24 Chapter 3 Installing the DSN-5000 Series Primary Array
3.7 Connecting the Power Cords
The DSN-5000 series primary array has two power receptacles. Both must be used to connect
the DSN-5000 series primary array to an AC outlet:
1. Plug the female end of one power cord into one of the 3-pronged power connectors on
the back of the DSN-5000 series primary array. Plug the other end of the power cord into
a working AC outlet that is not controlled by a wall switch.
2. Repeat the previous step using the second power cable and power receptacle on the
DSN-5000 series primary array. For best results, the second power receptacle should be
on a different circuit.
Although the DSN-5000 series primary array can operate temporarily with
only one AC power connection, an audio alarm will sound until both power
supply units are powered on.
3.8 Powering-on the DSN-5000 series Primary Array
To power-on the DSN-5000 series primary array, turn on both of the rocker switches on both
power supplies at the rear of the unit. When the DSN-5000 series primary array powers-on,
the following actions occur:

The front panel Power LED turns green.

The DSN-5000 series primary array runs its power-on procedure (up to 5 minutes), after
which the READY LED on the right front bracket turns green.
After the DSN-5000 series primary array powers-on for the first time, it automatically loads
the factory-default configuration settings. If necessary, you can use the xStack Storage
Management Center to change these settings to suit your requirements. For a description of
the array’s factory-default configuration settings and how to change them, refer to the
xStack Storage Management Center Software User's Guide.
