contains
information
about

components.
AC
Power
Distribution
Bus
There
are
two
types
of
ac
power
distribution
buses:
v
Type
6
power
distribution
buses
have
six
IEC320-C13,
200
V
to
240
V
ac
outlets.
An
additional
two
front
outlets
have
limited
access,
as
shown
in
the
figures
on
the
following
pages.
The
input
ac
power
to
the
bus
is
not
switched,
so
each
outlet
has
a
separate
circuit
breaker
to
protect
against
excessive
current
(see
the
schematic
on
the
following
pages).
The
type
6
power
distribution
bus
feature
codes
are
9171,
9173,
9174,
and
6xxx
v
Type
7
power
distribution
buses
have
nine
IEC320-C13,
200
V
to
240
V
ac
outlets.
The
input
ac
power
to
the
bus
is
not
switched,
so
each
group
of
three
IEC320-C13,
200
V
to
240
V
ac
outlets
has
a
separate
circuit
breaker
to
protect
against
excessive
current
(see
the
schematic
on
the
following
pages).
The
type
7
power
distribution
bus
feature
codes
are
9176,
9177,
9178,
and
7xxx.
v
9188/7188
power
distribution
buses
have
twelve
IEC320-C13,
200
V
to
240
V
ac
outlets.
The
input
ac
power
to
the
bus
is
not
switched,
so
each
group
of
two
IEC320-C13,
200
V
to
240
V
ac
outlets
has
a
separate
circuit
breaker
to
protect
against
excessive
current
(See
the
schematic
on
the
following
pages.).
A
rack
can
contain
up
to
four
vertically
mounted
ac
power
distribution
buses.
Two
additional
power
distribution
buses
(each
consuming
1
EIA
location)
can
be
mounted
horizontally
in
the
bottom
rear
of
a
Model
T00
rack,
and
three
additional
power
distribution
buses
(each
consuming
1
EIA
location)
can
be
mounted
horizontally
in
the
bottom
rear
of
a
Model
T42
rack.
The
four
vertical
mounting
slots
will
be
filled
first
before
consuming
EIA
locations
in
the
rack.
Type
6
ac
power
distribution
buses
contain
eight
200
V
to
240
V
ac
outlets
to
provide
power
to
the
devices
and
drawers.
For
type
6,
the
input
ac
power
to
the
bus
is
not
switched,
so
each
outlet
has
a
separate
circuit
breaker
to
protect
against
excessive
current.
