WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply can result in serious
personal injury. Before servicing the drive, disconnect all power to the equipment. The internal capacitor remains charged even after 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.
NOTICE: Follow cooling fan and circulation fan replacement instructions. Improper fan replacement may cause damage to equipment. When
installing the replacement fan into the drive, make sure the fan is facing upwards. Replace all fans when performing maintenance to help
ensure maximum useful product life.
