Step 11
Step 12
In a chassis with dual power supplies or power supplies with multiple AC inputs, connect each AC power
cord to a separate input source. In case of a power source failure, the alternate input source should still
be available.
On 8700 W power supplies, there is a relay controller switch located in the lower right quadrant of the
power supply faceplate. If you are not using the 8700 W power supply’s remote power-cycling feature
or you have the remote power-cycling feature installed and you are using a normally open (NO) relay,
make sure that the switch is in the down (DEFAULT) position otherwise the power supply will not power
up.
Turn the power switch to the on (|) position on the power supply. Switching the power switch to on also
engages a pawl that locks the power supply in the bay.
Verify the power supply operation by ensuring that the power supply front panel LEDs are in these states:
• INPUT OK LED is green
Note
On the 6000 W and the 8700 W power supplies, there is a separate INPUT LED for each AC
power cord. Only the LED for a power supply input that has an AC power cord attached will
light.
• FAN OK LED is green
• OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page E-3 for
troubleshooting information.
