DANGER
vi Power Systems: Power supplies for the 9117-MMB, 9117-MMC, 9179-MHB, or 9179-MHC
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)
Safety notices vii
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.

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 failing part.
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.

Determine if you are able to perform this procedure concurrently
Attention
Note: Two power supplies must be present in the expansion unit. If one power supply fails, the
expansion unit continues to operate. If you are performing this procedure concurrently (with the power
turned on), there is a time limit. From the moment the power supply is removed, the exchange of the
power supply must be completed in less than 5 minutes. If you cannot replace the power supply in less than
5 minutes, the I/O drawer automatically shuts down.
Read the following steps, but do not perform them yet. Then decide if you are ready (and able) to
complete this repair within 5 minutes.
1. Have the replacement power supply or fan ready.
2. Remove the power supply from the expansion unit.
3. Install the fan or fans into the power supply as required for the service procedure being performed.
4. Install the power supply into the enclosure.
Note: If you are replacing a midplane or a power supply, ensure that you only replace one of these parts
at a time. If a midplane and both power supplies are replaced at the same time, the enclosure vital
product data (VPD), which is present only in these entities, is lost. The enclosure VPD is the identity of
the 5802 or 5877 enclosure.
If your system is not managed by an HMC or an SDMC, complete the following steps to remove a power
supply or fan from an expansion unit or system while the system power is turned on:

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.

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.
4. Set the power switches of any devices connected to the system to off.
5. Unplug any power cables that are attached to the unit from electrical outlets. Ensure that you unplug
power cables from peripheral devices, such as printers and expansion units.

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:
v Super administrator
v Service representative
v Operator
v Product engineer

Activating and deactivating LEDs
You can use these procedures to activate or deactivate light-emitting diodes (LEDs) using the
management console or the Advanced System Management Interface (ASMI).
For IBM Power Systems servers that contain the POWER7 processor, the LEDs can be used to identify or
verify a part that you are servicing. The error and identify function (amber) LED indicates an error and
corresponds to the location code in the system reference code (SRC). The LED is activated and
deactivated automatically.
Additionally, the following procedures can also be used to activate and deactivate LEDs.

Deactivating a system attention LED or partition LED using the management
console
You can deactivate a system attention LED or a logical partition LED if you decide that a problem is not
a high priority and you decide to repair the problem at a later time. You can do this task from the
Hardware Management Console (HMC) or the IBM Systems Director Management Console (SDMC).
If you want to be alerted if another problem occurs, you must deactivate the system attention LED so
that it can be activated again if another problem occurs.
To deactivate a system attention LED by using HMC, complete the following steps:
1. In the navigation area, open Systems management.
2. Select the server you are working on by checking the box next to its name.
3. Open Operations.
4. Open LED Status.
5. Select View System Attention. The system attention LED window opens. The selected system and its
LED state are displayed in the upper part of the window. The logical partition and its LED state are
displayed in the lower part of the window. From the system attention LED window, you can
deactivate both the system attention LED and the logical partition LED.
6. Select Deactivate System Attention LED from the Action menu. A confirmation window is displayed
that provides the following information:
v A verification that the system attention LED was deactivated.
v An indication that there still might be open problems within the system.
v An indication that you cannot activate the system attention LED.
7. Select one of the logical partitions in the lower table, and select Deactivate partition LED from the
Partition Operations menu. A confirmation window is displayed that provides the following
information:
v A verification that the logical partition LED was deactivated.
v An indication that there still might be open problems within the logical partition.
v An indication that you cannot activate the logical partition LED.
To deactivate a system attention LED by using SDMC, complete the following steps:
1. On the Welcome page, under the Resources tab, select the server.
2. Click Actions > Service and Support> Hardware> System Attention LED.
3. Click OK.
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.
