chassis. (Refer to Figure 3-30 on page 3-49.) 
D. CONNECT THE TWO CABINETS 
TOGETHER 
6.11 
To install an expansion cabinet underneath the 
main equipment cabinet and connect the two together, 
perform the following steps: 
(1) If not already done, remove the front door and 
back panel from the main equipment cabinet as 
outlined on page 3-39. 
(2) Screw the four lifting handles into the holes pro- 
vided on the main equipment cabinet (as shown 
below). 
(3) With one person at each comer, carefully lift the 
main equipment cabinet up and place it securely 
on top of the expansion cabinet. 
A fully loaded equipment cabinet can weigh sever- 
al hundred pounds. To avoid injury, use proper lift- 
ing technique and exercise extreme caution. (4) At each of the four comers, use a y4-20 
X 
J&inch bolt and a star washer to secure the main 
equipment cabinet to the expansion cabinet (as 
shown below). 
;: 
(5) Route the free end of the expansion power cable 
(withthefivelargeconnectors)upthebackofthe 
equipment cabinet, in through the soffit (cable 
shelf), and out to the front of the cabinet. 
(6) Connect one end of the V-ring power cable to the 
appropriate connector on the front side of the 
main power supply chassis. (Refer to Figure 
3-30 on page 3-49.) 
(7) While sliding the expansion power supply chas- 
sis into place (the bottom edge of the chassis fits 
under a metal lip that is to the left of the main 
chassis), connect the free end of the V-ring power 
cable to the appropriate connector on the front 
side of the 
expansion power supply chassis. (Re- 
fer to Figure 3-31 on page 3-50.) 
(8) Using three, 8-32 
x @rich screws with wash- 
ers, secure the bottom of the expansion power 
supply chassis to the equipment cabinet. 
(9) Reaching in through the front of the cabinet, at- 
tach the five large connectors on the end of the 
expansion power cable to the appropriate con- 
nectors on the expansion power supply chassis.

E. INSTALL TECE POWER SUPPLY 
MODULES 
CAUTION 
HIGH VOLZdGE. When the system power is 
turned on, each module contains both 35OVDC and 
11OVAC. Before inserting or removing the power 
supply modules, make sure that the AC POWER 
switch has been turned OFF for at least five 
min- 
utes. Failure to allow the high voltage to dissipate 
can cause bodily injury. 
6.12 After the main power supply chassis and, if nec- 
essary, the expansion power supply chassis have been 
installed (as outlined on page 3-4S), install the power 
supply modules as follows: 
NOTE: Refer to pages 2-10 and 2-11 in SPECIFICA- 
TIONS for information concerning module compatibil- 
ities and special Tl requirements. 
(1) On each power supply, ensure that the AC power 
cable is not plugged in and the AC POWER 
switch is OFF. 
(2) At the rear of the cabinet, remove the screws to 
the back cover(s) of the power supply chassis, 
and set the cover(s) aside. 
NOTE: For easier power supply module remov- 
al, each version C power supply chassis is 
shipped with an extractor tool attached to the in- 
side of the back cover. The extractor tool may be 
used with version B and C modules only. 
(3) With the components facing right, insert the 
power supply modules in the appropriate slots. 
(Refer to Figures 3-32 and 3-33 on the following 
pages for slot locations.) Note the following re- 
quirements: 
CAUTION 
When inserting the power supply modules, be sure 
that each module is fully seated in the appropriate 
slot. If a module is not securely seated when power 
is turned on, the power supply and circuit cards 
may be damaged. 
l The main power supply chassis must be 
equipped with two Quad Modules, one Mas- 
ter 30V Module, one -48V Module, and one 
Ring Generator Module. 
l If an expansion power supply chassis is in- 
stalled, it must be equipped with one Quad 
Module and one Master 30V Module. 
l Depending on the number and type of keysets 
to be connected to Keyset Cards (DKSCs, 1 
KSCs, or KSC-Ds) in the main equipment 
cabinet, one or two Slave 30V Modules may 
also be needed in the main power supply 
chassis (see page 2-10 for details). 
l Depending on the number and type of keysets 
to be connected to Keyset Cards in the expan- 
sion cabinet, one or two Slave 30V Modules 
may also be needed in the expansion power 
supply chassis (see page 2-10 for details). 
l If any Single-Line Cards (SLCs), Inward 
Dialing Cards (IDCs), Loop/Ground Start 
Cards (LGCs), or E&M Cards (EMCs) are to 
be installed in the expansion cabinet, a -48V 
Module must also be installed in the expan- 
sion power supply chassis. 
NOTE: Loop Start Cards (LSCs) and Tl 
Cards (‘TlCs) do not require a -48V Module. 
(4) Slide the back cover(s) of the power supply chas- 
sis into place and replace the screws. 
II Always replace the back cover before tummg on 
(5) Plug the AC power cable on the 
expansion power 
supply chassis into the AC expansion receptacle 
on the 
main power supply chassis. 
NOTE: DO 
NOT plug in the system AC power 
cable until the power supply electrical test, as 
outlined on page 3-55, has been performed. 
(6) Ground the system according to the instructions 
on page 3-54. 
CAUTION 
To prevent damage, do not move the equipment 
cabinet any great distance while the power supply 
modules are installed.

Grounding Requinzments 
6.13 
The equipment cabinet must be properly 
grounded to an earth ground point. Acopper, cold water 
pipe is usually a good ground point 
NOTE: According to UL 1459, “an insulated grounding 
conductor that is not smaller in size and equivalent in in- 
sulation material and thickness to the grounded and un- 
grounded branch-circuit supply conductors, except that 
it is green with or without one or more yellow stripes, is 
to be installed as part of the circuit that supplies the 
product or system.” Also, “the attachment-plug recep 
tacles in the vicinity of the product or system are all to be 
of a grounding type, and the grounding conductors serv- 
ing these receptacles are to be connected to earthground 
at the service equipment.” 
6.14 The grounding wire should be 1OAWG or larger 
and should not exceed 25 feet (7.5 meters) to help pro- 
vide RFI/EMI protection, or should not exceed 10 feet 
(3 meters) to help provide both RFIEMI and lightning 
protection. 
6.15 To ground the system (see Figure 3-34 below): 
(1) Ensure that the system’s main AC Power cable is 
not plugged into the AC outlet. (2) Mount a grounding terminal on the MDF back- 
board and connect it to: 
a. An earth ground. 
b. The ground lug on the back side of the main 
power supply chassis. 
c. Battery compartments, if used. 
d. 
Trunk gas discharge tubes, if used. 
6.16 If AC power-related problems appear on the sys- 
tem while in operation, one of the following two meth- 
ods can be used to test the ground. 
0 Use a digital multimeter to measure the difference of 
potential between the equipment cabinet ground 
point and the power neutral, and between the equip- 
ment cabinet ground point and the third wire ground. 
Ifthe voltage measurement exceeds OSV, noise may 
develop on the system. If this occurs, call an electri- 
cian. 
0 Use a Megger to test the ground point. (A Megger 
should be available through the local power compa- 
ny.) The reading should be 5 ohms or less.

