Installation Test Procedures Issue 1, May 1986
2.01 General. This section describes the test equipment re-
quired to perform the installation test procedures, handling
precautions for Printed Circuit Boards (PCBs) with Metal Ox-
ide 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 equip-
ment 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 sta-
tion appearance can be used via the Main Distribu-
tion 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 qual-
ity 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.
WARNING
lirazardous voltages exist r&h.% the eqo&ment cabins?.
Be extremely careful when perr”orming fcsa-
incjtroubleshooting procedures with the oquipmcr;t
panel(s) removed.
2.04 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 o!)-
served when removing and rep!acing PCBs and powor SI:;X-
plies in an active sysicm.
2.05 lnifial Visual kspactizn Procedurx. The visu’al in-
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 allcw thorough inspection of the equipment.

SECTION 4.00 POWER-UP TESTS
4.01
General. The SATURN IIE System makes use of dis-
tributed power in the equipment cabinet. Several power sup-
plies 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 pow-
er cable assemblies are properly secured into their correspond-
ing locations. Note that the test procedures in Table 4.00 include
procedures for testing the optional MSM, when equipped in the
system.

‘CB in the system from its respec-
ive backplane connector in basic
md LTU shelves.
Check that all circuit breakers on the
‘SU are in the off positions and that
311 fuses are inserted in their cor-
,esponding locations.
Jsing the digital multimeter (or an
3c polarity indicator), verify that the
:ommercial ac power receptacle
Jsed for powering the systsm has the
Iroper polarity.
Connect the ac power cord(s) to the
zommercial ac power receptacle(s).

IF VERIFICATION
IS NOT 08TAlNED
if polarity indication does not coin-
cide, 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 af-
ter 30 minutes have elapsed. If green
LED remains extinguished, the bat-
tery pack is defective and requires
replacement.
