Removing
 
and
 
installing
 
blower
 
modules
 
The
 
BladeCenter
 
T
 
unit
 
comes
 
with
 
four
 
hot-swap
 
blowers
 
for
 
cooling
 
redundancy.
 
The
 
blowers
 
are
 
installed
 
at
 
the
 
rear
 
of
 
the
 
system.
 
The
 
blower
 
speeds
 
vary
 
depending
 
on
 
the
 
ambient
 
air
 
temperature
 
at
 
the
 
front
 
of
 
the
 
BladeCenter
 
T
 
unit.
 
If
 
a
 
blower
 
fails,
 
the
 
remaining
 
blowers
 
increase
 
their
 
speed
 
to
 
cool
 
the
 
BladeCenter
 
T
 
unit
 
and
 
blade
 
servers.
 
All
 
flour
 
blowers
 
are
 
required
 
for
 
redundant
 
system
 
operation.
 
Power
 
for
 
all
 
four
 
blowers
 
is
 
shared
 
by
 
all
 
installed
 
power
 
modules.
 
One
 
failed
 
blower
 
creates
 
a
 
nonredundant
 
configuration.
 
Note:
  
Each
 
power
 
module
 
has
 
cooling
 
fans
 
that
 
are
 
independent
 
from
 
the
 
system
 
cooling.

cooling
 
redundancy.
