DANGER
viii Power Systems: Managing PCI adapters for the 8233-E8B or 8236-E8C

Observe the following precautions when working on or around your IT rack system:
vHeavy equipment–personal injury or equipment damage might result if mishandled.
vAlways lower the leveling pads on the rack cabinet.
vAlways install stabilizer brackets on the rack cabinet.
vTo avoid hazardous conditions due to uneven mechanical loading, always install the heaviest
devices in the bottom of the rack cabinet. Always install servers and optional devices starting
from the bottom of the rack cabinet.
vRack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top
of rack-mounted devices.
vEach rack cabinet might have more than one power cord. Be sure to disconnect all power cords in
the rack cabinet when directed to disconnect power during servicing.
vConnect all devices installed in a rack cabinet to power devices installed in the same rack
cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power
device installed in a different rack cabinet.
vAn electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of
the system or the devices that attach to the system. It is the responsibility of the customer to
ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
CAUTION
vDo not install a unit in a rack where the internal rack ambient temperatures will exceed the
manufacturer's recommended ambient temperature for all your rack-mounted devices.
vDo not install a unit in a rack where the air flow is compromised. Ensure that air flow is not
blocked or reduced on any side, front, or back of a unit used for air flow through the unit.
vConsideration should be given to the connection of the equipment to the supply circuit so that
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To
provide the correct power connection to a rack, refer to the rating labels located on the
equipment in the rack to determine the total power requirement of the supply circuit.
v(For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets
are not attached to the rack. Do not pull out more than one drawer at a time. The rack might
become unstable if you pull out more than one drawer at a time.
v(For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless
specified by the manufacturer. Attempting to move the drawer partially or completely out of the
rack might cause the rack to become unstable or cause the drawer to fall out of the rack.
(R001)
Safety notices ix

CAUTION:
Removing components from the upper positions in the rack cabinet improves rack stability during
relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a
room or building:
vReduce the weight of the rack cabinet by removing equipment starting at the top of the rack
cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you
received it. If this configuration is not known, you must observe the following precautions:
– Remove all devices in the 32U position and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
– Ensure that there are no empty U-levels between devices installed in the rack cabinet below the
32U level.
vIf the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from
the suite.
vInspect the route that you plan to take to eliminate potential hazards.
vVerify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the
documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.
vVerify that all door openings are at least 760 x 230 mm (30 x 80 in.).
vEnsure that all devices, shelves, drawers, doors, and cables are secure.
vEnsure that the four leveling pads are raised to their highest position.
vEnsure that there is no stabilizer bracket installed on the rack cabinet during movement.
vDo not use a ramp inclined at more than 10 degrees.
vWhen the rack cabinet is in the new location, complete the following steps:
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet.
– If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest
position to the highest position.
vIf a long-distance relocation is required, restore the rack cabinet to the configuration of the rack
cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent.
Also lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the
pallet.

The adapter information that is shown here is used during non-directed service activities. The
information can be used to:
vIdentify an adapter
vFind specific technical information about an adapter
vWhere applicable, show special installation or cabling instructions
vShow signal names for the output-pins of the adapter connectors
vWhere applicable, show the settings for switches or jumpers
Adapters can be identified by their feature code (FC) or their custom-card identification number (CCIN).
Normally, the CCIN number is labeled on the adapter.
The FRU part number (P/N) of your adapter might not match the FRU P/N listed in this information. If
the part numbers do not match, verify that the CCIN is the same. If the CCIN is same, the adapter has
the same function and can be used in the same way.
Adapters must be placed in specific peripheral component interconnect (PCI), PCI-X, or PCI Express
(PCIe) slots to function correctly or optimally. See the PCI adapter placement for system-specific
information about which slots are available and which adapters can be placed in those slots.

PCI Express
Learn about PCI Express (PCIe) adapters and slots.
PCI Express (PCIe) adapters use a different type of slot than Peripheral Component Interconnect (PCI)
and Peripheral Component Interconnect-X (PCI-X) adapters. If you attempt to force an adapter into the
wrong type of slot, you might damage the adapter or the slot. A PCI adapter can be installed in a PCI-X
slot, and a PCI-X adapter can be installed in a PCI adapter slot. A PCIe adapter cannot be installed in a
PCI or PCI-X adapter slot, and a PCI or PCI-X adapter cannot be installed in a PCIe slot. The following
illustration shows an example of a PCI-X adapter (A) next to a PCIe 4x (B) adapter.
PCIe adapters and slots come in 4 different sizes: 1x, 4x, 8x, and 16x. Smaller size adapters do fit in larger
slots, but larger size adapters do not fit in smaller slots. The following table shows PCIe slot
compatibility.

