the power supply is turned off. After shutting off the power, wait for at least the amount of time specified on the drive before touching
any components.
CAUTION! Burn Hazard. Do not touch a hot drive heatsink. Failure to comply could result in minor or moderate injury. Shut off the
power to the drive when replacing the cooling fan. To prevent burns, wait at least 15 minutes and ensure the heatsink has cooled down.
