Canisters
Canisters consist of three different types: power-fan canisters (power supplies) that supply a
redundant power source and adequate cooling in a 12-drive or 24-drive controller shelf or drive shelf;
power canisters that are used for power redundancy in a 60-drive controller shelf or drive shelf; and
fan canisters that are used for cooling the 60-drive controller shelf or drive shelf.
Overview and requirements
This topic provides an overview of the canister types and describes the requirements you need to
know about before replacing a canister.
Power supply overview
Each 24-drive controller shelf or drive shelf includes two power supplies with integrated fans. These
are referred to as
power-fan canisters
in SANtricity System Manager. If a power-fan canister fails,
you must replace it as soon as possible to ensure that the shelf has a redundant power source and
adequate cooling.
You replace a power supply in the following shelves:
• E5724 controller shelf
• DE224C drive shelf
The following figure shows an example E5724 controller shelf with two power supplies (power-fan
canisters). The DE224C drive shelves are identical, but they include I/O modules (IOMs) instead of
controller canisters.

The

topics do not describe how to replace a failed power-fan canister in a
DE1600 or DE5600 drive tray, which might be connected to the E5700 or E2800 controller shelves.
For instructions for those drive tray models, refer to
Replacing a Power-Fan Canister in the DE1600
Drive Tray or the DE5600 Drive Tray

NetApp E-Series and SANtricity Resource
