DANGER
The power supply switch must be in the off position when inserting it in the
chassis. Damage to the switch could result if a live power supply is installed.
1. Ensure that the new power supply and fan assembly has the same part number
and airflow label as the power supply and fan assembly being replaced, then
install the new power supply and fan assembly in the chassis:
a.
Orient the new power supply and fan assembly with the captive screw on
the right, as shown in the figure.
CAUTION:
Do not force the installation. If the FRU does not slide in easily, ensure
that it is correctly oriented before continuing.
b. Gently push the power supply and fan assembly into the chassis until it is
firmly seated.
c. Using the Phillips screwdriver, secure the power supply and fan assembly
to the chassis by tightening in the captive screw

2. Plug the power cord in to the power supply and fan assembly and power on
the unit by pressing the AC power switch to the

3.
Verify that the LED on the new power supply and fan assembly displays a
steady green light while the switch is operating. If the LED is not a steady
green, ensure that the power supply is securely installed and seated properly.
4. Optionally, if using the Command Line Interface (CLI), enter the psShow
command at the command line prompt to display the status. Power supply and
fan assembly status can also be viewed using the Web Tools application.
