Electrical Safety
Observe the following safety instructions any time you are connecting or disconnecting devices attached to
the workstation.
In the system you are about to setup or service:
v The ac power interface connector is considered the main power disconnect device.
v This system has redundant power supply capabilities, meaning that it has the ability to have two power
supplies running simultaneously in the same system unit. When instructed to disconnect the power
source, ensure that all power cables have been unplugged.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on 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.
Before installing or removing signal cables, ensure that the power cables for the system unit
and all attached devices are unplugged.
When adding or removing any additional devices to or from the system, ensure that the power
cables for those devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers, telephones, or
station protectors for communications lines.

Laser Safety Information
CAUTION:
This product may contain a CD-ROM, DVD-ROM, or laser module on a PCI card, which are class 1
laser products.
C30
Laser Compliance
All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for class
1 laser products. Outside the U.S., they are certified to be in compliance with the IEC 825 (first edition
1984) as a class 1 laser product. Consult the label on each part for laser certification numbers and
approval information.
CAUTION:
All IBM laser modules are designed so that there is never any human access to laser radiation
above a class 1 level during normal operation, user maintenance, or prescribed service conditions.
Data processing environments can contain equipment transmitting on system links with laser
modules that operate at greater than class 1 power levels. For this reason, never look into the end
of an optical fiber cable or open receptacle. Only trained service personnel should perform the
inspection or repair of optical fiber cable assemblies and receptacles.

Data Integrity and Verification
IBM computer systems contain mechanisms designed to reduce the possibility of undetected data corruption
or loss. This risk, however, cannot be eliminated. Users who experience unplanned outages, system failures,
power fluctuations or outages, or component failures must verify the accuracy of operations performed and
data saved or transmitted by the system at or near the time of the outage or failure. In addition, users must
establish procedures to ensure that there is independent data verification before relying on such data in
sensitive or critical operations. Users should periodically check the IBM support websites for updated
information and fixes applicable to the system and related software.

Chapter 1. Reference Information
This chapter provides reference information for the Model D10 and Model D20 I/O subsystems.
pSeries 7311 Model D10 Overview
The Model D10 is a 19-inch, rack-mountable I/O subsystem that is attached to a processor subsystem
drawer to extend the system’s capacity for I/O adapters. The I/O drawer includes redundant concurrently
maintainable power and cooling.
Five PCI-X slots and one PCI slot are available for PCI adapters. PCI adapters are installed through the
rear of the I/O subsystem using PCI adapter cassettes. Because the PCI slots support hot-pluggable
adapters, the I/O subsystem can have adapters installed without turning off power or removing covers. The
Model D10 is 4 EIA units high. Two Model D10s can be installed side-by-side in a 19-inch rack enclosure.

FRUs:
v LED indicators visible on each PCI adapter cassette
v LED indicators on the I/O subsystem backplane
v Attention/Identify LEDs for power supplies and fans
For more information on LEDs and their definitions, see Chapter 5, “Fault and Attention LEDs,” on page
173.
D10 PCI-X Slots
The Model D10 has five PCI-X slots and one PCI slot. Adapters are installed and removed using a PCI
adapter cassette, which allows adapters to be installed without turning off the power or opening the I/O
subsystem covers.
PCI adapters are installed using an adapter cassette, each adapter cassette shows two LEDs for each
adapter. There is a green power indicator LED (upper) and an amber fault/identify LED (lower). The slots
are numbered on the rear of the chassis from left to right 1 through 6. Slot 1 is a 5V PCI slot. Slots 2
through 6 are 3.3V PCI-X.
I/O Subsystem PCI-X Slot LED Definitions
The green and amber LEDs (viewed on the rear of the PCI adapter cassette when installed) are used to
indicate the state of the PCI slot during removal and replacement of an adapter. The following table
describes the LED states and their definitions.

D10 Power
The following figure shows the front view of the pocessor subsystem and two I/O subsystems. Each unit
has two power supplies and two power cords for redundancy. Connect the power cords from one side of
the system to one power distribution bus in the rack. Connect the power cords from the other side of the
system to a different power distribution bus in the rack. To ensure that the systems in a rack keep running
if power is interrupted, a separate branch power line for each side of the rack must be used.

The Model D10 I/O subsystem has two power supplies. Either power supply is capable of providing the
necessary voltages and currents, independent of the other power supply. Each power supply provides 5V
dc, 3.3V dc, -12V dc, and 5V dc standby. The power supplies are hot-pluggable and may be changed one
at a time while the system is operational.

