Observe the following precautions when working on or around your IT rack system:  
v Heavy equipment–personal injury or equipment damage might result if mishandled.  
v Always lower the leveling pads on the rack cabinet.  
v Always install stabilizer brackets on the rack cabinet.  
v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest  
devices in the bottom of the rack cabinet. Always install servers and optional devices starting  
from the bottom of the rack cabinet.  
v Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top  
of rack-mounted devices.  
v Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in  
the rack cabinet when directed to disconnect power during servicing.  
v Connect all devices installed in a rack cabinet to power devices installed in the same rack  
cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power  
device installed in a different rack cabinet.  
v An electrical outlet that is not correctly wired could place hazardous voltage on the 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.  
CAUTION  
v Do not install a unit in a rack where the internal rack ambient temperatures will exceed the  
manufacturer's recommended ambient temperature for all your rack-mounted devices.  
v Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not  
blocked or reduced on any side, front, or back of a unit used for air flow through the unit.  
v Consideration should be given to the connection of the equipment to the supply circuit so that  
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To  
provide the correct power connection to a rack, refer to the rating labels located on the  
equipment in the rack to determine the total power requirement of the supply circuit.  
v (For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets  
are not attached to the rack. Do not pull out more than one drawer at a time. The rack might  
become unstable if you pull out more than one drawer at a time.  
v (For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless  
specified by the manufacturer. Attempting to move the drawer partially or completely out of the  
rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

CAUTION:  
Removing components from the upper positions in the rack cabinet improves rack stability during  
relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a  
room or building:  
v Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack  
cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you  
received it. If this configuration is not known, you must observe the following precautions:  
– Remove all devices in the 32U position and above.  
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.  
– Ensure that there are no empty U-levels between devices installed in the rack cabinet below the  
32U level.  
v If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from  
the suite.  
v Inspect the route that you plan to take to eliminate potential hazards.  
v Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the  
documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.  
v Verify that all door openings are at least 760 x 230 mm (30 x 80 in.).  
v Ensure that all devices, shelves, drawers, doors, and cables are secure.  
v Ensure that the four leveling pads are raised to their highest position.  
v Ensure that there is no stabilizer bracket installed on the rack cabinet during movement.  
v Do not use a ramp inclined at more than 10 degrees.  
v When the rack cabinet is in the new location, complete the following steps:  
– Lower the four leveling pads.  
– Install stabilizer brackets on the rack cabinet.  
– If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest  
position to the highest position.  
v If a long-distance relocation is required, restore the rack cabinet to the configuration of the rack  
cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent.  
Also lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the  
pallet.

Power supply LEDs  
The various states of the power supply light-emitting diodes (LEDs) can be used to identify or verify a  
power supply that you are servicing.  
The power supply has three LEDs that indicate the power supply status:  
v an ac power LED (green, at the right of the 3 LEDs)  
v a dc power LED (green, in the middle of the 3 LEDs)  
v an error and identify function LED (amber, at the left of the 3 LEDs)  
To locate the power supply LEDs, look on the top or at the back of an exposed power supply. You must  
remove covers or panels to expose the power supply. Follow the instructions to remove covers or panels  
for the power supply you are working with, and then return here.  
To activate the identify function, see “Identifying a part” on page 36.  
Descriptions for the states of the power supply LEDs follow:  
v If both the ac power and dc power (green) LEDs are on solid (not flashing) and the error and identify  
function (amber) LED is off, the power supply is operating correctly.  
v If the ac power LED is on, the dc power LED is flashing, and the error and identify function (amber)  
LED is off, then the system is turned off, but the power supply is still connected to the power source.  
v If the error and identify function (amber) LED is flashing, the power supply identify function has been  
selected.

