4.7 Connecting DSN-5000-10 Expansion Arrays to a DSN-5210-10 or 5410-10 Primary Array To connect the first two DSN-5000-10 expansion arrays to a DSN-5000 series primary array, use the following procedure (and refer to Figure 4-5). 1. Facing the rear of the primary array, connect one end of the supplied primary array-toexpansion 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. EXP1 Connector on the Primary Array EXP0 Connector the on Primary Array Primary Array First Expansion Array Figure 4-5.

4.7
Connecting DSN-5000-10 Expansion Arrays to a DSN-5210-10 or 5410-10 Primary Array
To connect the first two DSN-5000-10 expansion arrays to a DSN-5000 series primary array,
use the following procedure (and refer to Figure 4-5).
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 connect a second expansion array, connect one end of the second supplied primary
array-to-expansion chassis cable to the left expansion connector labeled
EXP1
on the
rear of the DSN-5000 series primary array and the other end to the
HOST
connector on
the rear of the expansion array. Secure the cable connectors at both ends of the cable
to the primary array and expansion array using the thumbscrews and locking tabs.
4.
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 each
of the expansion ports on the DSN-5000 series primary array.
For optimal performance,
the number of expansion arrays should be evenly balanced across both of the expansion
ports.
5.
If your system is equipped with redundant controllers, repeat the above steps for the
redundant controllers as shown in Figure 4-5.
The DSN-5000 series 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 chassis. When connecting the
third through sixth expansion arrays, you must obtain a separate SAS-to-SAS
cable for each I/O module (available separately at no cost from D-Link).