D10 Cooling
Fans mounted inside each I/O subsystem power supply and an additional fan mounted on the front of the
subsystem provide cooling. The power supplies and the fan can be removed and replaced with the power
turned on, as long as only one fan is removed from the I/O subsystem at a time.
D10 Input/Output Ports
The connector ports on the rear of the Model D10 I/O subsystem are used to connect the RIO-2 cables,
the SPCN cables, and the rack-beacon LED.
Chapter 1. Reference Information 5
Subsystem Positioning and Cabling
I/O subsystems can be installed in a standard 19-inch EIA rack in any location. The cables that connect
the subsystems allow some flexibility in drawer placement, but the I/O subsystems should be located
above the processor subsystem to which they are connected in the same rack.
Up to eight I/O subsystems can be connected to a processor subsystem. Use the following guidelines:
v Each I/O subsystem connects to the processor subsystem using one system power control network
(SPCN) cable loop.
v Each I/O subsystem connects to the processor subsystem using one or more remote I/O (RIO) cable
loops.
v Lowest cost configurations allow up to four I/O subsystems connected to the processor subsystem using
a single RIO loop.
v Optimum performance is achieved when each I/O drawer is connected to the processor subsystem
through its own RIO loop.
Note:
The cabling illustrations in this section show examples of how the cabling between a processor
subsystem and connected I/O subsystems can be done. The example illustrations show the logical
connections of SPCN and RIO cables. Your system’s cables might be physically connected in a
different way from these examples.
SPCN Cabling
I/O subsystem SPCN cables are connected to the processor subsystem unit in a loop configuration. The
SPCN cables are connected in a loop so that the system has two paths to each I/O subsystem. Up to
eight I/O subsystems are supported on one SPCN loop.
One I/O Subsystem, Two I/O Subsystems: The illustrations on the left show one I/O subsystem
connected to the processor subsystem. The illustrations on the right show two I/O subsystems connected
to the processor subsystem using one SPCN loop.

subsystems connected to the processor subsystem using one SPCN loop.

1 Processor Subsystem
2 I/O Subsystem
RIO Cabling
I/O subsystems are connected to the processor subsystem through remote I/O (RIO) cable loops. The
cable loops are connected to ports that are on the rear of the processor subsystem. The RIO cables are
connected in loops so that the system has two paths to each I/O subsystem when more than one I/O
drawer is in a loop.
If only one I/O subsystem is in a RIO loop and both the processor subsystem and the I/O subsystem are
RIO-2 capable, the RIO-2 cables are used as one two-cable path to the I/O subsystem. In this cable
configuration, the data rate is increased by a factor of 2.
v A maximum of eight Model D10 drawers are supported on one processor subsystem.
v If both D10 I/O drawers are connected to the same processor subsystem, the total number of I/O
subsystems supported is eight.
v The maximum number of I/O subsystems supported on one RIO loop is four.
v The D10 I/O drawers must be on separate RIO loops.
v The speed at which a RIO loop operates is set by the capability of the drawers on the loop. If the
system is capable of operating at RIO-2 speed, but any drawer on the same loop is capable of RIO
speed, the whole loop operates at RIO speed.
The system can have up to four RIO loops. A total of eight I/O drawers can be connected to the processor
subsystem in a variety of cabling configurations. For optimum performance, connect the RIO loops in a
configuration that distributes multiple I/O drawers among as many RIO loops as possible. A dedicated RIO
loop for each I/O drawer can provide optimum performance. Some examples of valid cabling examples
follow.

Model D10 Location Codes
This system (processor subsystem and attached I/O subsystems) use physical location codes in
conjunction with AIX location codes to provide mapping of failing field replaceable units (FRUs). The
location codes are produced by the processor subsystem’s firmware and AIX. For information about how to
read a location code, see the service guide for the processor subsystem to which your I/O subsystem is
connected.
AIX and Physical Location Code Table
This section covers the AIX and Physical Location Code tables for the Model D10.
The tables in this section contain the location codes for I/O subsystems when they are attached to the
system unit. In the tables, the location code for the I/O subsystem number is represented by dd. The first
time that an installed system is powered on, the I/O subsystems are numbered. For example, if a system
is first powered on with eight I/O subsystems connected, the dd value for the subsystems should be
numbered from 2 through 9.
Note: If the system was powered on with I/O subsystems connected before delivery to the customer, the
I/O subsystem location codes for the connected I/O subsystems are permanently set.
If at a later time, an I/O subsystem is removed from the system and a different I/O subsystem is
substituted, the substitute is assigned the next higher number available for its value of dd, which in the
earlier example, is 10. If the original I/O subsystem is reinstalled in the system configuration, the system
uses the original dd value for the I/O subsystem.
To keep the system from renumbering the I/O drawer when an I/O backplane is replaced, the VPD module
from the old I/O backplane must be moved over to the new I/O backplane.
The following diagram defines each part of a location code.
Ux.dd-xx-yy
| | | |
| | | |
| | | yy This code is used for the next component (yy, yy, yy, ...)
| | xx This code is used for the next component (Px, Fx, Vx, ...)
| dd This code is the location code for the I/O drawer (2 to 63)
Ux This code normally identifies the rack in which a drawer is installed.
The x will always be zero (0) for this system.
