Memory
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
v
v
v
v
Ensure that all devices, shelves, drawers, doors, and cables are secure.
Ensure that the four leveling pads are raised to their highest position.
Ensure that there is no stabilizer bracket installed on the rack cabinet during movement.
Do not use a ramp inclined at more than 10 degrees.
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.

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. See 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.
26
Memory
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 website 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 PowerLinux rack 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 combination identify and fault LED (amber color) shows the location of a field replaceable unit
(FRU). When removing a FRU, first verify whether you are working on the correct FRU by using the
identify function in the management console or other user interface. When removing a FRU by using the
hardware management console, the identify function is activated and deactivated automatically at the
correct times.
The identify function causes the amber LED to flash. When you turn off the identify function, the LED
returns to the state it was previously. For parts that have a blue service button, the identify function sets
LED information for the service button so that when the button is pressed, the correct LEDs on that part
flash.
If you need to use the identify function, use the following procedures.
Control panel LEDs
Use this information as a guide to the control panel LEDs and buttons.
The control panel has LEDs that indicate various system status.

Stopping a system by using the HMC
You can use the Hardware Management Console (HMC) 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
Use the following steps to stop the system by using the HMC:
1. In the navigation area, expand the Systems Management folder.
2. Click the Servers icon.
3. In the Contents area, select the managed system.

Activating or deactivating an identify LED by using the SDMC:
The system provides several LEDs that help identify various components, such as enclosures or field
replaceable units (FRUs). 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.
v Identify LED for a FRU associated with a specified enclosure If you want to hook up a cable to a
specific I/O adapter, you can activate the LED for the adapter which is a field replaceable unit (FRU),
and then physically check to see where you should hook up the cable. This is especially useful when
you have several adapters with open ports.
To activate or deactivate an identify LED for an enclosure or FRU, follow these steps:
On the Resources tab, select the appropriate host or virtual server.
Select Actions > Service and Support > Hardware > Identify LED.
In the Identify LED, Select Enclosure window, select the system unit or enclosure.
To activate or deactivate an identify LED, click either Activate LED or Deactivate LED. The
associated LED is either turned on or off.

Activating or deactivating an identify LED by 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 from the IBM Systems Director Management Console (SDMC).
The system provides several LEDs that help identify various components in the system, such as
enclosures or field-replaceable units (FRUs). 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.
v Identify LED for a FRU associated with a specified enclosure. If you want to hook up a cable to a
specific I/O adapter, you can activate the LED for the adapter, which is a field replaceable unit (FRU),
and then physically check to see where you should connect the cable. This is especially useful when
you have several adapters with open ports.
To activate or deactivate an identify LED for an enclosure or FRU by using the HMC, follow these steps:
In the navigation area, open Systems management.
Select the server you are working on.
Click Operations > LED Status > Identify LED. The Identify LED, Select Enclosure window opens.
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.
5. To activate or deactivate an identify LED for a FRU, select an enclosure from the table, and then select
Selected > List FRUs.
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 by using
the Advanced System Management Interface
You can deactivate a system attention LED or a logical partition LED by 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 to the operating system error log.
Common procedures for installable features
65
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. In 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 by using the Advanced
System Management Interface
You can activate or deactivate an identify LED by 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.
