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:
• HB5100 controller shelf
• DE224C drive shelf
The following figure shows an example HB5100 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 Replace power supply 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 HB5000 or HB2000 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, available from the Fujitsu ETERNUS AB/HB Series and SANtricity Resource page.
Power canister overview
Each 60-drive controller shelf or drive shelf includes two power canisters for power redundancy.
You can replace a power canister in the following shelves:
• HB5200 controller shelves
• DE460C drive shelf
The Replace power canister topics do not describe how to replace a failed power canister in a DE6600 drive
tray, which might be connected to the controller shelf.
The following figure shows the back of a DE460C drive shelf with the two power canisters:
