Chapter 4. Canisters
4.1. Requirements for DE6000H canister replacement
Before you replace a DE6000H canister, review the requirements and
considerations.
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.
4.1.1. Power supply
The power supply replacement procedure is applicable for IOM replacements. To
replace your IOM perform the power supply replacement procedure.
Each 24-drive controller shelf or drive shelf includes two power supplies with integrated fans. These
are referred to as power-fan canisters in ThinkSystem 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.
Shelf types for a power supply
You can replace a power supply in the following shelves:
•
DE6000H (2U24) controller shelf
•
DE240S drive shelf
The following figure shows an example DE6000H (2U24) controller shelf with two power supplies
(power-fan canisters). The DE240S drive shelves are identical, but they include I/O modules (IOMs)
instead of controller canisters.
