Step 2.
Remove the drives:
a.
Press the release button at the top of the carrier face below the LEDs.
b.
Pull the cam handle to its fully open position to unseat the drive from the midplane, and then
gently slide the drive out of the chassis.
The drive should disengage from the chassis, allowing it to slide free of the chassis.
Attention: When removing a drive, always use two hands to support its weight.
Attention: Drives are fragile. Handle them as little as possible to prevent damage to them.
Step 3.
Align the drive from the old chassis with the same bay opening in the new chassis.
Step 4.
Gently push the drive into the chassis as far as it will go. The cam handle engages and begins to
rotate upward.
Step 5.
Firmly push the drive the rest of the way into the chassis, and then lock the cam handle by pushing
it up and against the drive holder. Be sure to close the cam handle slowly so that it aligns correctly
with the front of the drive carrier. It click when it is secure.
Step 6.
Repeat the process for the remaining drives in the system.

Installing the controller

After you install the controller module and any other components into the new chassis, boot it to a state
where you can run the interconnect diagnostic test.
About this task
For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller
module is especially important because it attempts to reboot as soon as you completely seat it in the
chassis.
