Before you begin
Warning

Warning No user-serviceable parts inside. Do not open. Statement 1073
Ensure that you have installed the cable guide before you begin the procedure. This is to properly guide and
arrange the power cords that you will attach as part of the installation. Since there are two rows of power
supply bays, the cable guide ensures that the power cords from one row of power supplies do not interfere
with the removal or replacement of modules in another row.
Procedure
Step 1 Remove the replacement power supply from its shipping packaging.
Step 2
Verify that the replacement power supply power switch is in the off (0) position.
Step 3 If installed, remove the blank power supply cover from the empty power supply bay. For information about
removing blank covers, see
for future use.

In the course of its operation the system may require more than one power supply installed and
supplying power. Should it become necessary to remove an active power supply unit from the
system, consult the user manual for proper system administration of available power. In order to
safely de-energize the power supply unit, the input power should first be turned off by activating
the rocker input power switch switch into the OFF state and the power cable physically disconnected
from the unit. The unit must then be removed from the slot and stowed safely away in a proper
antistatic bag. Care must be taken not to touch any of the exposed pins from the backplane connector.
When a replacement power supply unit is to be installed, its rocker switch must always be in the
OFF state and no input power cable be installed prior to inserting it into the slot. After the unit is
seated, the input power cable may then be installed and fastened securely before activating the input
power into the ON state with the rocker input power switch prior to energizing the unit. Statement
