#6 AWG insulated green wire connected directly to both points
only.
The system cabinets and associated 
ducting hardware shall not
be exposed to any ground source other than that described in
subparagraph (a) above.
AC service wires bringing AC to the cabinets shall not share anenclosure or raceway with other system grounds, DC power
distribution wires, or signaling wires.
All system hardware shall be provided with connections to the
system single point ground which in turn shall be provided witha reliable path to the equipment grounding conductor (i.e.,
green wire ground or safety ground), which shall be connected
to an approval building ground (cold water pipe).
All sources of external ground (e.g., system signaling ground to
the approved ground source) shall connect only to the system
single point ground.A separate grounding conductor (minimum size 14 AWG) shall
be run from the system single point ground to the communica-
tions ground system on the cross-connect field.
All doors, shelves, and similar assemblies are to be connected
by straps to their designated connection points on the cabinet.

4. CONTROL SHELF AND PERIPHERAL SHELF BACKPLANES AND WIRING
Control Shelf (with COMBO backplane - 336, 456, and 480 ports)
4.01The Control Shelf combination backplane is an integral part of
the Control Shelf and serves Bay 1 and Bay 2 to connect the
various circuit cards.
4.02The 12 Peripheral cards are arranged in two rows; the upper
row designated by square and circular identifications, and the
lower row by circular identifications. Four of the Peripheral cards areon Bay 2 (two rows of two cards) and Bay 1 contains eight Peripheral
cards (two rows of four). Cards with a square on their faceplate may
only be installed in upper card slots; cards with a circle on their
faceplate may be installed in either upper or lower card slots. Similarly,the MCC has a star, the Bay Control Card has a semi-circle, the Bay
Power Supply has a right triangle, and the Disk Drive has an equilateral
triangle to identify their respective card slots.
4.03SX-200 Welded Control Cabinet 
- Figure 4-1 shows the ap-
proximate locations of the backplane connectors as viewed
from the rear of a Control cabinet. Note that the floppy disk drive
connects to the backplane with a ribbon cable and a power cable.
Figure 4-2 shows Control cabinet grounding connections; Figure 4-3
shows Control cabinet power distribution; Figure 4-4 shows signal
cable routing.
4.04SX-200 Universal Control Cabinet 
- Figure 4-5 shows the ap-
proximate locations of the backplane connectors as viewed
from the rear of an SX-200 Control cabinet. Note that the floppy disk
drive plugs directly into this backplane. Figure 4-6 shows Control
cabinet grounding connections;Figure 4-7 shows Control cabinet
power distribution; Figure 4-8 shows signal cable routing.672-Port Control Cabinet and Control Backplane
4.05 672-Port Control Cabinet 
-Figure 2-5 shows a 672-Port Con-
trol Cabinet; Figure 4-15 shows the power and ground wiring
for the 672-Port Control Cabinet, and Figure 4-16 shows the signal
wiring. The Control bay (Bay 0) contains a Main Control Card, a SwitchMatrix Card, a Bay Power Supply, and two Floppy Disk Drives; it does
not contain any peripheral cards.4.06 672 Port Control Backplane 
-Figure 4-14 shows the approxi-
mate locations of the backplane connectors as viewed from the
rear of a Control Cabinet.Peripheral Shelf 
- 480-Port Configuration
4.07Up to three analog Peripheral shelves may be supplied with an
SX-200 DIGITAL PABX. The peripheral shelf in the Control cabi-
net is Bay 3; the lower peripheral shelf in the peripheral cabinet is Bay4; the upper shelf in the peripheral cabinet is Bay 5. Bays 3 and 4 are

identical, while Bay 5 has fewer printed circuit boards. In an SX-lClO@
PABX upgrade, the SX-700 cabinet contains only Bay 4.

4.08An Analog Peripheral Shelf may have a Surge Clamp on its
backplane at Slot 16, Pin 10 as shown in Figure 4-l 1; these
surge clamps are optional.Peripheral Shelf 
- 336-Port Configuration
4.09The Universal Cabinet can be expanded by adding a Digital
Peripheral shelf above the Control shelf; it contains Digital Bay
3 and (optionally) Digital Bay 4; each Bay contains 96 ports. These baysare the same as Bay 1, except each contains a Bay Control Card
instead of a Floppy Disk Drive. Figure 4-12 shows AC and ground
distribution, while Figure 4-13 shows signal cable distribution within
the Universal cabinet.Peripheral Shelf 456-Port Configuration
4.10 The Universal Cabinet can be expanded by adding a Digital
Peripheral shelf above the Control shelf; it contains Digital Bay3 only (96 ports). An analog Peripheral cabinet (Bays 4 and 5) may be
connected instead of Digital Bay 4, to provide up to 456 ports.672-Port Peripheral Cabinet and Shelves
4.11The 672-Port Peripheral Cabinet contains up to two shelves and
four Peripheral Bays. Each Bay contains a Bay Power Supply, a
Bay Control Card, and up to eight peripheral cards. The digital bays arethe same as used in the 336-port and 456-port systems, and for the
three Peripheral bays in the Control cabinet. The 
672-Port Peripheral
Cabinet is shown in Figure 2-6; Figure 4-16 shows the signal wiring.
The 672-Port Peripheral Cabinet power and ground wiring is shown in
Figure 4-17; Figure 4-18 shows its signal wiring.
