1 3.5-inch hard disk drive area
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied. The
number of the installed hard disk drives in your server varies by model. The vacant hard disk drive bays are
occupied by dummy hard disk drive trays.
For server models with 12 3.5-inch hard disk drive bays, the hard disk drive bay numbers are marked on
the top edge of the front bezel.

If your server is installed in a rack cabinet, you can use the rack handles to help you slide the server out
of the rack cabinet; or use the rack handles and screws to secure the server in the rack cabinet so that
the server cannot slide out, especially in vibration-prone areas. For more information, refer to the Rack
Installation Instructions that comes with your server.
For server models with 12 3.5-inch hard disk drive bays, the front USB connectors are integrated into the left
rack handle; and the front controls and LEDs are integrated into the right rack handle.

operating system. See Chapter 4 "Turning on and turning off the server" on page 57. The power status LED
