3. Place the system into the service position. See Placing the system into the service position.
4. Remove the front cover. See Removing the front cover for instructions.
5. Remove the service access cover. See Removing the service access cover for instructions.
6. Attach the wrist strap.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
7. Remove the media device filler, if present, as shown in the following figure.
   
8. Remove the fans and fan cage.
   Note: Although the following figures show a media device, you have already removed the media device filler and your system will have an empty space until you complete all the steps.
   1. Remove the fan by squeezing or lifting the tab (A) and lifting it out of the system, as shown in the following figure.
      Figure 1. Fan removal

      
      Remove the blue air baffles as shown in the following figure.

      Remove the fan cage (B) by unscrewing the thumbscrews (A) and lifting out the fan cage.

      Note: If the thumbscrews are too tight, you might need a flat-head screwdriver to complete this step. To pull the fan cage out of the system, you might need to unplug the control panel cable to allow more space.

9. Install the rails (A) onto the media device using the two small screws (B) included with your media device. Place the rails on each side of the media device. Screw the rails into the side of the media device using the lower screw hole.
   
10. Press the media device (A) into the system until you feel the latches (B) lock in place as shown.
    Note: You need to attach the media cables (A) and (B) provided at the back of the device before installing the media device.
    
11. Attach the media-device connections (A) and (B) to the system backplane. The connection for cable (A) on the backplane is already occupied. Remove the existing cable and replace it with cable (A).
    Note: The USB connection on the front panel is now inoperative.

16. Connect the power cords to the system.
17. Start the system. See Starting the system or logical partition.
18. Configure the removable disk drive by performing the following steps:
    1. For the AIX® operating system, log in as root user.
    2. At the command line, type cfgmgr.
    3. Press Enter.
    4. To verify that the system recognizes the device, run the lsdev -Cc usbms command.
    Note: The Linux operating system automatically configures the drive as a disk drive with a name in the format sdx, for example, sda, sdb, and sdc. To verify if the system recognizes the device, enter lsusb. To find the device that is associated with the USB disk drive, enter lsscsi.
19. Verify that the media device is installed and working correctly. See Verifying the installed part.
