and
reconnection
process
described
in
the
following
steps
for
each
storage
expansion
enclosure
before
upgrading
the
next
storage
expansion
enclosure.
Disconnecting,
upgrading,
and
reconnecting
one
DS4000
EXP700
at
time
greatly
reduces
the
possibility
of
making
a
fibre
channel
cabling
error.
Note:
Before
upgrading
the
ESMs,
review
the
guidelines
in
a.
Disconnect
all
fibre
channel
cables
from
the
left
ESM
in
the
first
storage
expansion
enclosure
that
you
will
upgrade.
b.
Replace
the
left
ESM
with
the
upgrade
ESM
CRU
that
you
received
in
the
DS4000
EXP700

Follow
the
steps
for
replacing
an
ESM
in
c.
Reconnect
the
fibre
channel
cables
to
the
upgraded
ESM
in
the
first

f.
Repeat
steps
a
through

for
each
DS4000
EXP700
that
you
are
upgrading.
Complete
the
process
for
each
DS4000
EXP700
before
you
continue
with
the
next
storage
expansion
enclosure.
8.
Power
on
your
storage
subsystem.
Use
the
LEDs
to
verify
that
the
DS4000
configuration
is
operating
normally.
Correct
any
Fault
LED
errors
and
verify
that
the
ESM
port
bypass
LEDs
are
not
lit
(if
they
are,
remove
the
fibre
channel
cables
and
the
SFPs
and
reinsert
them).
Note:
Power
up
the
storage
expansion
enclosures
first
and
then
power
up
