Model
D10
Overview
The
Model
D10
is
a
19-inch,
rack-mountable
I/O
subsystem
that
is
attached
to
a
processor
subsystem
drawer
to
extend
the
system’s
capacity
for
I/O
adapters.
The
I/O
drawer
includes
redundant
concurrently
maintainable
power
and
cooling.
Five
PCI-X
slots
and
one
PCI
slot
are
available
for
PCI
adapters.
PCI
adapters
are
installed
through
the
rear
of
the
I/O
subsystem
using
PCI
adapter
cassettes.
Because
the
PCI
slots
support
hot-pluggable
adapters,
the
I/O
subsystem
can
have
adapters
installed
without
turning
off
power
or
removing
covers.
The
Model
D10
is
4
EIA
units
high.
Two
Model
D10s
can
be
installed
side-by-side
in
a
19-inch
rack
enclosure.
