The appliance and the storage shelves must be turned on in a specified order. If the hardware is not turned on correctly the appliance RAID controller may not recognize some storage units.
You must turn on the hardware in the following order:
Storage Shelf
Note:
If there are multiple Storage shelves, you are required to power on the last shelf in the chain first and work back toward the head unit.

To turn on the storage shelves and the appliance
- Start with the storage shelf that is farthest from the appliance.
- Flip on the power switches on each power supply on the rear of the shelf.
- Verify that the power LED on each power module is green.
The LEDs are explained in the following table.
The following table provides LED status details about the fans, AC and DC power, and the power cooling modules (PCMs).

- Locate the LEDs on each I/O module canister.
LED indications are as follows.
The LED in the red area with the white X-mark indicates an I/O module canister fault when the LED is amber.
The LED in the ID area is blue when each module is identified.
The LED in the green area with a white checkmark is green when functions are normal.
- Locate the SAS port LEDs.
Note:
The illustration shows the LEDs for port B in the top I/O module. The LEDs for all six ports are the same.
The Fault LED is farthest from each SAS port.
The Activity LED is closest to each SAS port.
The following table describes the SAS port LEDs. The combination of both LEDs provides the status.

- Move to the front of the storage shelf.
Verify that the Power on/standby LED is green.
If the Power LED or the other two LEDs are amber, escalate the issue.
The input switch is used to set the Unit identification (ID). The display is a seven-segment display. You can reset the ID number. The values "01" to "99" are valid. The value "00" is reserved.
"00" is also the default value.
Press the input switch and hold it down for five seconds.
The switch enters a programming mode. The digit on the left side of the display begins to flash first. The flashes appear on for 0.5 seconds and off for 0.5 seconds.
Press the input switch once to increment the number by one digit.
When your first required number is reached press the switch for five seconds.
The first number is now locked.
Set the second number in the same manner that you set the first number.
If you do not want to set a second number press and hold the input switch for five seconds.
The number "0" displays.
- Locate the LEDs on each disk drive carrier.
The following table describes the disk drive carrier LEDs. The combination of both LEDs provides the status.

- Repeat these steps for each storage shelf. Let each shelf initialize before you turn on the next shelf. Initialization should take 2 minutes to 3 minutes.
- Verify that all connected storage shelves function correctly. Use the LED information in the procedure that explains how to turn on the storage shelves.
- Connect the appliance to the Power Distribution Unit in the rack. The appliance will automatically turn on when the cables are connected to the PDU.
Note:
Before you turn on the appliance, ensure that you have connected a standard video cable and keyboard to the appliance so that you can configure the remote management interface after the appliance is turned on.
- Verify that the bottom LED in all 12 disk drive slots are green.
The following table provides details of the appliance disk drive LEDs.
