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.
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 to each
device (disk enclosures first and then controller enclosures). → Press the power buttons on the controller
enclosures. → Power on the switch. → Power on the application servers.
 Follow the correct power-off sequence of the storage system: Stop host services. → Press and hold down the
power buttons (typically for five seconds) on the controller enclosures until the system is powered off. →
Disconnect the controller enclosures and the disk enclosures from their power supplies.
