24 Chapter 4 DSN-5000 Expansion Array Layout and Installation
4.2 Expansion Array Rear Panel Components
The rear of the DSN-5000 expansion array enclosure has the following components (see
Figure 4-4):

One or two I/O modules, each containing two SAS connectors (HOST and EXP); the HOST
connector connects the expansion array to the mini-SAS connector on the back of the
DSN-5000 primary array. The EXP connector is for future use.

Power - two power receptacles and power switches are located on the left side of the
rear panel. Both power switches must be turned on.

The DSN-5000 expansion array is "HA-capable” and can be equipped with
either one or two I/O modules (DSN-500 is the second I/O module). The
redundant I/O module is required in the Expansion Array when used with a
Primary Array that is equipped with dual controllers.
4.3 Site, Safety, and Rack-Mount Considerations
All site, safety, and rack-mount considerations listed for the DSN-5000 series primary array
in Chapter 3 also apply to the DSN-5000 expansion array.
