Chapter 4 Removal and Replacement Procedures
Removing and Installing the AC-Input Power Supplies
Step 9
Connect the other end of the power cord to an AC-input power source.
Caution
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.
Step 10
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.
Step 11
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.
Step 12
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.
