Turning on the EXP3000
To turn on the power for the initial startup of the EXP3000, complete the following
steps:
1. Make sure that:
a. All cables are correctly connected.
b. Both power cords are connected into the rear of the EXP3000 and into
properly grounded electrical outlets.
c. All hard disk drives are locked securely in place.
Important: You must install a minimum of four hard disk drives for both
power supplies to operate in a redundant mode.
2. Check the system documentation for all the hardware devices that you want to
turn on and to determine the correct power-on sequence.
Note: Be sure to turn on the EXP3000 before or at the same time as you turn
on the device that contains the RAID controller.
