Online-spare memory disables a failed pair of DIMMs from the system configuration and activates an online-spare pair of DIMMs to replace the failed pair. Before you can enable this feature, you must install an additional pair of DIMMs of the same speed, type, size (or larger), and technology as the failed pair of DIMMs. For more information see "Installing a memory module" on page 54 v PCI Express adapter capabilities The server has three slots for low-profile PCI Express adapters (two x8 and one x4). The x8 slots accept a x4 adapter. The server also has one full-height, full-length slot on the riser-card assembly for an optional PCI Express x16 adapter or an optional PCI-X 133 MHz adapter. v HTX adapter capabilities The server supports an HTX adapter slot on the riser-card assembly. You can replace the HTX adapter slot with an optional PCI-X 133 MHz riser-card adapter or PCI Express x16 riser-card assembly. v Power Executive Power Executive is an IBM Director extension that measures and reports server power consumption as it occurs. This enables you to monitor power consumption in correlation to specific software application programs and hardware configurations. You can obtain the measurement values through the systems-management interface, and can view them using IBM Director. For more information, including the required level of IBM Director and PowerExecutive, see the IBM Director documentation on the IBM Director CD, or see www.ibm.com/servers/eserver/xseries/systems_management/ibm_director/ extensions. v Redundant connection The addition of an optional network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the redundant NIC. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention. v Redundant cooling and power capabilities The server supports up to 10 hot-swap fans, in multiples of 5, which provide redundant cooling. Redundant cooling enables continued operation if one of the fans fails. The server supports up to two 835-watt power supplies, which provide redundancy and hot-swap capability for a typical configuration. When the maximum load on the server is less than 835 watts and a problem occurs with one of the power supplies, the other power supply can meet the power requirements. v ServeRAID support The server supports an internal ServeRAID-8k or 8k-l SAS Controller, which is required for you to use the hot-swap hard disk drives and to create redundant array of independent disks (RAID) configurations. v Systems-management capabilities The server supports an optional Remote Supervisor Adapter II SlimLine which provides service-processor functions in addition to those that the BMC provides. When this adapter is used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The Remote Supervisor Adapter II SlimLine also provides system monitoring, event recording, and dial-out alert capability. Chapter 1. The System x3655 Type 7985 server 7

Online-spare
memory
disables
a
failed
pair
of
DIMMs
from
the
system
configuration
and
activates
an
online-spare
pair
of
DIMMs
to
replace
the
failed
pair.
Before
you
can
enable
this
feature,
you
must
install
an
additional
pair
of
DIMMs
of
the
same
speed,
type,
size
(or
larger),
and
technology
as
the
failed
pair
of
DIMMs.

v
PCI
Express
adapter
capabilities
The
server
has
three
slots
for
low-profile
PCI
Express
adapters
(two
x8
and
one
x4).
The
x8
slots
accept
a
x4
adapter.
The
server
also
has
one
full-height,
full-length
slot
on
the
riser-card
assembly
for
an
optional
PCI
Express
x16
adapter
or
an
optional

133
MHz
adapter.
v
HTX
adapter
capabilities
The
server
supports
an
HTX
adapter
slot
on
the
riser-card
assembly.
You
can
replace
the
HTX
adapter
slot
with
an
optional
PCI-X

riser-card
adapter
or
PCI
Express
x16
riser-card
assembly.
v
Power
Executive
Power
Executive
is
an
IBM
Director
extension
that
measures
and
reports
server
power
consumption
as
it
occurs.
This
enables
you
to
monitor
power
consumption
in
correlation
to
specific
software
application
programs
and
hardware
configurations.
You
can
obtain
the
measurement
values
through
the
systems-management
interface,
and
can
view
them
using
IBM
Director.
For
more
information,
including
the
required
level
of
IBM
Director
and
PowerExecutive,
see
the
IBM
Director
documentation
on
the
IBM
Director
CD,
or
see
www.ibm.com/servers/eserver/xseries/systems_management/ibm_director/
extensions.
v
Redundant
connection
The
addition
of
an
optional
network
interface
card
(NIC)
provides
a
failover
capability
to
a
redundant
Ethernet
connection.
If
a
problem
occurs
with
the
primary
Ethernet
connection,
all
Ethernet
traffic
that
is
associated
with
the
primary
connection
is
automatically
switched
to
the
redundant
NIC.
If
the
applicable
device
drivers
are
installed,
this
switching
occurs
without
data
loss
and
without
user
intervention.
v
Redundant
cooling
and
power
capabilities
The
server
supports
up
to
10
hot-swap
fans,
in
multiples
of
5,
which
provide
redundant
cooling.
Redundant
cooling
enables
continued
operation
if
one
of
the
fans
fails.
The
server
supports
up
to
two
835-watt
power
supplies,
which
provide
redundancy
and
hot-swap
capability
for
a
typical
configuration.
When
the
maximum
load
on
the
server
is
less
than
835
watts
and
a
problem
occurs
with
one
of
the
power
supplies,
the
other
power
supply
can
meet
the
power
requirements.
v
ServeRAID
support
The
server
supports
an
internal
ServeRAID-8k
or
8k-l
SAS
Controller,
which
is
required
for
you
to
use
the
hot-swap
hard
disk
drives
and
to
create
redundant
array
of
independent
disks
(RAID)
configurations.
v
Systems-management
capabilities
The
server
supports
an
optional
Remote
Supervisor
Adapter
II
SlimLine
which
provides
service-processor
functions
in
addition
to
those
that
the
BMC
provides.
When
this
adapter
is
used
with
the
systems-management
software
that
comes
with
the
server,
you
can
manage
the
functions
of
the
server
locally
and
remotely.
The
Remote
Supervisor
Adapter
II
SlimLine
also
provides
system
monitoring,
event
recording,
and
dial-out
alert
capability.
