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.

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 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.
