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 Client, 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

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.
