse (DP) and
Dual Tone Multifrequency
(DTMF)
systems, a lineman’s
test set or a single line
te!ephone.
A modular jack
(MTCE PHONE) is provided on the front
panal
of the
PSU for
conneciing
the maintenance test phone when
equipped with a modular plug. When the maintenance
test phone is not equipped with a modular plug, a station appearance can be used via the Main Distribution Frame
(MDF).
The
mainienance
test phone is used
to perform the on-line diagnostic tests.
c. Data Service Terminal. A Keyboard-Send-Receive
(KSR) daia terminal equipped with a standard ASCII
keyboard and an EIA RS-232C interface (Silent 700
Series - Model 743 KSR - Texas Instruments, or
equivalent). The data service terminal is used to input
installation dependent data (i.e., system data base) into
system memory when the standard data base format
is supplied with the SATURN
IIE
System.
d. -Transmission Measuring Set. A transmission measur-
ing set (TMS) used to measure the transmission quality of a trunk or station (Hewlett Packard HP-355iA or
equivalent). Refer to the manual On-Line
DiagnostiC
Tests, Outgoing Trunk Test and Station Line
Tosl.
2.03 handling Precautions for
PCBs wifh MCS Integmt-
ed
Circuiklt
is important that craft personnel handling
FCBs
with MOS integrated circuits free themselves from electrostatic
charge by touching a grounded cabinet frame before handling
such
PCEs,
or by wearing grounded wrist straps.
Failur:,
to
observe this practice may result in damage to
MO3 PCBs
due to electrostatic discharge.

PCB Removal and
P,ep!acemenZ Guide%%
In many
instances during testing, the corrective action for a procedure
in which the proper verification was not obtained requires that
a PCB or a power supply be removed and replaced with a
spare.
Tablo
2.00 provides the guidelines that
shou!d
be

spection procedures contained in
Tab!e
2.01 must be
psrfcrmcd
to ensure that the equipment comprising the SATURN
ItE
Sys-
tem has been properly installed and configured to meet the
installation requirements. Before proceeding
wiih
the visual in-
spections, the front, rear and side panels of the
cabinei should
be removed to

General. The SATURN HE System must be connected
to an earth ground (i.e., metallic cold water pipe or master ground
busbar)
in addition to the safety ground in the ac power cord.
A
G-gauge
(twisted copper wire) conductor should be connected between the grounding lug E5 located on the bottom of the
cabinet frame and the
snlccted
earth ground (refer to Section
3.00 in the SATURN HE EPABX Installation Procedures practice for details). The following tests must be performed to en-
sure that proper earth ground connections have been
accomplished, and that ground connections within the cabinet
assembly have not been damaged or loosened during shipment.

SECTION 4.00 POWER-UP TESTS
4.01
General. The SATURN
IIE
System makes use of distributed power in the equipment cabinet. Several power supplies are used in the system. These power supplies provide
+5Vdc, -SVdc, +12Vdc, -12Vdc, -48Vdc, 90Vac-20Hz
ringing
voltage and message waiting voltage, from a
11OVac 60Hz
input power source. After satisfactorily performing the ground
tests
indicaied
in Section 3.00, the following
tests
must be per-
formed to ensure that proper power cable connections have
been accomplished and that the power supplies inside the
cabinet assembly have not been damaged during shipment.
WARNING
Hazardous
voltages exist within the equipment cabinet.
Be
extremely
careful
when performing
testin@roubkshootjng’
pmcedures
with the equipment panel(s) removed.
4.02
Power-Up/Output Voltage Tests. Before proceeding with
the test procedures indicated in Table 4.00, check that all power cable assemblies are properly secured into their corresponding locations. Note that the test procedures in Table 4.00 include
procedures for testing the optional MSM, when equipped in the
system.

VERIFICATION
‘olarity

if polarity indication does not coincide, correct before proceeding with
the remainder of test in this
lable.
If the green LED remains
cxtin-
guished, the battery pack is below
acceptable voltage limits. Let MSM
charge battery pack and retry test after 30 minutes have elapsed. If green
LED remains extinguished, the battery pack is defective and requires
replacement.