Power Supply Electrical Test 
6.17 
Perform the following electrical check on the 
power supply(s). 
(1) Ensure that the main system AC power cable is 
not plugged in and that the AC POWER switch 
on the front of each power supply unit is OFF. 
(2) Check the condition of the fuses located on the 
power supply(s). 
a. On the 
main power supply unit, the main fuse 
(located on the front) should be: 3OOVAC, 
3OA, time-delay Buss SC-30 (or equivalent). 
The auxiliary fuse (located on the back) 
should be: 125/25OVAC, lOA, time-delay 
Buss SC-10 (or equivalent). The expansion 
fuse (also located on the back) should be: 
125/25OVAC, lSA, time-delay Buss SC-15 
(or equivalent). 
b. On the 
expansion power supply unit, the fuse 
on the front should be: lzS/zsOVAC, 191, 
time-delay Buss SC-15 (or equivalent). 
NOTE: Since the fuse on the main power 
supply chassis also protects the expansion 
power supply, newer-version expansion 
power supply chassis are not equipped with a 
fuse. 
(3) Plug the surge/spike Protector Provided with the 
system into a 105-125VAC, 57-63Bx, 3OA, 
single-phase commercial power source. Since 
the surge/spike protector is terminated on a 
NEMA L5-30 twist-lock plug, a compatible AC 
receptacle (L5-30R) is needed. 
NOTE: This 
MUST be an isolated, dedicated 
circuit. Do 
NOT use an extension cord when in- 
stalling the pOwer supply. Also, DO 
NOT plug 
any other equipment into the same AC outlet; 
however, the two auxiliary AC receptacles on the 
back of the main power supply can be used for 
connecting external equipment such as the pro- 
gramming monitor and/or SMDRJSMDA output 
device(s). 
(4) Plug the main system AC power cable into the 
surge/spike protector and turn ON the AC POW- 
ER switch on the 
main power supply unit first, 
then turn ON the AC POWER switch on the ex- 
pansion Power supply unit. 
CAUTION 
When powering up the entire system, turn on the 
main power supplyfirsz, then turn on the expansion 
power supply. (See page 2-10 for details.) Newer- 
version main power supply chassis have been modi- 
fied so that turning off the AC power switch will also 
turn off the expansion supply. 
(5) Measure the following system voltages. A digi- 
tal voltmeter of fo.5% accuracy is required. 
a. Referring to Figure 3-25 on page 342, Fig- 
ure 3-28 on page 3-46, and the chart follow- 
ing step b, measure the applicable voltages 
on the back of the main Telecom Mother- 
board and, if installed, the expansion Tele- 
corn Motherboard. Use ground as a 
reference. The measurements should be 
within the limits listed in the chart below. (If 
necessary, remove each power cable connec- 
tor one at a time and measure the voltage in- 
side the connector.) 
b. Referring to Figure 3-35 on page 3-57 and 
the chart below, measure the applicable volt- 
ages on the free ends of the PC Motherboard 
power cable, the two disk drive power cables, 
and the HDLC power cable. Use ground as a 
reference. The measurements should be 
within the following limits: 
-5VDC

NOTE: The CPCP measurement should be 
.7V (fo.2OV) higher than the actual +5V 
measurement. The CPCN measurement 
should be .7V (fo.2OV) lower than the ac- 
tual ground measurement. 
I 
(6) If the voltages am within the specijied limits, 
skip to step 8. 
If voltage measumnents are not within the speci- 
fied limits, remove the power cable(s) from the 
power supply(s) and check the voltages directly 
at the individual connectors on the front of the 
main and/or expansion power supply units. Refer 
to Figures 3-36 and 3-37 on pages 3-58 and 
3-59.

(7) If the voltages at the individual connectors aiz 
within the specifwd limits, replace the defective 
cable(s). 
If voltage measuremertls at the individual con- 
nectors am not within the specijied limits, re- 
place the defective power supply module(s) 
and/or the power supply chassis(s). 
(8) 
Turn OFF the AC POWER switch. 
CAUTION 
If using a hard disk drive that does not have %elf- 
parking” heads: When powering down the entire 
system, first “park the heads” on the hard disk drive 
(as outlined on page 3-154), then turn off the muin 
power supply first before turning off the expansion 
power supply. This sequence allows the hard disk 
drive to shut down properly; the reverse does not al- 
low proper shutdown and may damage the hard disk 
drive. (See page 2-10 for additional information.) 
Newer-version main power supply chassis have 
been modified so that turning off the AC power 
switch will also turn off the expansion supply.
