How This Book Is Organized
The chapters in this manual contain a series of related service tasks. Using the table
of contents or the task list on the first page of each chapter, you can quickly find the
procedure you need to perform a specific task. The procedures for the tasks are brief;
however, they are interrelated and often refer to other modules in the book. For
instance, the procedure “How to Remove the Motherboard” is related to many tasks
covered by other modules. You must perform these requisite tasks before or after
replacing the motherboard.
This book is divided into seven chapters and six appendixes.
■ Chapter 1 describes the tasks that you need to perform before or after each service
procedure.
■ Chapter 2 explains tasks related to components on the motherboard side of the
system.
■ Chapter 3 describes tasks related to components on the input/output (I/O) board
side of the system.
■ Chapter 4 explains tasks related to storage devices.
■ Chapter 5 provides information about tasks related to various subassemblies in
the system.
■ Chapter 6 describes tasks related to system backplanes and cables.
■ Chapter 7 provides configuration information for various parts of the system.
■ The appendixes provide information about field-replaceable units (FRUs), system
LEDs, split backplane configurations, connector pinouts, system specifications,
and safety precautions.

About Hot-Pluggable and Hot-Swappable Components
Sun Fire V890 systems feature a variety of components that can be serviced while the
machine is running.
Hot-pluggable components are components that a qualified service technician can
install or remove while the system is running, without affecting the rest of the
system’s capabilities. However, in many cases, you must prepare the operating
system prior to the hot-plug event by performing certain system administration
tasks.
6 Sun Fire V890 Server Service Manual • October 2005
Components that can be serviced without such preparation are called hot-swappable
components. These components can be removed or inserted at any time without
preparing the operating system in advance.
Sun Fire V890 hot-pluggable components fall into three basic groups:
■ Fan trays and power supplies
■ Disk drives
■ PCI cards
Each group is discussed in more detail in the sections that follow.
Note – PCI and disk hot-plug operations are not supported when the system ok
prompt is displayed. You can only perform these hot-plug operations while the
operating system is running.
Caution – The system controller (SC) card cannot be serviced while the system is
running. Before installing or removing a system controller card, you must power off
the system and disconnect all AC power cords.
Fan Trays and Power Supplies
Sun Fire V890 fan trays and power supplies are hot-swappable—they can be
removed or inserted at any time without requiring prior software preparations. Keep
in mind that a power supply is not considered hot-swappable unless it is part of an
N+1 redundant power configuration—a system configured with the third power
supply. Do not remove a power supply from a working system if its removal would
leave the system with fewer than two working power supplies.
You can install or remove a power supply or fan tray while the system is operating
at the ok prompt. However, in the case of the power supply, you must issue a
reset-all command at the ok prompt in order for the change to be recognized the
next time the operating system is booted.
Note – If you remove a power supply or fan tray while the operating system is
running, wait for an acknowledgement message on the system console before
installing a replacement part; otherwise, the environmental monitoring software will
not recognize the new device and false error conditions will result.
Caution – When hot-swapping a redundant fan tray, do not put your hand into the
empty fan tray bay. The fans in the populated bay are still spinning.
Chapter 1 Preparing to Service the System 7
For additional information, see:
■ “About Power Supplies” on page 231
■ “About Fan Trays” on page 234
Disk Drives
Sun Fire V890 internal disk drives are hot-pluggable. However, certain software
preparations are required. To perform Sun Fire V890 disk drive hot-plug operations,
you use the Solaris luxadm utility. The luxadm utility is a command-line tool for
managing intelligent storage arrays such as Sun StorEdge
arrays or Sun Fire V890 internal storage arrays.
For more information about luxadm, refer to the Sun Fire V890 Server Owner’s Guide.
For complete disk hot-plug procedures, refer to Platform Notes: Using luxadm
Software, which is available on the Sun Fire V890 Documentation CD. Refer also to
the Sun Fire V890 Server Product Notes for late-breaking details.
Caution – When hot-plugging a disk drive, after disconnecting the drive from its
backplane, allow 30 seconds or so for the drive to spin down completely before
removing it from its drive bay.

