5 Powering On the Storage System
NOTICE
To avoid electric shocks, do not wear an ESD wrist strap when the storage system is powering on.
Do not adjust mini SAS HD electrical cable/optical cable connections between enclosures after power-on.
Otherwise the storage system may become abnormal.
The power-on process requires 5-15 minutes. Then the disk enclosures start power-on automatically.
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. → Switch on the switch. → Switch on the application servers.
Follow the correct power-off sequence of the storage system: Stop host services. → Press and hold down the
power buttons on the controller enclosures until the system is completely powered off (five seconds). →
Disconnect the controller enclosures and the disk enclosures from their power supplies.
