Chapter 4. Canisters
4.1. Requirements for DE2000H or DE4000H canister
replacement
Before you replace a canister in a DE2000H or DE4000H array, review the
canister types and requirements.
Canister types include power supplies, power canisters, and fan canisters. NOTE: The power
supply replacement procedure is applicable for IOM replacements. To replace your IOM perform
the power supply replacement procedure.
4.1.1. Power supply
Each 12-drive or 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:
•
DE2000H/DE4000H (2U12) controller shelf
•
DE2000H/DE4000H (2U24) controller shelf
•
DE4000F flash array
•
DE120S drive shelf
•
DE240S drive shelf
The following figure shows an example DE2000H/DE4000H (2U12) controller shelf,
DE2000H/DE4000H (2U24) controller shelf, and DE4000F flash array with two power supplies
(power-fan canisters). The DE120S and DE240S drive shelves are identical, but they include I/O
modules (IOMs) instead of controller canisters.
