Tray Five to Eight
DE6900 Drive Trays
without Trunking
In the cabling configuration shown in the following figure, the controller tray is
placed on top, and the controllers are labeled as A and B. Because the DE6900 drive
trays are very heavy, they are installed starting at the bottom of the cabinet. The drive
trays are labeled from the bottom upward as 1, 2, 3, and so on.
NOTE The controller tray and the drive trays do not have to be stacked in this exact
order, and there is no requirement that you label the drive trays in this particular
sequence. Just make sure the DE6900 drive trays are at the bottom of the cabinet.
