Oracle® ZFS Storage Appliance Customer Service Manual
For ZS3-x, 7x20 Controllers, and DE2-24, Sun Disk Shelves
Removing fan modules, memory, PCIe cards, DIMMs, and USB are cold-service operations. You must shut off power from the appliance before you remove any of these components. There will be a loss of access to the storage unless the system is in a clustered configuration.
Shut down the appliance using one of the following methods:
Log in to the BUI and click the power icon on the left side of the masthead.
SSH into the storage system and issue the maintenance system poweroff command.
SSH or serial console into the service processor and issue the stop /SYS command.
Use a pen or non-conducting pointed object to press and release the Power button on the front panel.
To initiate emergency shutdown, wherein all applications and files will be closed abruptly without saving, press and hold the power button for at least four seconds until the Power/OK status indicator on the front panel flashes, indicating that the storage controller is in standby power mode.
Caution - Because 3.3 VDC standby power is always present in the system, you must unplug the power cords before accessing any cold-serviceable components.
To access internal controller components for servicing, remove the top cover.
