HSL
Loop
cable,
the
HSL
loop
connections
(external
or
embedded)
or
an
HSL
interposer
card
in
an
HSL
loop.
The
failing
component
is
an
HSL
cable,
the
HSL
connections
(external,
internal,
or
embedded),
an
internal
HSL
ribbon
cable,
an
HSL
link
embedded
in
a
FRU,
or
an
HSL
interposer
card
in
an
HSL
loop.
Warning:
If
an
HSL
cable
is
pulled,
it
may
result
in
the
HSL
connection
being
lost
to
frames
that
were
in
a
loop
after
the
cable
is
reconnected.
To
fix
this,
you
will
need
to
cycle
power
on
the
frame
with
the
locked
HSL
connection.
If
this
occurs,
follow
the
Power
down,
power
on
instructions
(See
page
instructions
below
to
power
down
the
frames,
reconnect
the
HSL
cable,
and
power
the
frames
back
on.
The
name
of
the
symbolic
FRU
given
in
the
Service
Action
Log
(SAL)
gives
information
about
the
type
of
connection
at
the
failing
port.
Use
information
about
the
connection
on
each
end
of
the
cable
to
determine
the
cable
type.
v
BUSCBL1
indicates
the
connection
is
an
optical
connection.
