Connecting the appliance to a power source

About the power supplies

The FAS250 is shipped with two power supplies, labeled PSU1 and PSU2, respectively. Each power supply has its own AC power cord. You should have separate circuit breakers for each power supply for redundancy.

Connecting the appliance to power

To connect your appliance to a power source, complete the following steps.

Step	Action
1	Make sure that your appliance is turned off.
2	Plug the power cord for PSU1 into the power receptacle on the left connector (rear view).
3	Plug the power cord for PSU2 into the power receptacle on the right connector (rear view).
4	Fasten the power cords with the clamps.
5	Plug the other end of each power cord into a grounded AC power source.
6	Turn on the power switch for both power supplies. Note The default spin up time for all disks in the appliance is 60 seconds. Reduce this spin up time to 20 seconds by turning on the switches of both power supplies within 5 seconds of each other.
7	After turning on your system for the first time, run diagnostics to make sure the appliance is functioning properly and to diagnose any hardware problems. See the Diagnostics Guide for more information.
