or replaced.

Removing the Fan Tray Assembly

To remove the fan tray assembly, do the following:
1. Stop the system as described in "Stopping the System" on page 8.
2. Place the system into the service position as described in "Placing the Model 275 into the Service
and Operating Position" on page 6.
3. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the power source to the system is completely disconnected.
4. Remove the service access cover as described in "Removing the Service Access Cover" on page 9.
5. If your system does not contain a SCSI media device in the SCSI media-device bay, go to the next
step. To identify the SCSI media device locations, see Appendix C, "System Locations", on page 59. If
your system does contain SCSI media device, do the following:
a. Remove the front bezel as described in "Removing the Front Bezel" on page 11.
b. Press the blue media-bay-chassis latches and pull the media bay chassis forward in the system
chassis but do not remove it from the system chassis. To identify the media-bay-chassis latches,
see the illustrations in "Removing the Media Bay Chassis" on page 38.
6. Locate the fan tray, as shown in the following illustration.
7. Release the LED light-pipe plate attached to the fan tray by pressing the latch attached to the disk
drive backplane and rotating the plate up and off of the LED light pipes.
8. Pull up on the two blue locking knobs located at either end of the fan tray until you feel them unlock.
9. While holding the blue plastic tab on the back of the disk drive backplane, lift up on the end of the fan
tray that is next to the tab until it clears the tab.
10. Using the two blue locking knobs at either end of the fan tray assembly, lift it straight up and out of
the system unit.
11. If you are removing the fan tray as part of another procedure, return to that procedure. If you are
removing the fan tray because the fan tray itself is damaged or failing to operate correctly, remove the
three hot-swap system fans from the fan tray as described in "Removing a Hot-Swap System Fan" on
page 23.
