The
following
figure
shows
the
type
of
connector
located
on
the
power
supply
assembly.
The
connector
enables
you
to
connect
the
SAN
Volume
Controller
2145-8F2
to
the
power
source
from
the
uninterruptible
power
supply.
Fibre-channel
port
numbers
and
worldwide
port
names
Fibre-channel
ports
are
identified
by
their
physical
port
number
and
by
a
worldwide
port
name
(WWPN).
The
physical
port
numbers
identify
fibre-channel
cards
and
cable
connections
when
you
perform
service
tasks.
The
WWPNs
are
used
for
tasks
such
as
fibre-channel
switch
configuration
and
to
uniquely
identify
the
devices
on
the
SAN.
The
physical
port
numbers
are
1
-
4,
counting
from
left
to
right
when
you
view
the
rear
panel
of
the
SAN
Volume
Controller.
The
WWPNs
are
derived
from
the
worldwide
node
name
(WWNN)
of
the
SAN
Volume
Controller
in
which
the
card
is
installed.
The
WWNN
is
in
the
form
50050768010
XXXXX,
where
XXXXX
is
initially
derived
from
the
unit
and
is
specific
to
a
SAN
Volume
Controller.
You
can
change
the
XXXXX
value
by
using
the
front
panel
to
facilitate
service
controller
concurrent
replacement
and
to
enable
some
concurrent
upgrade
operations.
The
WWPNs
are
in
the
form
5005076801
QXXXXX
,
where
XXXXX
is
as
previously
stated
and
Q
is
related
to
the
port
number
as
follows:
