INSTALLATION 
1. 
PROCEDURES: Mount the two U-type fasteners contained in the Mounting Hardware Kit on the mounting 
flange hole openings where the -48PS module is to be installed. 
2. Lift and position the -48PS module over the mounting flange containing the U-type fasteners. 
Once in position, insert the remaining four screws with washers from the Mounting Hard- 
ware Kit through the front and rear hole openings and secure into position. 
3. For connections of power cable assemblies, refer to Section 5.00 in this practice for details 
on power/ground cabling. Before connecting the power cables, check that the associated cir- 
cuit breaker on the PSU panel is in the OFF position. 
4. After performing the above procedures, refer to the SATURN IIE EPABX Installation Test Proce- 
dures practice for further instructions to test the -48PS modules when powering up. 
Note: When the expansion cabinet is equipped, -48PSl module and a second AC power cord 
are required; remove J2 jumper plug from PSU.

4.06 Miscellaneous Equipment. The Floppy Disk Drives 
(FDDs) are data storage modules which use a 5- l/4 inch flop- 
py disk as the data storage medium. The double-sided, quad 
density, removable disk is not shipped with the FDD module and requires compliance with certain licensing agreements 
prior to its delivery. Refer to Table 4.12 for further details on 
the FDD modules.

FDD Module Assemblies V30141-ZO121-A6- * -N900 
DESCRIPTION The FDD module, shown in Figure 4.24, is a data storage device which uses a floppy disk (not in- 
: cluded) as the data storage medium. The double-sided, quad density, removable disk is capable 
of storing a minimum of 1.0 megabyte of formatted data. Two FDD modules are equipped in the 
system (FDDO and FDDl). The FDDs provide the backup memory for system initialization, system 
reload, administration, and maintenance testing. 
1. Indicators. One red LED located on the front panel which momentarily lights when a read/write 
function is being executed. 
2. Switches. One release switch lever on the front panel used for locking or releasing the floppy 
disk. 
3. Strapping Options. None. 
INSPECTION 
PROCEDURES: 
OBSERVATIONS: 
INSTALLATION 
PROCEDURES: None. 
1. When handling the FDD module, avoid finger contact with the contact heads. 
2. When handling the Common Control Feature Disk, avoid finger contact with its surface. 
3. Never attempt to close switch lever on the front panel unless a disk is inserted. 
The equipment cabinet comes equipped with two Floppy Disk Drive Modules when shipped from 
the factory. If replacement of a defective FDD is required, perform the following steps: 
1. Remove the seven screws securing the PSU front paneLand then remove four screws on 
the FDD retaining plate, disconnecting two connector plugs. Slide out the FDD from the mount- 
ing bracket and remove ground wire. 
2. To install a new FDD, perform the inspection procedures in steps a through f; and then install 
the FDD by following in reverse the procedures described in step 1. 
a. Place FDD on clean bench surface with the PCB on its side and its front panel facing 
checker. 
b. Manually rotate motor. Observe that the motor rotates freely and smoothly. 
c. Operate front panel release lever. Observe that carrier mechanism opens to insert flex- 
ible disk cartridge and that centering cone is released from spindle hub. 
d. Insert disk cartridge fully. Observe that spring-loaded latch is enaged and that disk 
cartridge is seated properly over drive mechanism. 
e. Rotate spindle drive mechanism. Observe smooth rotation of floppy disk. 
f. Do not close lever without disk or blank cartridge being inserted. 
3. For signal and power connections, refer to Section 5.00 in this practice for details on signal 
and power/ground cabling. 
4. Refer to the SATURN IIE EPABX Installation Test Procedures practice for further instructions 
before powering up.

Installation Procedures 
4.07 Printed Circuit Boards. The plug-in PCBs are 230mm 
(9.02 in.) high by 280mm (11.02 in.) deep. Each PC6 has two 
edge-connector tab areas with 60 terminals each. The PCBs 
plug into mating 60-pin connectors mounted on the backplanes 
of the basic and LTU shelves. Two extractor levers, mounted on 
the faceplate of each PCB, allow for easy insertion or removal 
from the shelf connectors. Each PCB comes factory-shipped in- 
side an anti-static bag to protect the MOS integrated circuits. 
Each bag is enclosed in foam material inside its carton as shown 
in Figure 4.26. 
CAUTION 
Craft personnel handling PCBs with MOS integrated circuits 
must first free themselves from electrostatic charge by 
touching the frame of an already grounded system cabinet 
or by wearing grounded wrist straps. Failure to observe this 
practice may result in damage to the PCBs due to elec- 
bvstafic discharge. 
There are two types of PCBs: peripheral interfacing PCBs and 
common equipment PCBs. The type of PCB may be readily 
identified because the peripheral PCBs have a notch separat- 
ing the two edge connectors and the common equipment PCBs 
do not. Refer to the following tables for further information on 
the peripheral interfacing PCBs and common equipment PCBs.

Table 4.13 Dual-Tone Multifrequency (DTMF) Receiver PCB (S30810-(2431-X2- * -B900) 
DESCRIPTION The DTMF PCB, shown in Figure 4.27, contains four circuits (0, 2, 4, and 6) utilizing four ports. Under 
no circumstances should more than three DTMF receiver cards be assigned on one shelf. This require- 
ment is a limitation of the power supply. Each circuit provides the means for dial tone detection and 
validation of DTMF tones. 
1. Indicators. There are four red LEDs (TRCO, TRC2, TRC4 and TRCG) on the faceplate of the PCB. 
Each LED indicates the following status conditions of one of the four assigned DTMF receiver 
Circuits: 
a. LED steadily lit - The associated DTMF receiver circuit is busy. 
b. LED extinguished - The associated DTMF receiver circuit is idle and in-service. The LED 
always remains extinguished for unassigned MMF receiver circuits. 
OBSERVATIONS: 
INSTALLATION 
PROCEDURES: c LED flashing - The associated MMF receiver circuit is idle and in an out-of-service state. 
2. Switches. None. 
3. Strapping Options. None. 
None. 
Locate in any channel group in the basic or LTU shelf for optimum port usage. Refer to Section 2.00 
of this practice for details.
