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: Equipment Hazard. Follow cooling fan replacement instructions. The cooling fan cannot operate properly when it is installed
incorrectly and could seriously damage the drive. Follow the instructions in this manual to replace the cooling fan, making sure that the
label is on top before inserting the cooling fan into the drive. To ensure maximum useful product life, replace both cooling fans when
performing maintenance.
