Replace a Fan (Procedure C)

DANGER! Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized bypass. Before servicing,

disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor

stays charged after the bypass is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below

50 Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the bypass is

safe. If you do work on the bypass when it is energized, it will cause serious injury or death from electrical shock.

CAUTION! Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum of 15 minutes, then make

sure that the heatsink is cool before you replace the cooling fans. If you touch a hot drive heatsink, it can burn you.

NOTICE: Use the instructions in this manual to replace the cooling fans. When you do maintenance on the fans, replace all the fans

to increase product life. If you install the fans incorrectly, it can cause damage to the drive and bypass.
