Installation
guidelines
The
BladeCenter
QS21
is
a
hot-swappable
device:
you
can
install
or
remove
the
blade
server
while
the
BladeCenter
unit
is
running.
Additionally,
the
BladeCenter
QS21
can
operate
alongside
different
blade
servers
in
the
same
BladeCenter
unit.
Attention:
If
you
plan
to
remove
a
blade
server
and
reinstall
it,
be
sure
to
note
the
number
of
the
bay
that
contains
the
blade
server
before
you
remove
it.
You
must
reinstall
the
blade
server
in
the
same
bay
from
which
it
was
removed.
Reinstalling
a
blade
server
into
a
different
bay
than
the
one
from
which
it
was
removed
could
have
unexpected
consequences,
such
as
incorrect
reconfiguration
of
the
blade
server.
Some
blade
server
configuration
information
and
update
options
are
established
according
to
bay
number.
If
you
reinstall
the
blade
server
into
a
different
bay,
you
might
have
to
reconfigure
the
blade
server.
Statement
21:
CAUTION:
Hazardous
energy
is
present
when
the
blade
server
is
connected
to
the
power
source.
Always
replace
the
blade
cover
before
installing
the
blade
server.
For
information
about
the
design
of
the
BladeCenter
unit,
including
the
hot-swap
blade
bays,
see
the
documentation
that
comes
with
the
BladeCenter
unit.
While
you
can
install
or
remove
the
blade
server
without
removing
power
from
the
BladeCenter
unit,
you
must
turn
off
the
blade
server
before
removing
it
from
the
BladeCenter
unit.
The
maximum
number
of
blade
servers
that
the
BladeCenter
unit
supports
varies
by
the
wattage
of
the
power
supplies
that
are
installed
in
the
BladeCenter
unit.
For
more
information
about
determining
the
power
requirements
for
the
blade
server,

IBM
BladeCenter
Power
Module
Upgrade
Guidelines
