the cables that run from the front of the unit so they are fed under the unit
and out through the back. The tray also provides the require d space
between the bottom of the unit and the n ext device in the rack (or the top
of the table) so there is adequate air flo w to cool the unit.
Caution: If you choose not to use the cable tray beneath your
unit, you must ensure that 1 3/4" (4.45 cm) of space is
open below the ONline unit to ensure adequa te
