Chapter 6: Maintaining the System

NOTE: If the red TEMP LED is illuminated, either a critical or noncritical failure exists.

CAUTION: If the TEMP LED is illuminated and none of the fans is spinning, quickly power down the system until a new set of fans is available. Operating a system with inadequate air circulation can damage the components.

To remove a fan:

1.Unlock or loosen the fan from the system.

■For the C2000 model, press the locking tab and rotate the fan away from the system.

■For the C4000 model, loosen the thumb screw in the top-left and lower-right of the fan.

2.Pull the fan out and remove it from the system.

Use two hands to hold the fan after it comes out of the chassis.

WARNING: Do not place your fingers near the fans when removing the unit. The blades might still be moving.

CAUTION: Do not use the fan tray handle to carry the fan. Use the handle only to push the tray into the chassis or pull it out.

To install a fan, reverse the steps taken to remove the fan.
