5.8. Power supply
5.8.1. Swap out a power supply - DM3010H
Swapping out a power supply involves turning off, disconnecting, and removing
the impaired power supply and installing, connecting, and turning on the
replacement power supply.
All other components in the system must be functioning properly; if not, you must contact technical
support.
• The power supplies are redundant and hot-swappable.
• This procedure is written for replacing one power supply at a time.
It is a best practice to replace the power supply within two minutes of
removing it from the chassis. The system continues to function, but ONTAP
sends messages to the console about the degraded power supply until the
power supply is replaced.
• Power supplies are auto-ranging.
Steps
1. Identify the power supply you want to replace, based on console error messages or through the
LEDs on the power supplies.
2. If you are not already grounded, properly ground yourself.
3. Turn off the power supply and disconnect the power cables:
a. Turn off the power switch on the power supply.
b. Open the power cable retainer, and then unplug the power cable from the power supply.
c. Unplug the power cable from the power source.
4. Squeeze the latch on the power supply cam handle, and then open the cam handle to fully
release the power supply from the mid plane.
