Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use this information to help you identify potential unsafe conditions in a device that you are working on.

Each device, as it was designed and manufactured, has required safety items to protect users and service technicians from injury. The information in this section addresses only those items. Use good judgment to identify potential unsafe conditions that might be caused by unsupported alterations or attachment of unsupported features or optional devices that are not addressed in this section. If

vi Flex System x280 X6, x480 X6, and x880 X6 Compute Node Types 7903 and 4259: Installation and Service Guide

you identify an unsafe condition, you must determine how serious the hazard is and whether you must correct the problem before you work on the product.

Consider the following conditions and the safety hazards that they present: v Electrical hazards, especially primary power. Primary voltage on the frame can

cause serious or fatal electrical shock.

v Explosive hazards, such as a damaged CRT face or a bulging capacitor. v Mechanical hazards, such as loose or missing hardware.

To inspect the product for potential unsafe conditions, complete the following steps:

1. Make sure that the power is off and the power cords are disconnected.

2. Make sure that the exterior cover is not damaged, loose, or broken, and observe

any sharp edges.

3. Check the power cords: v Make sure that the third-wire ground connector is in good condition. Use a

meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.

v Make sure that the power cords are the correct type. v Make sure that the insulation is not frayed or worn.

4. Remove the cover.

5. Check for any obvious unsupported alterations. Use good judgment as to the

safety of any unsupported alterations.

6. Check inside the system for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Make sure that the power-supply cover fasteners (screws or rivets) have not

been removed or tampered with.

Guidelines for servicing electrical equipment

Observe these guidelines when you service electrical equipment. v Check the area for electrical hazards such as moist floors, nongrounded power

extension cords, and missing safety grounds.

v Use only approved tools and test equipment. Some hand tools have handles that

are covered with a soft material that does not provide insulation from live electrical current.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition. Do not use worn or broken tools or testers.

v Do not touch the reflective surface of a dental mirror to a live electrical circuit.

The surface is conductive and can cause personal injury or equipment damage if it touches a live electrical circuit.

v Some rubber floor mats contain small conductive fibers to decrease electrostatic

discharge. Do not use this type of mat to protect yourself from electrical shock.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical

outlet so that you can turn off the power quickly in the event of an electrical accident.

v Disconnect all power before you perform a mechanical inspection, work near

power supplies, or remove or install main units.

Safety vii

v Before you work on the equipment, disconnect the power cord. If you cannot

disconnect the power cord, have the customer power-off the wall box that supplies power to the equipment and lock the wall box in the off position.

v Never assume that power has been disconnected from a circuit. Check it to

make sure that it has been disconnected.

v If you have to work on equipment that has exposed electrical circuits, observe

the following precautions: – Make sure that another person who is familiar with the power-off controls is

near you and is available to turn off the power if necessary.

– When you work with powered-on electrical equipment, use only one hand.

Keep the other hand in your pocket or behind your back to avoid creating a complete circuit that could cause an electrical shock.

– When you use a tester, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on a suitable rubber mat to insulate you from grounds such as metal

floor strips and equipment frames.

v Use extreme care when you measure high voltages. v To ensure proper grounding of components such as power supplies, pumps,

blowers, fans, and motor generators, do not service these components outside of their normal operating locations.

v If an electrical accident occurs, use caution, turn off the power, and send another

person to get medical aid.

When this green LED is lit, it indicates that the hard disk drive is powered on. When flashing, this LED indicates that the drive is in use.

Chapter 1. Introduction 11

Hard disk drive status LED (yellow)

When this yellow LED is lit, it indicates that an error has occurred with the hard disk drive. The LED turns off only after the error is corrected. You can check the CMM event log to determine the source of the condition. For more information, see “Viewing event logs without restarting the compute node” on page 69.

SMP expansion connectors

Use these connectors to connect the compute node to other compute nodes to form multi-node complexes. The SMP expansion connectors come protected by a filler that you can remove. For more information, see “Installing an SMP expansion connector” on page 747.

Link error LED

When this yellow LED is lit, it indicates that a scalable link error occurred.

Link up LED

When this green LED is lit, it indicates that the compute node is connected to other compute nodes through a quick path interconnect (QPI) link.

Note: When the Link error LED is lit, indicating that a scalable partitioning error occurred, this LED is turned off.

Scaling LED

When this white LED is lit, it indicates that the compute node is part of a scalable partition. When turned off, this LED indicates that the compute node is operating independently.

Note: This LED is operational and can be lit when the compute node is installed in the chassis and is connected to power, even if the compute node is not turned on.

Fault LED

When this yellow LED is lit, it indicates that a system error has occurred in the compute node. In addition, the fault LED on the chassis system LED panel is lit. You can check the CMM event log to determine the source of the condition. For more information, see “Viewing event logs without restarting the compute node” on page 69. See also “Light path diagnostics LEDs” on page 67 for more information about the LEDs on the compute node.

The fault LED turns off only after the error is corrected.

Note: When the fault LED turns off, you should also clear the IMM event log. Use the Setup utility to clear the IMM event log.

Check log LED

When this yellow LED is lit, it indicates that a condition that causes an event to be logged in the event log has occurred. To view the IMM2 event log see “IMM event log” on page 68

The check log LED can be turned off through the CMM led command, the CMM web interface, or Flex System Manager management software (if installed).

Power button/LED

When the compute node is connected to power through the Flex System chassis, press this button to turn on or turn off the compute node.

When you press the power-control button on any compute node in a single partition (controlled by one operating system), all compute nodes in the single partition will be turned on or turned off.

