the power.

3. Connect the power cords to the power supplies on each module.
Note – To ensure that the controllers acknowledge each attached drive module, turn
on power to the drive modules before turning on power to the command module to
ensure that the controllers acknowledge each attached drive module.
4. Turn on both power switches on the back of each drive module.
The drives will not spin up until they receive a Start Unit command from the
controller. While the drive modules power up, the green and amber lights on the
front and the back of the modules will flash intermittently. Depending on your
configuration, the drive modules can take from 20 seconds to several minutes to
power up.
5. Turn on both power switches on the back of the command module.
A command module can take up to 30 seconds to power up and up to 15 minutes to
complete its controller battery self-test. During this time, the green and amber lights
on the front and the back of the respective module flash intermittently.
