To Power On the System After a Shutdown
Use this procedure to power the system on again after it has been running and then
powered off. If the system has never been powered on before, use the procedure
described in
“To Power On the Appliance and Controller Unit Initially” on page 52
or “To Power On the Appliance, Controller Unit, and Expansion Units Initially” on
page 54 .
Note –
When you power off the controller units and expansion units, wait five
seconds before you power them back on. If you power the units off and on too
quickly, unexpected results can occur.
1. Verify that all cables between the Sun StorageTek 5220 NAS Appliance, controller
units, and expansion units are secured according to the instructions in
“Connecting the Appliance to the Controller Unit” on page 44 and “Connecting a
Controller Unit to Expansion Units” on page 46 .
2. Power on each expansion unit by setting the two power supply switches to the On
position. Wait at least 30 seconds after powering on the second expansion unit, if
your system has one.
3. Power on the controller unit by setting the two power supply switches to the On
position.
4. Check that all LEDs on the controller unit’s front panels have turn solid green,
indicating good operation.
5. Check that all LEDs on the expansion unit’s front panels have turn solid green,
indicating good operation.
6. Verify that the appliance is connected to the network by checking that the green
LED on the appliance’s network connection is lit.