Electronic boards, adapters, media drives, and disk drives are sensitive to static electricity discharge.
These devices are wrapped in antistatic bags to prevent damage. Learn about taking precautions to
prevent damage to these devices from static electricity discharge.

vAttach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge
from damaging your hardware.
vWhen using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It
does not increase or decrease your risk of receiving electric shock when using or working on electrical
equipment.
vIf you do not have a wrist strap, before removing the product from ESD packaging and installing or
replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
vDo not remove the device from the antistatic bag until you are ready to install the device in the
system.
vWith the device still in its antistatic bag, touch it to the metal frame of the system.
vGrasp cards and boards by the edges. Avoid touching the components and gold-edge connectors on the
adapter.
vIf you need to lay the device down while it is out of the antistatic bag, lay it on the antistatic bag.
Before picking it up again, touch the antistatic bag and the metal frame of the system at the same time.
vHandle the devices carefully to prevent permanent damage.
Important partitioning considerations with dual-slot and multi-adapter
configurations
Learn about partitioning considerations with dual-slot and multi-adapter configurations.
Logical partitions can own physical I/O resources. Physical I/O resources are assigned to logical
partitions at the slot level. Assigning a slot to a logical partition enables the operating system that runs in
the logical partition to control the functionality of the I/O resource and power for that slot. When the
operating system powers a slot on or off, the physical I/O resource is powered on or off.
In some I/O configurations, the functionality of an adapter or I/O resource depends on two or more
physical slots. For example, if you have a double-wide RAID adapter (FC 2053, 2054, or 2055) that take
up two adjacent adapter slots or two separate RAID adapters paired together, both physical slots must be
assigned to the same logical partition. For example, if you install the FC 2053, 2054, or 2055 adapter in
slot 2, then the adjacent slot 3 cannot be used to install another adapter even though the slot 3 is reported
as empty. It is important to understand the wanted configuration and function being provided before
completing the logical partitioning and activation of the resources involved.
There are two I/O configurations involving adapter pairs:
vMult-initiator and high availability
vAuxiliary Write Cache
Multi-initiator and high availability
The terms multi-initiator and high availability (HA) refer to connecting multiple adapters (typically two
adapters) to a common set of disk expansion drawers for increasing availability. This configuration is also
referred to as Dual Storage IOA configuration. This type of connection is commonly done in either of the
following configurations:
Note: Some systems have SAS RAID adapters integrated onto the system boards and use a Cache RAID -
Dual IOA Enablement Card (FC 5662) to enable storage adapter Write Cache and Dual Storage IOA (HA
RAID Mode). For these configurations, installation of the Cache RAID - Dual IOA Enablement Card
places the two integrated adapters into a HA RAID configuration. There are no separate SAS cables
required to connect the two integrated SAS RAID adapters to each other.
HA two-system configuration
4Power Systems: Managing PCI adapters for the 8233-E8B or 8236-E8C

An HA two-system configuration provides a high-availability environment for system storage by enabling
two systems or partitions to have access to the same set of disks and disk arrays. This feature is typically
used with the IBMPowerHA®SystemMirror®. The IBMPowerHA SystemMirror software provides a
commercial computing environment that ensures that mission-critical applications can recover quickly
from hardware and software failures. The support for this configuration is operating system dependent.
HA single system configuration
An HA single system configuration provides for redundant adapters from a single system to the same set
of disks and disk arrays. This feature is typically referred to as Multi-Path I/O (MPIO). MPIO support is
part of the operating system support and can be used to provide a redundant IBM SAS RAID controller
configuration with RAID protected disks.
Auxiliary write cache adapter
The auxiliary write cache (AWC) adapter provides a duplicate, nonvolatile copy of write cache data of the
RAID controller to which it is connected.
Protection of data is enhanced by having two battery-backed (nonvolatile) copies of write cache, each
stored on separate adapters. If a failure occurs to the write cache portion of the RAID controller, or the
RAID controller itself fails in such a way that the write cache data is not recoverable, the AWC adapter
provides a backup copy of the write cache data to prevent data loss during the recovery of the failed
RAID controller. The cache data is recovered to the new replacement RAID controller and then written
out to disk before resuming normal operations.
The AWC adapter is not a failover device that can keep the system operational by continuing disk
operations when the attached RAID controller fails. The system cannot use the auxiliary copy of the
cache for runtime operations even if only the cache on the RAID controller fails. The AWC adapter does
not support any other device attachment and performs no other tasks than communicating with the
attached RAID controller to receive backup write cache data. The purpose of the AWC adapter is to
minimize the length of an unplanned outage, due to a failure of a RAID controller, by preventing loss of
critical data that might have otherwise required a system reload.
It is important to understand the difference between multi-initiator connections and AWC connections.
Connecting controllers in a multi-initiator environment refers to multiple RAID controllers connected to a
common set of disk enclosures and disks. The AWC controller is not connected to the disks, and it does
not perform device media accesses.
The RAID controller and the AWC adapter each require a PCI bus connection and are required to be in
the same partition. The two adapters are connected by an internal connection. For the planar RAID
enablement and planar auxiliary cache features, the dedicated connection is integrated into the system
planar.
