Requirements for E5700 controller replacement
Before you replace an E5700 controller, review the requirements and considerations.
Each controller canister contains a controller card, a battery, and an optional host interface card (HIC).
Procedure overview
When you replace a failed controller canister, you must remove the battery and HIC, if one is installed, from the
original controller canister, and install them in the replacement controller canister.
You can determine if you have a failed controller canister in two ways:
• The Recovery Guru in SANtricity System Manager directs you to replace the controller canister.
• The amber Attention LED on the controller canister is on, indicating that the controller has a fault.
This procedure applies to IOM12 and IOM12B drive shelves.
