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.

2.5-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.
