b) Tighten the bottom thumbscrew.
5. Return the controller shroud into place if you removed it to access the PCIe cage.

Important:
If you are upgrading to an HPE Alletra 5050 or a Nimble Storage HF60, AF60, or AF80 controller and your existing
array uses 1200W power supplies, you must upgrade to 3000W power supplies now before proceeding with
installation of the new controller. Controller upgrade kits ship with 3000W power supply units (PSUs) if required.
Before installing an HPE Alletra 5050 or Nimble Storage HF60, AF60, or AF80 controller, complete Upgrade to 3000W
Power Supplies.
6. Install the new controller.
a) Make sure the controller release lever is fully extended.
b) Slide the new controller into the chassis bay. Do not force the controller. If it does not slide in easily, remove it and
retry.
c) After the new controller is in place, return the controller release lever to its original closed position until the catch
clicks.
d) Reconnect all the cables to the new controller (as labeled from step 2.)
7. Verify that the new controller is powered on.
Once installed, the new controller powers on automatically. The controller LEDs on both the left and right side of the array
remain on. If the controller does not power on automatically, contact HPE Support.
8. Verify that the array recognizes the new controller and that the new controller is in Standby mode.
Do one of the following:
In the GUI, click Hardware, then look for the controller labeled STANDBY.
In the CLI, enter the command:ctrlr --list --array array_name, then look for the controller labeled standby.
