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 twelve 3.5-inch hard-disk-drive bays, the hard-disk-drive bay numbers are marked
on the top edge of the front bezel.

Rack handle (right)
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 twelve 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.
