Replace EF300 or EF600 controller
You can replace a single controller in your EF300 or EF600 controller shelf.
About this task
When you replace a failed controller canister, you must remove the battery, power supply, DIMMs, fans, and
host interface card (HIC) from the original controller canister, and then install them in the replacement
controller canister.
Before you begin
• Review
Requirements for EF300 or EF600 controller replacement.
• Determine if you have a failed controller canister in one of 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.
What you’ll need
• A replacement controller canister with the same part number as the controller canister you are replacing.
• An ESD wristband, or you have taken other antistatic precautions.
• A flat, static free work area.
• A #1 Phillips screwdriver
• Labels to identify each cable that is connected to the controller canister.
• A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Step 1: Prepare to replace controller
Prepare to replace a failed controller canister by verifying that the replacement controller canister has the
correct FRU part number, backing up the configuration, and collecting support data.
Steps
1. Unpack the new controller canister, and set it on a flat, static-free surface.
Save the packing materials to use when shipping the failed controller canister.
2. Locate the MAC address and FRU part number labels on the back of the controller canister.

replacing.

Details area of the Recovery Guru. If you need to find this number manually, follow these steps:
a. Select Hardware.
