5 Powering On the Storage System

 To avoid electric shocks, do not wear an ESD wrist strap when the storage system is powering on.
 Do not adjust mini SAS cable connections between enclosures after power-on. Otherwise the storage
system may become abnormal.
The power-on process takes three to five minutes. The system is completely powered on until the power
indicator of controller enclosure does not blink continually. Then the disk enclosures start power-on
automatically.
 Follow the correct power-on sequence of the storage system: switch on external power supplies → press
the power button on either controller module → switch on the Ethernet or Fibre Channel switch → switch
on the application servers.
 Follow the correct power-off sequence of the storage system: stop host services → press and hold the
power button on either controller module until the system is completely powered off (five seconds) →
disconnect the controller enclosure and the disk enclosures from their power supplies.
