Installing
and
Configuring
Processor
Modules
Microcode
Component
Replacement
Each
interface
processor
contains
default
microcode
firmware
which
is
an
image
of board-specific
software
instructions
on
single
EPROM
on
each
board
Microcode
operates
with
the system
software
and
controls
features
and
functions
that
are
unique
to
an interface
processor
type
New
features
and enhancements
to
the system
or
interfaces
are often
implemented
in
microcode
upgrades
Although
each
processor
type
contains
the
latest
available
microcode
version
in
ROM
when
it
leaves
the factory
updated
microcode
images
are periodically
distributed with
system
software
images
to
enable
new
features
improve performance
or
fix
bugs
in
earlier
versions
The
latest
available
microcode
version
for
each
interface
processor
type
is
bundled
with
each
new
system
software
maintenance
upgrade
the
bundled
images
are
distributed
as
single
image on
floppy
disk
or
Flash
memory
card
Although most
upgrades
support
the
downloadable
microcode
feature
some
images
may
require
EPROM
replacement
If
necessary
use
the following
instructions
to
replace
an
interface
processor
EPROM
in
case
Flash
memory
is
damaged
or otherwise
not
available
or
to
change
the default
microcode
on
board
for
any
other
reason The
replacement
procedures
are the
same
for
each
board
with
the exception
of the
FSIP
which
uses
PLCC-type
package
for the
microcode
You must
use
PLCC
extractor
to
remove
the
FSIP microcode
component
See
Figure
5-4
You
cannot
use
small
flat-blade
screwdriver
to
pry
it
out of the socket
as
with
the older
type of
ICs
PLCC
IC
does
not
have
legs or pins
that
plug
into
the
socket
instead
the contacts
are
on
the
sides
of the
IC and
along
the inner
sides
of the socket
When
the
IC
is
seated
in
the socket
the top of the
IC
is
flush
with
the top of the socket
Forcing
small
screwdriver
or other
tool
between
the
IC and
the sides of the socket
to
pry
out the
IC
will
damage
the
component
or the socket
or
both and you
will
have
to
replace
them
