4.8 Connecting DSN-5000-10 Expansion Arrays to a DSN-5110-10 Primary Array
To connect the first DSN-5000-10 expansion array to the DSN-5110-10 primary array, use the
following procedure (and refer to Figure 4-6).
1. Facing the rear of the primary array, connect one end of the supplied primary array to
expansion chassis cable (shown below in blue ) to the right expansion connector labeled
EXP0. Secure the cable to the primary array using the thumbscrews and locking tabs.
2. Connect the other end of the primary array-to-expansion chassis cable to the HOST
connector on the rear of the expansion array. Secure the cable to the expansion array
using the thumbscrews and locking tabs.

3. To attach additional expansion arrays, use a SAS-to-SAS expansion cable (shown above in
purple ) between the EXP connector on one expansion array and the HOST connector on
the next expansion array. Up to three expansion arrays can be daisy-chained from the
expansion port on the DSN-5110-10 primary array.
4. If your system is equipped with redundant controllers, repeat the above steps for the
redundant controllers as shown in Figure 4-6.
The DSN-5110-10 primary array has a mini-SAS connector, and the DSN-5000-
10 expansion chassis has a SAS connector. When making these connections,
use the primary array-to-expansion chassis cable (mini-SAS to SAS) supplied
with the DSN-5000-10 expansion array. When connecting the second through
third expansion arrays, you must obtain a separate SAS-to-SAS cable for each
I/O module (available separately at no cost from D-Link).
