Dell EMC Unity Series Field Upgrade Procedure

Note
x8 connections can only be made using the 4-port back-end SAS I/O module. Never
use ports 1 and 2 for x8 connections.
Procedure
l
Connect to the 4-port SAS back-end I/O module: Insert SAS cables into ports 0
and 1 or ports 2 and 3 of the 4-port SAS I/O modules in the storage processor, if
they are not connected already. For consistency and clarity, use ports 0 and 1 first.
This will create BE bus 2. The next configured x8 bus using ports 2 and 3 will
create BE 4.
a. Label a pair of mini-SAS HD cables using the black or green labels.
The labels used depend upon how the back-end ports are configured.
b. Connect the ports as follows:
n
Ensure that the SAS cable is inserted into ports 0 and 1 or ports 2 and 3 of
the SP A SAS module, located in the bottom storage processor of the DPE.

the right side of the DAE.
