Filling empty drive bays
Empty drive bays in the server must be filled by empty drive carriers or empty drive trays,
as appropriate. With the bezel removed, install the appropriate carrier, then replace the
bezel by snapping it into place on the front of the server. Empty drive carriers for unused
drive bays are included with your server.
