Replacing Components

Removing and Replacing the Fan Tray

When viewing the chassis from the noninterface processor end, the fan tray is on the far right. (See

Figure 2.) A cutout in the front of the tray provides a handle for pulling the tray out of the chassis.

An M4 Phillips screw anchors a tab on the lower left side of the tray to the interior chassis frame,

just below the right power supply ear. When the fan tray is fully inserted in the chassis, an edge

connector on the fan control board snaps into the backplane electrical connector. The bottom of the

tray is a metal runner that guides the tray along a metal track on the chassis ﬂoor. Also, a bracket on

the chassis ceiling helps guide the tray into the chassis.

page 9 to open the chassis.

Use a number 2 Phillips screwdriver to remove the M4 Phillips screw from the tab on the

lower left side of the fan tray.

Grasp the cutout handle in the front of the tray and pull the fan tray straight out of the

chassis. After the fan control board connector frees the backplane socket, the fan tray will

slide easily along the track and out of the chassis.

Place the removed fan tray in an antistatic bag for storage or return to the factory.

Hold the new fan tray in the orientation shown in Figure 6. You can hold the handle with

either your right or left hand as long as you use both hands to handle the tray. However,

when inserting the tray, there is little room between the tray and the right side of the chassis.

Keep the tray as straight as possible, or you may have trouble inserting it into the chassis.

Before inserting the fan tray, compare the hardware inside the chassis to Figure 7. The runner
