Before you replace an EF300 or EF600 battery, review the requirements and considerations.

A battery is included with a controller and preserves cached data if the AC power fails.

Recovery Guru alerts

If the Recovery Guru in SANtricity System Manager reports one of following statuses, you must replace the affected battery:

  • Battery Failed

  • Battery Replacement Required

From SANtricity System Manager, review the details in the Recovery Guru to confirm that there is an issue with a battery and to ensure no other items must be addressed first.

Procedure overview

To protect your data, you must replace a failed battery as soon as possible.

The following is an overview of the steps to replace a battery in EF300 or EF600 controllers:

  1. Take controller offline.

  2. Remove the controller canister.

  3. Replace the battery.

  4. Replace the controller canister.

  5. Bring the controller online.

Requirements

If you plan to replace a battery, you must have:

  • A replacement battery.

  • An ESD wristband, or you have taken other antistatic precautions.

  • 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.)

    Optionally, you can use the command line interface (CLI) to perform some of the procedures. If you do not have access to the CLI, you can do one of the following:

    • For SANtricity System Manager (version 11.60 and above) — Download the CLI package (zip file) from System Manager. Go to Settings › System › Add-ons › Command Line Interface. You can then issue CLI commands from an operating system prompt, such as the DOS C: prompt.

    • For SANtricity Storage Manager/Enterprise Management Window (EMW) — Follow the instructions in the express guide to download and install the software. You can run CLI commands from the EMW by selecting Tools › Execute Script.
