Appropriate labels should be already affixed to the cables or can be taken
from the section FC Cabling (SCALE) of the label sheet, see "CS800
Labelsheet" on page 93.
3. If DX100 drive enclosures are available, connect them to the controller enclosure using
the SAS cables delivered together with the system.
CAUTION!
The sequence of the DX100 storage expansion modules must be observed
precisely when they are mounted and connected to each other, see "Labels on
Front and Rear of the Storage Expansion Module" on page 82. Otherwise the
system will not work and might get damaged.
The SAS cabling of the DX100 storage modules has to be prepared in the form of a so
called reverse cabling: The cabling chain behind CM#0 of the CE module goes from the
first to the last DE while the chain behind CM#1 goes from the last to the first DE.
The last DE is the DE with the always highest identifier in the range of DE-1 to DE-a.
