5 Right rack handle
7 Left rack handle
If your server is installed in a rack cabinet, you can use the rack handles to 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.
6 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.
The hard disk drive bay numbers are marked on the top edge of the front bezel.
