Replacing Internal Components
Before inserting the fan tray, compare the hardware inside the chassis to Figure 5-26. The
Note
runner on the bottom of the fan tray has to slide along in the track on the floor. At the same time, the
runner on the top of the tray has to slide through the notch at the top of the chassis opening, then over
the top of the card cage while staying to the left of the L-bracket on the chassis ceiling.
