4 Powering on and off the system

Powering up

Observe the following guidelines before powering up the D6020:
Always install all components of the D6020.
Install hard drives in the D6020 so that the connected host controllers can identify and
configure them at power up.
Always power up the D6020 first, and then the node.
To power up the D6020:
1. Complete node hardware installation and cabling. For more information, see the
documentation for your specific node.
2. Connect the SAS cables and power cords to the D6020.
3. Press and hold the Power On/Standby button.
Wait and observe the system power LED and system fans. After the D6020 powers up, the
system power LED illuminates solid green and the system fans spin to a high speed, and
then spin down to a low speed.
4. Note the status LEDs on the I/O module and do one of the following:
If the first LED for both SAS port LEDs and the middle I/O Module LED are illuminated
green and are not blinking, continue to the next step.
If the LEDs are not green or are blinking, resolve the issue, and then go to the next
step. Refer to
5. Power up the nodes. For more information, see node documentation for additional details.

Powering down

Be sure that the partner nodes are the first units to be powered down and the last to be powered
back up. Taking this precaution ensures that the system and the OS are shut down in an orderly
manner.
IMPORTANT:
To power down the D6020:
1. Power down the partner nodes. See the node documentation for additional details.
2. Press and hold the Power On/Standby button for approximately 4 seconds. This action
