This chapter describes how to prepare Oracle Database Appliance for servicing.
It includes the following topics:
The replaceable components in your system are designated as either field-replaceable units (FRUs) or customer-replaceable units (CRUs).
A part designated as an FRU must be replaced by Oracle-qualified service technician.
A part designated as a CRU can be replaced by a person who is not an Oracle-qualified service technician.
Some parts are not CRUs or FRUs. Instead, they are removed and replaced, or disconnected and reconnected as part of the procedure to replace another part. For example, the air duct is not a CRU or a FRU, but the procedure to replace the CPU includes a sub-procedure to remove and it.
These parts get their CRU or FRU status from the procedure of which they are part. Since the CPU is a FRU, removing and replacing the air duct requires an Oracle-qualified service technician.
The following table lists the replacement procedures whether they are CRUs or FRUs.

The following components are hot-swappable, which means they can be removed and replaced when the system chassis and the server nodes (also called system controllers) are powered on:
Front storage drives (HDDs and SSDs)
Rear boot drives
Fans (accessed from the rear)
Power supplies (accessed from the rear)
To service these components, see Chapter 4, Servicing Hot-Swap Components.
The following server node components require that the server node be powered off and removed from the system chassis. However, the system chassis and other server node (the server node not being serviced) can remain powered on:
Memory DIMMs
CPUs
PCIe riser
PCIe cards
Power distribution board
Server node battery
Boot disk backplane
Motherboard assembly (server node)
System controller cables
Front indicator panels
To service these components, see Chapter 5, Servicing Server Node Components.
The following system components require that the power be completely removed from the system chassis., that is, the server nodes must be powered down and the power cords must be removed from the chassis:
Disk midplane module
Power distribution board
To service these components, see Chapter 6, Servicing System Chassis Components .
This section provides important safety information. Read it before servicing Oracle Database Appliance.
 | Caution - Hazardous voltage present. Never run the system with the top cover removed. |
 | Caution - Equipment damage. Install the system top cover properly before starting the system. |
For your protection, observe the following safety precautions when setting up your equipment:
Follow all cautions, warnings, and instructions marked on the equipment and described in Important Safety Information for Sun Hardware Systems and Oracle Database Appliance Safety and Compliance Guide.
Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment's electrical rating label.
Follow the electrostatic discharge safety practices as described in this chapter.
Oracle Database Appliance can be serviced with the following tools:
Antistatic wrist strap
Antistatic mat
No. 2 10-inch Phillips screwdriver (magnetic tip recommended)
Flat blade screwdriver
Stylus or pencil (to press the Clear CMOS button)
To obtain support for your system, you need to report your product serial number. The product serial number is located on an RFID tag on the front of the system and on the Customer Information Sheet that is included with the system.
You can shut down either server node using the front panel power button, or the Oracle ILOM command line interface (CLI). Each method provides a graceful shutdown and an emergency shutdown option.
| Caution - Data loss. To avoid data loss and file system corruption, always use a graceful shutdown unless it is an emergency. |
After you have shut down the server nodes, you can power off the system.
See the following topics in this section to shut down a server node and power off the system chassis:
You must shut down the server node before you remove it from the system chassis.
Graceful shutdown: Press and release the recessed Power button on the lower left-hand corner of the server node's front panel (see the following figure [1]). This causes Advanced Configuration and Power Interface (ACPI) to perform an orderly shutdown of the system.
Emergency shutdown: Press and hold the recessed Power button on the lower left-hand corner of the server node's front panel for at least five seconds until the main power is off and the server node enters standby power mode (see the following figure [1]).
| Caution - Data loss. To avoid data loss and file system corruption, always use a graceful shutdown unless it is an emergency. |
When the server node is shut down, the Power/OK LED [2] on the server node's front panel flashes, indicating that the server node is in standby power mode.
$ssh username@ipaddress
Where username is the user ID and ipaddress is the Oracle ILOM IP address.
The default username is root, and the default password is changeme.
For a graceful shutdown, type:
-> stop /SYS
The server node shuts down gracefully.
For an emergency shutdown, type:
-> stop -f /SYS
The server node shuts down immediately.
| Caution - Data loss. To avoid data loss and file system corruption, always use a graceful shutdown unless it is an emergency. |
Shutting down both server nodes places the system in standby power mode.
Disconnecting the power cords from the system removes all power from the system.
Electrostatic discharge (ESD) sensitive devices, such as the motherboards, PCIe cards, storage drives, and memory cards, require special handling.
| Caution - Equipment damage. Follow antistatic precautions and do not touch the components along their connector edges. |
When handling components such as storage drive assemblies, circuit boards, or PCIe cards:
Attach an antistatic strap to your wrist and then to a metal area on the chassis. Following this practice equalizes the electrical potential between you and the system.
Place ESD-sensitive components on an antistatic mat. The following items can be used as an antistatic mat:
Antistatic bag used to wrap a replacement part
ESD mat
Disposable ESD mat (shipped with some replacement parts or optional system components)
You must remove the server node from the chassis to remove or replace internal server node components.
The removal procedure is the same for both server nodes.
| Caution - Data loss. To avoid data loss and file system corruption, always use a graceful shutdown unless it is an emergency. |
The latches are marked by green tabs. Pull the latches down and away from the rear to the system.
To gain access to a most of a server node's internal components, you must remove the server node's top cover.
To gain access to the power distribution board and the disk midplane board you must remove the middle section of the system's top cover.
For instructions, see Shut Down a Server Node.
| Caution - System fault. Do not remove the middle section of the system cover while the AC power cords are connected. Otherwise the fault LEDs light and a system fault is logged. |
To remove the middle section of the system's top cover, remove the captive Phillips screws that secure it to the system.
| Caution - Hazardous voltage present. Never run the system with the middle section of the system top cover removed. |
| Caution - Equipment damage. Install the system top cover properly before starting the system. |