Observe the following precautions when working on or around your IT rack system:  
v Heavy equipment–personal injury or equipment damage might result if mishandled.  
v Always lower the leveling pads on the rack cabinet.  
v Always install stabilizer brackets on the rack cabinet.  
v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest  
devices in the bottom of the rack cabinet. Always install servers and optional devices starting  
from the bottom of the rack cabinet.  
v Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top  
of rack-mounted devices.  
v Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in  
the rack cabinet when directed to disconnect power during servicing.  
v Connect all devices installed in a rack cabinet to power devices installed in the same rack  
cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power  
device installed in a different rack cabinet.  
v An electrical outlet that is not correctly wired could place hazardous voltage on the 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.  
CAUTION  
v Do not install a unit in a rack where the internal rack ambient temperatures will exceed the  
manufacturer's recommended ambient temperature for all your rack-mounted devices.  
v Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not  
blocked or reduced on any side, front, or back of a unit used for air flow through the unit.  
v Consideration should be given to the connection of the equipment to the supply circuit so that  
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To  
provide the correct power connection to a rack, refer to the rating labels located on the  
equipment in the rack to determine the total power requirement of the supply circuit.  
v (For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets  
are not attached to the rack. Do not pull out more than one drawer at a time. The rack might  
become unstable if you pull out more than one drawer at a time.  
v (For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless  
specified by the manufacturer. Attempting to move the drawer partially or completely out of the  
rack might cause the rack to become unstable or cause the drawer to fall out of the rack.  
(R001)  
Before you begin a replacement or installation procedure, perform these tasks:  
1. If you are installing a new feature, ensure that you have the software required to support the new  
feature.  
To do this, go to the following Web site: IBM Prerequisite  
2. If you are performing an installation or replacement procedure that might put your data at risk,  
ensure, wherever possible, that you have a current backup of your system or logical partition  
(including operating systems, licensed programs, and data).  
3. Review the installation or replacement procedure for the feature or part.  
4. Note the significance of color on your system.  
Power supplies 35  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Blue or terra-cotta on a part of the hardware indicates a touch point where you can grip the hardware  
to remove it from or install it in the system, open or close a latch, and so on. Terra-cotta might also  
indicate that the part can be removed and replaced with the system or logical partition power on.  
5. Ensure that you have access to a medium flat-blade screwdriver, a Phillips screwdriver, and a pair of  
scissors.  
6. If parts are incorrect, missing, or visibly damaged, do the following:  
v If you are replacing a part, contact the provider of your parts or next level of support.  
v If you are installing a feature, contact one of the following service organizations:  
– The provider of your parts or next level of support.  
– In the United States, the IBM Rochester Manufacturing Automated Information Line (R–MAIL)  
at 1–800–300–8751.  
In countries and regions outside of the United States, use the following Web site to locate your service  
and support telephone numbers:  
http://www.ibm.com/planetwide  
7. If you encounter difficulties during the installation, contact your service provider, your IBM reseller,  
or your next level of support.  
8. If you are installing new hardware in a logical partition, you need to understand and plan for the  
implications of partitioning your system. For information, see Logical Partitioning.  
Identifying a part  
Use these instructions to learn how to identify the location of a failed part, the location of a part to be  
removed, or the location to install a new part on your system or expansion unit using the appropriate  
method for your system.  
For IBM Power Systems servers that contain the POWER7 processor, the light-emitting diodes (LEDs) can  
be used to identify or verify the location of a part that you are removing, servicing, or installing.  
The fault (amber) LED indicates an error and corresponds to the location code in the system reference  
code (SRC). The LED is activated and deactivated automatically.  
If you need to use the identify function, use the following procedures.  
Control panel LEDs

To stop the system or logical partition, select the appropriate procedure.  
Stopping a system that is not managed by an HMC or an SDMC  
You might need to stop the system to perform another task. Use these instructions to stop the system  
using the power button or Advanced System Management Interface.  
Before you stop the system, follow these steps:  
1. If an Integrated xSeries® Adapter (IXA) is present on the system, shut it down using IBM i options.  
2. Ensure that all jobs are completed and end all applications.  
3. Ensure that the operating system is stopped.  
Attention: Failure to do so can result in the loss of data.  
4. If a Virtual I/O Server (VIOS) logical partition is running, ensure that all clients are shut down or that  
the clients have access to their devices using an alternate method.  
The following procedure describes how to stop a system that is not managed by a Hardware  
Management Console (HMC).  
1. Log in to the system as a user with the authority to run the shutdown or pwrdwnsys (Power Down  
System) command.  
2. At the command line, enter one of the following commands:  
v If your system is running the AIX operating system, type shutdown.  
v If your system is running the Linux operating system, type shutdown -h now.  
v If your system is running the IBM i operating system, type PWRDWNSYS. If your system is partitioned,  
use the PWRDWNSYS command to power down each of the secondary partitions. Then, use the  
PWRDWNSYS command to power down the primary partition.  
The command stops the operating system. The system power turns off, the power-on light begins to  
slowly flash, and the system goes into a standby state.  
3. Record the IPL type and the IPL mode from the control panel display to help you return the system  
to this state when the installation or replacement procedure is completed.

