Figure 5-2. Installing the redundant power supply
To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
Disconnect power from the storage system by unplugging all power cords
from either the electrical outlet or storage system.
5. Plug the new AC power cord into the Redundant Power Supply, then
into a grounded AC outlet.
The Power LED on the Redundant Power Supply will be green, indicating that
there is AC power available to the new supply. The Status LED on each
supply will also be green, indicating that no fault is detected. When the LEDs
on both power supplies are green, the RA4000 is protected against power
supply failure.
This completes the installation of the Redundant Power Supply option.
