NOTES:
POWER LED is on to indicate that it is the primary module.
The module that you plug in first will be the primary module.
You can install hard disks, each of which is about 25.4 mm (1 inch) in thickness, to the three slots of
each PCI module. Each slot has a label describing the slot number.
Disks of the same slot number are mirrored between the groups. The figure below shows the groups
and mirroring slots.
Group 1
Group 2
Empty slots in the 3.5-inch hard disk drive bay contain dummy trays. The dummy trays are inserted
to improve the cooling effect within the device. Always insert the dummy trays in the slots in which
hard disks are not installed.
Attach an ID label indicating the slot number of installed hard disk to the handle of the hard disk.
IMPORTANT:
The ID label can be used repeatedly several times. Keep the ID label for future
use.
