Installation
considerations
This
chapter
describes
the
installation
site
physical
requirements
that
must
be
in
place
to
be
able
to
complete
the
installation
of
a
BladeCenter
unit.
The
following
topics
are
discussed:
v
“Physical
planning”
describes
chassis
dimensions,
weight,
floor
space,
and
noise
considerations.
v
“Rack
considerations”
on
page
43
describes
weight
and
space
limits
of
IBM
NetBAY
racks.
v
“Power
considerations”
on
page
45
describes
rack
and
BladeCenter
unit
power
requirements
v
“Cooling
considerations”
on
page
50
describes
temperature
and
humidity,
air
flow,
room
cooling,
and
heat
output.
v
“Power
connections”
on
page
51
provides
sample
diagrams
for
power
and
cabling.
v
“Physical
installation
time”
on
page
72
shows
approximate
times
for
installing
BladeCenter
units,
blade
servers,
and
other
components.

Physical
planning
This
section
describes
dimensions,
weight,
floor
space,
and
noise
considerations.
Dimensions
A
BladeCenter
unit
has
the
following
dimensions:
Width
444
mm
(17.5
in.)
Height
304.2
mm
(12
in.)
Depth
711.2
mm
(28
in.)
A
BladeCenter
unit
uses
7U
of
vertical
rack
space.
The
following
clearances
are
required
inside
the
rack:
50
mm
(1.96
in.)
on
each
side
of
the
chassis
100
mm
(3.93
in.)
at
the
back
of
the
chassis
for
cables.
Weight
considerations
The
following
factors
are
important
when
planning
for
the
physical
installation
of
BladeCenter
units:
v
Racks
have
a
maximum
weight
load
limit.
v
Floors,
particularly
raised
floors
have
maximum
weight
limits.
Floor
space
Figure
9
on
page
42
shows
the
required
floor
space
for
an
IBM
NetBAY
rack.
This
diagram
shows
the
space
needed
to
allow
enough
clearance
in
the
front
and
rear
of
the
rack
to
be
able
to
open
the
doors
to
access
the
equipment.
Front
clearance
is
needed
to
have
access
to
the
blade
servers
and
the
BladeCenter
media
tray.
Rear
clearance
is
needed
to
access
power
supplies,
blowers,
network
cable
connections,
