Preparing for Service

Safety Precautions

For your protection, observe the following safety precautions when setting up your equipment:

Follow all standard cautions, warnings, and instructions marked on the equipment and described in the Oracle Server Safety and Compliance Guide and Important Safety Information for Oracle's Hardware Systems.
Ensure that the voltage and frequency of your power source match the voltage and frequency that appear on the equipment electrical rating label.
Follow the electrostatic discharge safety practices as described in Electrostatic Discharge Safety.
Disconnect both power supply cords (if necessary) before servicing components.

Note:
Power cords must be disconnected when servicing components that require cold service.

Safety Symbols

The following symbols might appear in this document. Note their meanings.

Caution:

Risk of personal injury or equipment damage. To avoid personal injury or equipment damage, follow the instructions.

Caution:

Hot surface. Avoid contact. Surfaces are hot and might cause personal injury if touched.

Caution:

Hazardous voltages are present. To reduce the risk of electric shock and danger to personal health, follow the instructions.

Electrostatic Discharge Safety

Devices that are sensitive to electrostatic discharge (ESD), such as the motherboard, PCIe cards, drives, processors, and memory DIMMs require special handling.

Caution:

The boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy components. Do not touch the components along their connector edges.

Do the following when handling ESD-sensitive components:

Use an antistatic wrist strap.

Wear an antistatic wrist strap when handling components such as drive assemblies, boards, or cards. When servicing or removing server components, disconnect the power cords from the server. Attach an antistatic strap to your wrist and to a metal area on the chassis. Following this practice equalizes the electrical potentials between you and the server.

Note:
An antistatic wrist strap is not included in the Accessory Kit for the server. However, antistatic wrist straps are included with optional components.
Use an antistatic mat.

Place ESD-sensitive components such as the motherboard, DIMMS (memory modules), and other printed circuit board (PCB) cards on an antistatic mat. The following items can be used as an antistatic mat:
- Antistatic bag used to wrap an Oracle replacement part
- Oracle ESD mat (orderable item)
- Disposable ESD mat (shipped with some replacement parts or optional system components)

FRU Key Identity Properties (KIP) Automated Update

Oracle ILOM includes a key identity properties (KIP) auto-update feature that ensures product information that is used for service entitlement and warranty coverage is accurately maintained by the server at all times, including during hardware replacement activities.

The KIP includes the server product name, product part number (PPN), and product serial number (PSN). The KIP is stored in the FRUID (field-replaceable unit identifiers) container of the three server FRUs that are designated quorum members.

The quorum members include:

Disk backplane (DBP), designated as a primary quorum member.
Motherboard (MB), designated as a backup quorum member.
Power supply (PS), designated as a backup quorum member.

When a server FRU that contains the KIP is removed and a replacement component is installed, the KIP of the replacement component is programmed by Oracle ILOM to contain the same KIP as the other two components.

Note:

Only one of the quorum members can be replaced at a time. Automated updates can be completed only when two of the three quorum members contain matching key identity properties.

Required Service Tools

The server can be serviced with the following tools:

Antistatic wrist strap
Antistatic mat(s)
No. 2 Phillips screwdriver
Torx (6 lobe) T10, T15, T25, and T30 drivers
Torque driver 12 in-lbf with T20 Torx bit (processor and heatsink installation)

Tools and Equipment For Installation

Preparing the Server for Component Replacement

Note:

When you are replace the storage drives or power supplies, not all of the procedures in this section are necessary. For more information, see the replacement procedures for those components.

Before you can remove and install components that are inside the server, you must perform the procedures in some or all of the following sections.

Powering Down the Server

Gracefully shut down the server host to prevent data from being corrupted. Performing a graceful shutdown ensures that the system is ready for restart. If the server is not responding, or you must shut down the server quickly, perform an immediate shutdown.

Note:

Some server components, such as storage drives, power supplies, fan modules, and M.2 flash SSDs are hot-pluggable. Components that are hot-pluggable do not require the server to be powered down when performing service procedures.

