Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Warning
Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock,
keep hands and fingers out of the power supply bays and backplane areas.
Follow these steps to remove a DC-input power supply:
Step 1
Verify that power is off to the DC circuit connected to the DC-input power supply you are removing.
Step 2
Turn the power switch to the Off (0) position on the power supply you are removing (
Figure 5-29
).
Turning the power switch off also disengages a pawl that unlocks the power supply from the chassis.