Note: The power button works only if local power control is enabled for the compute node. Local power control is enabled and disabled through the CMM power command and the CMM web interface.

v For more information about the CMM power command, see the "Flex

System Chassis Management Module: Command-Line Interface

Chapter 1. Introduction 13

Reference Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/ information/topic/com.ibm.acc.cmm.doc/cli_command_power.html.

v From the CMM web interface, select Compute Nodes from the Chassis

Management menu. For more information, see the "Flex System Chassis

Management Module: User's Guide" at http://pic.dhe.ibm.com/ infocenter/flexsys/information/topic/com.ibm.acc.cmm.doc/ cmm_user_guide.html. All fields and options are described in the CMM web interface online help.

After the compute node is removed from the chassis, press and hold this button to activate the system-board LEDs (light path diagnostics). See “Compute node controls, connectors, and LEDs” on page 11 for more information.

This button is also the power LED. This green LED indicates the power status of the compute node:

v Flashing rapidly: The LED flashes rapidly for one of the following

reasons: – The compute node has been installed in a chassis. When you install

the compute node, the LED flashes rapidly for up to 90 seconds while the integrated management module II (IMM2) in the compute node is initializing and synchronizing with the chassis management module.

– Power permissions have not been assigned to the compute node

through the Chassis Management Module.

– The Flex System chassis does not have enough power to turn on the

compute node.

– The IMM2 in the compute node is not communicating with the

Chassis Management Module.

v Flashing slowly: The compute node is connected to power through the

Flex System chassis and is ready to be turned on.

v Lit continuously: The compute node is connected to power through the

Flex System chassis and is turned on.

When the compute node is on, pressing this button causes an orderly shutdown of the compute node so that it can be removed safely from the chassis. This includes shutting down the operating system (if possible) and removing power from the compute node.

If an operating system is running, you might have to press the button for approximately 4 seconds to initiate the shutdown.

Attention: Pressing the button for 4 seconds forces the operating system to shut down immediately. Data loss is possible.

KVM connector

Connect the console breakout cable to this connector (see “Console breakout cable” on page 15 for more information).

Note: It is best practice to connect the console breakout cable to only one compute node at a time in each Flex System chassis.

USB connector

Connect a USB device to this connector.

Note: It is best practice to connect a USB device to the front of only one compute node at a time in each Flex System chassis.

Use this information for details about the console breakout cable.

Attention: Use only the console breakout cable that comes with the compute node. Attempting to connect other console breakout cable types might damage the console breakout cable and the compute node.

Use the console breakout cable to connect external I/O devices to the compute node. The console breakout cable connects through the KVM connector (see “Compute node controls, connectors, and LEDs” on page 11). The console breakout cable has connectors for a display device (video), two USB connectors for a USB keyboard and mouse, and a serial interface connector.

The following illustration identifies the connectors and components on the console breakout cable.

About this task

After you connect the compute node to power through the Flex System chassis, the compute node can be started in any of the following ways:

v You can press the power button on the front of the compute node (see

“Compute node controls, connectors, and LEDs” on page 11) to start the compute node. The power button works only if local power control is enabled for the compute node. Local power control is enabled and disabled through the CMM power command and the CMM web interface.

– For more information about the CMM power command, see the "Flex System

Chassis Management Module: Command-Line Interface Reference Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/ com.ibm.acc.cmm.doc/cli_command_power.html.

– From the CMM web interface, select Compute Nodes from the Chassis

Management menu. All fields and options are described in the CMM web interface online help. For more information, see the "Flex System Chassis Management Module: User’s Guide" at http://pic.dhe.ibm.com/infocenter/ flexsys/information/topic/com.ibm.acc.cmm.doc/cmm_user_guide.html.

Notes:

Chapter 1. Introduction 15

1. Wait until the power LED on the compute node flashes slowly before you press the power button. While the IMM2 in the compute node is initializing and synchronizing with the Chassis Management Module, the power LED flashes rapidly, and the power button on the compute node does not respond. This process can take approximately 90 seconds after the compute node has been installed.

2. While the compute node is starting, the power LED on the front of the compute node is lit and does not flash. See “Compute node controls, connectors, and LEDs” on page 11 for the power LED states.

3. When you press the power-control button on any compute node in a single partition (controlled by one operating system), all compute nodes in the single partition will be turned on or turned off.

v If a power failure occurs, the Flex System chassis and the compute node can be

configured through the CMM power command and the CMM web interface to start automatically when power is restored.

– For more information about the CMM power command, see the "Flex System

v You can turn on the compute node through the Wake on LAN feature. The

compute node must be connected to power (the power LED is flashing slowly) and must be communicating with the Chassis Management Module. The operating system must support the Wake on LAN feature, and the Wake on LAN feature must be enabled through the Chassis Management Module interface.

Turning off the compute node

Use this information for details about turning off the compute node.

About this task

When you turn off the compute node, it is still connected to power through the Flex System chassis. The compute node can respond to requests from the IMM2,

16 Flex System x280 X6, x480 X6, and x880 X6 Compute Node Types 7903 and 4259: Installation and Service Guide

such as a remote request to turn on the compute node. To remove all power from the compute node, you must remove it from the Flex System chassis.

Before you turn off the compute node, shut down the operating system. See the operating-system documentation for information about shutting down the operating system.

The compute node can be turned off in any of the following ways: v The compute node can turn off automatically as part of the operating system

shutdown process (if this feature is supported by the operating system). See your operating-system documentation for more information.

v You can press the power button on the compute node (see “Compute node

controls, connectors, and LEDs” on page 11). This starts an orderly shutdown of the operating system, if this feature is supported by the operating system.

v If the operating system stops functioning, you can press and hold the power

button for more than 4 seconds to turn off the compute node.

Attention: Pressing the power button for 4 seconds forces the operating system to shut down immediately. Data loss is possible.

v When you press the power-control button on any compute node in a single

partition (controlled by one operating system), all compute nodes in the single partition will be turned on or turned off.
