4 Rack handle (right)
6 Rack handle (left)
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. You also can 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.
5 3.5-inch-drive bays (0-3)
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.
When you install drives, follow the order of the drive bay numbers.
