IBM Power Systems 7063-CR1 Service Manual page 79

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.
Procedure
1. If you are installing a new feature, ensure that you have the software that is required to support the
new feature. See IBM Prerequisite.
2. If you are installing or replacing something 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. Blue 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, or open or close a
latch.
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 steps:
