b. Only if there are more than just one DE:
The IOM#0 SAS OUT port of DE-1 must be connected to the IOM#0 SAS IN port of
DE-2. If there are further DE’s they must be connected in the same way.
The IOM#0 OUT port of the always last DE remains unused.
c. The SAS port of CE CM#1 must be connected to the IOM#1 SAS IN port of the always
last DE.
d. Only if there are more than just one DE:
The IOM#1 SAS OUT port of the last DE must be connected to the IOM#1 SAS IN port
of the predecessor DE. If there are further DE’s each IOM#1 must be connected in
the same way.
The IOM#1 OUT port of DE-1 remains unused.
CAUTION!
Double check the cabling. Do not continue if you are not absolutely sure that the
cabling is correct. Otherwise booting up the device could damage the existing
configuration with the result of data loss.
External cabling of the Scale system
There are three different versions of the Scale model, which can be distinguished by the
ports respectively the PCI slots used in the server, see table "Usage of PCI Slots - Scale
System" on page 55.
Please refer to the pictures below to identify the model and to see which ports can be
