Connecting the power cord
WARNING: To reduce the risk of electrical shock or damage to the equipment:
•
Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
•
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
•
Unplug the power cord from the power supply to disconnect power to the equipment.
Do not route the power cord where it can be walked on or pinched by items placed against it. Pay particular
attention to the plug, electrical outlet, and the point where the cord extends from the storage system.
To connect AC power cords:
1. Connect the power cords to the power supplies.
2. Connect the power cords to the AC power source.
Powering up the D6020
NOTE: Always power up the D6020 first, and then the node.
Prerequisites
All components of the D6020 are installed. For example, disk drives should be installed so that the connected host
controllers can identify and configure them at power up.
Procedure
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.
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:
a. 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 step 5.
b. If the LEDs are not green or are blinking, resolve the issue, and then continue to step 5. For more information, see
Troubleshooting.
5. Power up the nodes. For more information, see the documentation for your specific node.
Powering down the D6020
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: If installing a hot-plug device, it is not necessary to power down the D6020.
