cable
for
the
Ethernet
management
port.
Replacing
a
defective
cable
in
a
harness
If
a
cable
in
a
harness
is
defective,
complete
the
following
steps
to
replace
the
cable:
1.
Make
sure
that
the
power
for
the
device
with
the
defective
cable
is
turned
off.
2.
Disconnect
both
ends
of
the
defective
cable
from
their
ports.
Do
not
remove
any
other
connectors
from
their
ports.
3.
If
possible,
remove
the
cable
from
the
harness.
Otherwise,
use
a
pair
of
wire
cutters
to
cut
off
the
connectors
at
both
ends
of
the
defective
cable.
This
prevents
someone
from
mistakenly
reconnecting
the
cable,
thinking
that
it
has
inadvertently
been
left
unconnected.
4.
Using
a
wire
nut
or
electrical
tape,
secure
the
exposed
cable
wires.
5.
Install
a
single
cable
between
the
two
empty
ports.
Use
wire
ties
to
attach
the
cable
to
the
harness
that
contains
the
defective
cable.
This
identifies
the
replacement
cable
as
belonging
to
this
harness.
6.
Label
the
replacement
cable
so
it
is
clearly
identified
as
a
replacement.
