Cabling
and
Connectivity
Cable
Installation
Planning
Before
you
place
your
cable
order,
consider
your
future
growth
needs.
You
may
wish
to
order
cables
longer
than
you
need
right
now
to
avoid
expansion
problems
in
the
future.
As
processor
packaging
evolves,
internal
locations
for
various
cable
connections
may
shift,
necessitating
longer
cables,
even
though
the
floor
locations
of
connected
devices
have
not
changed.
The
zSeries
800
family
recognizes
industry
trends
toward
the
use
of
standardized
channel
cable
connectors.
The
same
types
of
fiber
optic
connectors
used
in
local
area
and
storage
area
networks
are
also
used
to
connect
channel
features
in
the
zSeries
800.
Following
are:

Cabling
Service
and
a
list
of
customer
responsibilities
if
you
elect
not
to
use
the
service

v
An
illustration
showing
how
to
correctly
route
fiber
optic
cables
to
provide
proper
cable
strain
relief
and
ensure
design
performance.
v
Descriptions
of
the
channel
features
for
the
zSeries
800
system,
including
the
Fiber
Quick
Connect
trunking
system
for
ESCON
cables.
Note:
The
Fiber
Quick
Connect
trunking
system
cannot
be
used
in
a
non-raised
floor
installation.
There
is
not
enough
space
to
obtain
correct
cable
bend
radius
at
the
tailgate
exit
area.
zSeries
Fiber
Cabling
Service
The
connectivity
environment
has
become
much
more
complex,
and
proper
planning
and
installation
of
fiber
cabling
is
critical
to
maximize
the
benefits
of
high
speed
protocols
such
as
FICON,
Fibre
Channel
Protocol,
Coupling
Facility
links
and
Gigabit
Ethernet.
These
protocols
require
planning
for
different
fiber
types,
new
fiber
optic
connectors,
and
current
and
future
data
rates
to
determine
optimal
connectivity
and
cabling
options.
