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

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

Tray

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

topics do not describe how to replace a failed power canister in a DE6600 drive
tray, which might be connected to the controller shelf.
