a) Align the battery with the slot on the storage controller.
b) Slide the battery into the storage controller until the release tab clicks into place.

The bottom storage controller is installed upside down.
9. Reconnect the cables to the storage controller.
10. Push the release lever toward the chassis until it clicks into place. The storage controller is powered on.
NOTE:
When a storage controller is powered on, a one‐minute delay occurs while the storage controller prepares to
boot. During this time, the only indication that the storage controller is powered on are the LEDs on the storage
controller. After the one‐minute delay, the fans and LEDs turn on to indicate that the storage controller is starting
up.
11. In the Dell Storage Manager , make sure that the replacement storage controller is recognized and shown as up and running.
NOTE:
If the Storage Center software on the replacement storage controller is older than the software on the
existing storage controller, the storage system updates the replacement storage controller with the software
version on the existing storage controller. The Storage Center software update on the replacement storage
controller could take 15 to 45 minutes to complete.
