NOTE:
The device needs at least one power module to provide power supply, so the chassis
has a power module slot without a blank panel. For this slot, you can skip “Install the
blank panel” in the figure above.
Before removing a power module, prepare an ESD-preventive wrist strap and a Phillips
screwdriver.
Removing the power cord
Follow these steps to remove the power cord:
1. Turn off the circuit breaker of the power cord.
2. Wear an ESD-preventive wrist strap, and make sure that the wrist strap makes good
skin contact and is properly grounded.
3. Remove the cable ties, and pull the power cord out.
CAUTION:
After the circuit breaker that connects to a power module is off, it is normal that the
LEDs on the power module last on for a while.
