tolerance allow a wide choice of locations for the equipment
cabinet, the SUPERSET
Maintenance
2.04 The modular design and functional packaging of the SX-
lOO/SX-200 system permits rapid location and replacement of
defective equipment. Circuit malfunctions are detected by diagnostic
routines automatically initiated by the CPU. These diagnostic routines,
which are detailed in Section MITL9105/91 lo-096-500-NA and Section
(MAP ), locate the defective circuit card or assembly and indicate to
S
the service personnel the required field-replaceable unit. Diagnostic
routines and maintenance procedures do not interfere with users not
affected by the malfunction. Because the system employs only elec-
tronic circuits, preventative maintenance is not required.
2.05 System expansion is achieved by the addition of plug-in line
and trunk printed circuit cards. Standard lines and the SUPER-
SET lines are added in increments of eight, CO trunks are added in the
increments of four and tie trunks are added in increments of two. All
connections from the cross-connecting terminals to the equipment
cabinet are made using connectorized cables. Connections between
the cross-connecting terminals and external equipment are made in
accordance with accepted practice.
Physical Description
2.06 The SX-100 equipment cabinet (see Figure 2-2) is of metal
construction and has the following dimensions: height, 422 mm
(16.62 in.); width, 635 mm (25 in.); and depth, 470 mm (18.5 in.). The
weight of a fully equipped system is approximately 31.8 kg (70 lb). For
a full description, see Section MITL9105/91 lo-096-150-NA.
2.07 The SX-200 equipment cabinet (see Figure 2-3) is of metal
construction and has the following dimensions: height, 960 mm
(38 in.); width, 600 mm (23.5 in.); and depth, 700 mm (27.5 in.). The
weight of a fully equipped system is approximately 131.7 kg (290 lb).
For a full description, see Section MITL9105/91 lo-096-150-NA.
Equipment Cabinet
2.08 The door on the front of the cabinet provides access to the
system maintenance panel and the printed circuit cards. In the
SX-100 system, a removable rear panel provides access to the system
power supply and to the line and trunk connections. In the SX-200
system, a hinged lockable rear panel provides access to the system
power supply and to the line and trunk connections. Cable entry to the
equipment cabinet is provided through a cable duct in the rear of the
cabinet. The equipment cabinet holds the maintenance panel, an
equipment shelf, printed circuit cards and the primary power supply. In
addition, a reserve power supply may be mounted in the bottom of the
SX-200 system or form a pedestal for the SX-100 PABX.