Determine how you want to power down the server by reviewing the following options.

Power Down the Server Gracefully Using Oracle ILOM CLI

Performing a graceful shutdown ensures that all of your data is saved and the system is ready for restart.

Log in to the server as superuser or equivalent.

Depending on the nature of the problem, you might want to view the system status or the log files or run diagnostics before you shut down the system. Refer to Oracle ILOM Documentation.
Notify affected users that the server will be powered down.
Save any open files, and quit all running applications.

Refer to your application documentation for specific information about these processes.
Log in to the Oracle ILOM command-line interface (CLI) using an Administrator account.

See Accessing Oracle ILOM.
At the Oracle ILOM prompt, shut down the operating system: stop command

-> stop /System

Note:
The stop /System command does not guarantee a system shutdown. This command is only a request to the host operating system (OS) to perform a system shutdown. To ensure a system shutdown, see Power Down the Server for Immediate Shutdown Using Oracle ILOM CLI.

The host server performs an orderly power shutdown to Standby power mode, and the System OK LED on the front panel begins blinking. See System-Level Status Indicators.
Disconnect the power and cables from the server.

See Disconnect Cables From the Server.

Caution:
When you power down the server using Oracle ILOM, the server enters Standby power mode. Power is still directed to the service processor remote management subsystem and power supply fans. To completely power off the server, you must disconnect the power cords from the power supplies.

If the server is installed in a rack with extendable slide-rails, use this procedure to extend the server to the maintenance position.

To prevent the rack from tipping forward when the server is extended, extend all rack anti-tilt mechanisms.

See Stabilize the Rack. Also refer to the Oracle Rack Cabinet 1242 User's Guide at Oracle Rack Cabinet 1242 Documentation Library.
Verify that no cables will be damaged or will interfere when the server is extended.

Although the cable management arm (CMA) that is supplied with the server is hinged to accommodate extending the server, ensure that all cables and cords are capable of extending.
From the front of the server, open and hold the left and right release latch covers in the open position.

When in an open position, the release latch covers engage the slide-rail release latches [1].

Caution:
Deploy any rack anti-tilt mechanism before releasing the slide-rail release latches.
While the release latch covers are in the open position, slowly pull the server forward until the slide-rails latch into a locked position [2].

The server is now in the extended maintenance position.

Remove the Server From the Rack

Caution:

The server weighs approximately 76 lbs (34 kg). A mechanical lift or two people are required to remove the server from the rack and carry the chassis.

Use a mechanical lift or two people to remove and transport the chassis.

Disconnect all the cables and power cords from the server.
Remove the cable management arm (CMA).

See Remove the Cable Management Arm.
Extend the server to the maintenance position.

See Extend the Server to the Maintenance Position.
From the front of the server on both sides, pull the gray slide-rail release tabs toward the front of the server, and pull the server out of the rack until it is free of the rack rails [1 and 2].

Use a mechanical lift or two people to remove the chassis from the rack and transport it.

A slide-rail release tab is located on each slide-rail.

Note:
To pull the gray slide-rail release tab, place your finger in the center of the tab, not on the end, and apply pressure as you pull the tab toward the front of the server.
Set the server on a sturdy, ESD safe work surface.

Take Antistatic Measures

Prepare an antistatic surface on which to set parts during removal and installation.
Place electrostatic discharge ESD-sensitive components such as the printed circuit boards on an antistatic mat. You can use the following items as an antistatic mat:
- Antistatic bag used to wrap a replacement part
- Oracle ESD mat (orderable item)
- Disposable ESD mat (shipped with some replacement parts or optional system components)
Attach an antistatic wrist strap.

When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Then perform procedures for servicing the server.

Note:
An antistatic wrist strap is not included in the Accessory Kit for the server. However, antistatic wrist straps might be included with options and components.

Remove the Server Top Cover

Servicing some components requires that the top cover be removed.

Ensure that AC power cords are disconnected from the server power supplies.

Note:
