Installing or replacing a hot-swap redundant power supply
Depending on the model, your storage product might come with one or two hot-swap redundant power
supplies. When the storage product is populated with two hot-swap redundant power supplies, the storage
product can withstand a power loss from either power supply. This helps you avoid significant interruption
to the operation of the storage product when a power supply fails. You can replace the failing hot-swap
redundant power supply without turning off the storage product.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with
one of these parts, contact a service technician.
Notes:
• To maintain the EMI integrity and cooling of the storage product, install a new power supply as soon as
you remove the failing one. Cover the other bay with a shield if you just use one power supply to provide
power.
• Use any documentation that comes with the new power supply and follow those instructions in addition
to the instructions in this topic.
Installing a hot-swap redundant power supply
Attention:
Do not open your storage product or attempt any repair before reading and understanding “Safety
information” on page iii and “Guidelines” on page 41.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
To install a hot-swap redundant power supply, do the following:
1. Touch the static-protective package that contains the new hot-swap redundant power supply to any
unpainted surface on the outside of the storage product. Then, take the new hot-swap redundant power
supply out of the package.
