you
must
follow
when
installing

LAN
and
switch
cables.
Failure
to
follow
these
procedures
may
damage

The
objectives
of
these
procedures
are
to:
v
Provide
switch
cables
with
continuous
support
and
strain
relief
v
Minimize
the
possibility
of
pin

to
the
SNI

v
Form
consistent

Cable
Installation
and
Management
Procedure
Concepts
In
some
configurations,
cables
that
are
not
properly
supported
have
damaged
the
associated
connectors.
However,
connector
damage
can
be
prevented
by
following
the
procedure
described
in
this
section.
This
procedure
must
be
used
for
installing
I/O
cables,
administrative
LAN
cables,
and
switch
cables
in
a
M/T
7040-W42
frame.
This
procedure
is
written
for
a
frame
that
is
fully
populated
with
pSeries
655
nodes.
If
the
frame
you
are
installing
is
not
fully
populated,
adjust
this
procedure
as
needed.
A
high-level
workflow
for
cable
installation
is
as
follows:
1.
Install
frame
2.
Route
all
signal
cables
up
through
the
tailgate
3.
Separate
cables
into
groups
for
nodes
on
the
left
side
of
the
frame
and
for
nodes
on
the
right
side
of
the
frame
Note:
Switch
cables
must
not
be
connected
to
SNIs
or
switch
port
connection
cards
until
the
weight
of
each
cable
is
fully
supported.
4.
Make
certain
that
switch
cable
groupings
do
not
interfere
with
PCI
adapter
slots
5.
Make
certain
that
the
cable
bend
radius
allows
clearance
for
closing
the
rear
door
but
is
not
so
sharp
that
it
places
excessive
strain
on
the
cable
or
the
associated
connectors
6.
Cable
the
frame
starting
with
the
upper
nodes
and
working
down
7.
Apply
tailgate
support
for
the
cables
from
left
to
right
