– For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls
the power to the system unit(s), or disconnect the customer’s DC power source, when directed
to disconnect power during servicing.
• Connect 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.
• An 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. (R001 part
1 of 2)
(R001 part 2 of 2):
CAUTION:
• Do 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.
• Do 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.
• Consideration 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.
•(For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets
are not attached to the rack or if the rack is not bolted to the floor. 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.
•(For xed drawers.) This drawer is a xed drawer and must not be moved for servicing unless
specied 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
part 2 of 2)
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.
• Reduce 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 conguration of the rack cabinet as you
received it. If this conguration is not known, you must observe the following precautions:
– Remove all devices in the 32U position (compliance ID RACK-001 or 22U (compliance ID
RR001) and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.

2P0-C1 is a general-purposed x8 slot and it is generally used for the Base Ethernet card. The default Base Ethernet card is EC2U.
Note the following:
• The I/O cassettes that are used in the 9043-MRX system can hold half length, full height and half length, half height PCIe adapters.
• All PCIe slots support the single root I/O virtualization (SR-IOV) function.
Firmware slot capabilities
System PCIe slots are allocated direct memory access (DMA) space using the following algorithm:
• All slots are allocated a 2 GB default DMA window.
• All I/O adapter slots (except the embedded USB) are allocated Dynamic DMA Window (DDW) capability
based on installed platform memory. DDW capability is calculated assuming 4K I/O mappings:
– For systems with less than 64 GB of memory, slots are allocated 16 GB of DDW capability.
– For systems with at least 64 GB of memory, but less than 128 GB of memory, slots are allocated 32
GB of DDW capability.
– For systems with 128 GB or more of memory, slots are allocated 64 GB of DDW capability.
– Slots can be enabled with Huge Dynamic DMA Window capability (HDDW) using the I/O Adapter
Enlarged Capacity setting in ASMI.
– HDDW enabled slots are allocated enough DDW capability to map all of installed platform memory
using 64 K I/O mappings.
– Minimum DMA window size for HDDW enabled slots is 32 GB.
– Slots that are HDDW enabled are allocated the larger of the calculated DDW capability and HDDW
capability.
Adapter placement rules
Use this information while selecting slots for installing adapters in the 9043-MRX system. Use Table 3 on
page 3 to identify adapter slot placement priorities and maximums for the system.
1. All of the x16 PCIe slots are general purpose PCIe slot.
2. Six of the x16 PCIe slots support NVlink or OpenCAPI 25 Gbs cable cards.
3. P0-C0 is for the eBMC card assembly.
4. P0-C1 is generally used for the Base Ethernet card.

Adapter placement rules and slot priorities for the EMX0 PCIe
Gen3 I/O expansion drawer
Find information about the placement rules and slot priorities for the adapters that are supported for the
EMX0 PCIe Gen3 I/O expansion drawer (EMX0 PCIe3 expansion drawer).
Slot descriptions for the EMX0 PCIe3 expansion drawer
The number of PCIe slots that are provided in the EMX0 PCIe3 expansion drawer depends on the I/O
module conguration of the EMX0 PCIe3 expansion drawer. Your conguration might have one or two
PCIe3 6-slot fanout modules installed in the rear of the EMX0 PCIe3 expansion drawer. Each PCIe3
6-slot fanout module provides six full-length, full-height, PCIe3 slots. The PCIe3 slots are compatible
with PCIe1 and PCIe2 adapters. The PCIe slots use generation 3, single-wide, blind-swap cassettes.
The I/O module in the EMX0 PCIe3 expansion drawer is connected to the system with an expansion
drawer cable pair. Each cable pair must be the same length and are attached to the T1 and T2 ports in the
I/O module and to the corresponding ports in the cable adapter in the system.
Figure 2 on page 5 shows the rear view of the EMX0 PCIe3 expansion drawer with the location codes
for the adapter slots in the PCIe3 6-slot fanout module.
Table 4 on page 6 lists the adapter slot locations and details for the EMX0 PCIe3 expansion drawer.
Note:
The left I/O module bay is congured with the rst PCIe3 6-slot fanout module slot location codes
P1-C1 through P1-C6.
The right I/O module bay is congured with the second PCIe3 6-slot fanout module slot location codes
P2-C1 through P2-C6.

1Slots P1-C1 and P2-C1 inherit the I/O Adapter Enlarged Capacity attribute from the slot in the system
that connects to the EMX0 PCIe3 expansion drawer.
Notes:
• All slots are PCIe3 slots.
• All slots support full-length, full-height adapters or short form-factor with a full-height tailstock in
single-wide, generation 3, blind-swap cassettes.
• Slots C1 and C4 in each PCIe3 6-slot fanout module are PCIe3 x16 buses and slots C2, C3, C5, and C6
are PCIe x8 buses.
• All slots support enhanced error handling (EEH).
• All PCIe slots are hot swappable and can be serviced with the power on.
• All six slots in a PCIe3 6-slot fanout module support SR-IOV shared mode.
• Only four FC EC2U adapters can be in SR-IOV mode simultaneously per 6-slot fanout module.
Firmware slot capabilities
System PCIe slots are allocated direct memory access (DMA) space using the following algorithm:
• All slots are allocated a 2 GB default DMA window.
• Slots P1-C1 and P2-C1 inherit the I/O Adapter Enlarged Capacity attribute from the slot in the system
that connects to the EMX0 PCIe3 expansion drawer.
• All other I/O adapter slots are allocated Dynamic DMA Window (DDW) capability based on installed
platform memory. DDW capability is calculated assuming 4K I/O mappings:
– For systems with less than 64 GB of memory, slots are allocated no DDW capability.
– For systems with at least 64 GB of memory, but less than 128 GB of memory, slots are allocated 16
GB of DDW capability.