Stopping a system by using the Hardware Management Console  
You can use the Hardware Management Console (HMC) user interface to stop the system or a logical  
partition.  
By default, the managed system is set to power off automatically when you shut down the last running  
logical partition on the managed system. If you set the managed system properties on the HMC so that  
the managed system does not power off automatically, you must use this procedure to power off your  
managed system.  
Attention: If possible, shut down the running logical partitions on the managed system before powering  
off the managed system. Powering off the managed system without shutting down the logical partitions  
first causes the logical partitions to shut down abnormally and can cause data loss. If you use a Virtual  
I/O Server (VIOS) logical partition, ensure that all clients are shut down or that the clients have access to  
their devices using an alternate method.  
To power off a managed system, you must be a member of one of the following roles:

Activating or deactivating an identify LED using the management console  
You can activate or deactivate an identify LED for components attached to the system from the Hardware  
Management Console (HMC) or the IBM Systems Director Management Console (SDMC).  
The system provides several LEDs that help identify various components, such as enclosures or  
field-replaceable units (FRUs), in the system. For this reason, they are called identify LEDs.  
You can activate or deactivate the following types of identify LEDs:  
v Identify LED for an enclosure If you want to add an adapter to a specific drawer (enclosure), you  
need to know the machine type, model, and serial number (MTMS) of the drawer. To determine  
whether you have the correct MTMS for the drawer that needs the new adapter, you can activate the  
LED for a drawer and verify that the MTMS corresponds to the drawer that requires the new adapter.

6. Select one or more FRUs from the table, and click either Activate LED or Deactivate LED. The  
associated LED is either turned on or off.  
To activate or deactivate an identify LED for an enclosure or FRU by using the SDMC, complete these  
steps:  
1. On the Welcome page, under the Resources tab, select the server.  
2. Click Actions > Service and Support> Hardware> Identify LED.  
3. To activate or deactivate an identify LED for an enclosure, select an enclosure from the table, and click  
either Activate LED or Deactivate LED. The associated LED is either turned on or off.  
4. To activate or deactivate an identify LED for a FRU, select an enclosure from the table, and then click  
List FRUs.  
5. Select one or more FRUs from the table, and then click either Activate LED or Deactivate LED. The  
associated LED is either turned on or off.  
Deactivating a system attention LED or logical partition LED using the Advanced  
System Management Interface  
You can deactivate a system attention LED or a logical partition LED using the Advanced System  
Management Interface (ASMI).  
The system attention indicator provides a visual signal that the system as a whole requires attention or  
service. Each system has a single system attention indicator. When an event occurs that either needs your  
intervention or that of service and support, the system attention indicator lights continuously. The system  
attention indicator is turned on when an entry is made in the service processor error log. The error entry  
is transmitted to the system error log and the operating system error log.  
To perform this operation, your authority level must be one of the following levels:  
v Administrator  
v Authorized service provider  
To turn off the system attention indicator, do the following steps:  
1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.  
2. In the navigation area, expand System Configuration → Service Indicators → System Attention  
Indicator.  
3. In the right pane, click Turn off system attention indicator. If the attempt is unsuccessful, an error  
message is displayed.

Activating or deactivating an identify LED using the Advanced System  
Management Interface  
You can activate or deactivate an identify LED using the Advanced System Management Interface  
(ASMI).  
You can specify the location code of any indicator to view or modify its current state. If you provide the  
wrong location code, the advanced system manager attempts to go to the next higher level of the location  
code.  
The next level is the base-level location code for that field replaceable unit (FRU). For example, a user  
types the location code for the FRU located on the second I/O slot of the third enclosure in the system. If  
the location code for the second I/O slot is incorrect (the FRU does not exist at this location), an attempt  
to set the indicator for the third enclosure is initiated. This process continues until a FRU is located or no  
other level is available.  
To perform this operation, your authority level must be one of the following levels:  
v Administrator  
v Authorized service provider  
To change the current state of an indicator, do the following steps:  
1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.  
2. In the navigation area, expand System Configuration → Service Indicators → Indicators by Location  
code.  
3. In the right pane, enter the location code of the FRU and click Continue.  
4. Select the preferred state from the list.  
5. Click Save settings.
