Danger:
Using power cords with a proper grounding path
Use only power cords that have a grounding path. Without a proper ground, a person who
touches the switch is in danger of receiving an electrical shock. Lack of a grounding path to
the switch can result in excessive emissions. For a translation of this statement, see

Installing a DC power supply
Important:
Installing a combination of AC-input and DC-input power supplies in the same chassis is not
supported.
The VSP 8000 Series supports two field-replaceable 800 W power supplies. One comes with the
switch and you can install a second power supply to provide redundancy and load sharing.
There are two power supply slots (PSU1 on top and PSU2 on the bottom).
• If you only have one power supply, you can install it in either PSU1 or PSU2.
• If you install a second power supply, neither one acts as a primary power supply. The two
power supplies load share equally.
Before you begin
• If you are replacing an installed power supply, see
on page 81.
• Remove the DC power supply wiring assembly before installing or removing the power
supply.
Note:
The design of the latch mechanism that secures the power supply enforces this safety
practice.