PCI Cards
On Sun Fire V890 systems, PCI cards are hot-pluggable, while the system controller
card cannot be serviced when the machine is running.
Hot-plug operations for PCI cards involve Dynamic Reconfiguration (DR). DR is an
operating system feature that provides the ability to reconfigure system hardware
while the system is running. DR lets you logically attach or detach hardware
resources within an active operating system. The main benefit of DR is that a service
provider can add or replace hardware resources with little or no impact on normal
system operations.
PCI card hot-plug procedures may involve software commands for preparing the
system prior to removing a device, and for reconfiguring the operating system after
installing a new device. In addition, certain system requirements must be met in
order for hot-plug operations to succeed.
For information about system requirements and limitations, and for detailed PCI
card hot-plug procedures, refer to the Sun Fire V890 Dynamic Reconfiguration User’s
Guide, which is available at
Hardware. Refer to the Sun Fire V890 Server Product Notes for late-breaking details.
8 Sun Fire V890 Server Service Manual • October 2005
http://docs.sun.com, under Solaris on Sun
Caution – You can hot-plug any standard PCI card that complies with PCI Hot-Plug
Specification Revision 1.1, provided a suitable software driver exists for the Solaris
Operating System, and the driver supports hot-plugging as described in the Sun Fire
V890 Dynamic Reconfiguration User’s Guide. The Sun Fire V890 system must be
running the Solaris
8 7/01 Operating System or a subsequent release that supports
Sun Fire V890 PCI hot-plug operations. Do not attempt to hot-plug a PCI card until
you are certain that its device drivers provide the proper support; otherwise, you
may cause a system panic. For a list of Sun PCI cards and device drivers that
support PCI hot-plug operations, refer to the Sun Fire V890 Server Product Notes.
Note – DR works in conjunction with (but does not require) multipathing software.
You can use multipathing software to switch I/O operations from one I/O controller
to another to prepare for DR operations. With a combination of DR and multipathing
software, you can remove, replace, or deactivate a PCI controller card with little or
no interruption to system operation. Note that this requires redundant hardware;
that is, the system must contain an alternate I/O controller that is connected to the
same devices as the card being removed or replaced. The alternate controller must
reside on a different PCI card or be integrated into the Sun Fire V890 system
motherboard or I/O board. For additional details, refer to the Sun Fire V890 Server
Owner’s Guide.
Chapter 1 Preparing to Service the System 9
PCI Hot-Plug User Interfaces
There are two different methods for performing PCI hot-plug operations on Sun Fire
V890 systems:
■ Push-button method
■ Command-line method
The push-button method relies on push buttons and status LEDs located near each
PCI slot. You can initiate a hot-plug operation by pressing the push button for the
corresponding slot. The command-line method lets you perform hot-plug operations
via a remote login session, a Remote System Control (RSC) console, or a locally
attached console. This method involves the Solaris cfgadm(1) command.
Both hot-plug methods make use of the status LEDs located near each PCI slot.
These LEDs indicate where and when it is safe to insert or remove a card, and also
show whether the operation has succeeded or failed. For additional details on hotplug status LEDs, see
Note – Regardless of the method you use, it is often necessary to perform additional
administrative steps to prepare for a hot-plug removal operation. Prior to
performing a removal operation, you must ensure that the devices residing on the
board are not currently in use. To identify and manually terminate usage of such
devices, you can use standard Solaris Operating System commands such as
mount(1M), umount(1M), swap(1M), ifconfig(1M), and ps(1).
“About PCI Slot LEDs” on page 263.
For detailed PCI hot-plug procedures, refer to the Sun Fire V890 Dynamic
Reconfiguration User’s Guide, which is available at
Solaris on Sun Hardware. Refer to the Sun Fire V890 Server Product Notes for latebreaking details.
How to Initiate a Reconfiguration Boot
After installing any new internal option or external storage device, you must
perform a reconfiguration boot so that the operating system is able to recognize any
newly installed devices. In addition, if you remove any device and do not install a
replacement device prior to rebooting the system, you must perform a
reconfiguration boot in order for the operating system to recognize the configuration
change. This requirement also applies to any component that is connected to the
system’s I
supplies.

This requirement does not apply to any component that is:
■ Installed or removed as part of a hot-plug operation
■ Installed or removed before the operating system is installed
■ Installed as an identical replacement for a component that is already recognized
by the operating system
Caution – All internal options (except disk drives and power supplies) must be
installed only by qualified service personnel.
Before You Begin
Caution – Before you power on the system, make sure that the front and side doors
and all plastic outer panels are properly installed.

5. When the diagnostics tests are completed, and the system banner is displayed on
the system console, immediately abort the boot process to access the system ok
prompt.
The system banner contains the Ethernet address and host ID.
Note – The system may take up to 30 minutes to run diagnostic tests and display
status messages before the ok prompt appears on the system console. The time
depends on the system configuration (number of CPUs, memory modules, and PCI
cards) and the standard default configuration of the OpenBoot variables, which by
default are set at diag-level=max and verbosity=normal. To customize the
standard configuration after initial power-on, refer to the OpenBoot PROM
Enhancements for Diagnostic Operation guide, which is included on the Sun Fire V890
Documentation CD.
