PS Series 50E to 400E QuickStart Step 1. Set Up the Array Hardware Configuration
11
D. Connect Power Cables for Grounding
A PS Series array includes two power supplies. It is recommended that you
connect both power supplies to different power sources, preferably on separate
circuits.
For a highly-available power configuration, connect one power supply to an
uninterruptible power supply (UPS) system, and connect the other power supply
to a different source of power. See the table Storage Array Requirements on
page 7 for information about UPS requirements.
Attach an electrostatic wrist strap to your wrist and a grounded device before
connecting power cables.
Note: Do not turn on power to the array. At this time, the power cables are only
for grounding purposes.
To connect power cables to an array, refer to the figure shown next.
