Dell 1900 Fan Brackets, Installing the Cooling Shroud, Removing the Center Fan Bracket

Installing the Cooling Shroud

To install the cooling shroud, align the rails on the right side of the shroud with the tracks on the right chassis wall and then slowly lower the shroud straight down into the system until the fan connector engages and the latches snap into place. See Figure 3-19.
