5 Powering On the Storage System

NOTICE
 To avoid electric shock, do not wear an ESD wrist strap when the storage system is powering on.
 Do not change cable connections between enclosures after power-on. Otherwise the storage system may malfunction.
 If the expansion cables are incorrectly connected, power off the device, reconnect the expansion cable, and power on
the device.
The power-on of the storage system takes 15 to 30 minutes. When the power indicator on the controller enclosure no longer
blinks, the power-on is completed.
 Follow the correct power-on sequence of the storage system: Turn on the external power supplies for each device (disk
enclosures first, then controller enclosures and NAS units). → Press the power buttons on the controller enclosures. → Power
on the switches. → (If configured) Press the power buttons on the NAS units. → Power on the application servers.
 Follow the correct power-off sequence of the storage system: Stop host services. → (If configured) Press and hold down the
power buttons (typically for 5 seconds) on the NAS units until the units are completely powered off. → Press and hold down the
power buttons (typically for 5 seconds) on the controller enclosures until the system is completely powered off. → Disconnect
the controller enclosures, disk enclosures and NAS units from their power supplies.
