Figure 6 Removal flow of a power supply

NOTE:

The device needs at least one power supply, so the chassis has a power supply slot

without a blank panel. For this slot, skip "Install the blank panel" in the figure above.

Before you remove a power supply, prepare an ESD-preventive wrist strap and a Phillips

screwdriver.

Removing the power cord

To remove the power cord:

Turn off the circuit breaker of the power cord.

Wear an ESD-preventive wrist strap, and make sure that the wrist strap makes good

skin contact and is properly grounded.

Loosen the screw that fastens the power cord, and pull the power cord out.

CAUTION:

After the circuit breaker that connects to a power supply is off, it is normal that the

LEDs on the power supply last on for a while.
