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 cable connections between enclosures after power-on. Otherwise the storage
system may become abnormal.
 For a four-controller storage system, power on controller enclosure 0 and then controller enclosure 1
immediately.
The power-on process takes five to ten minutes. The system is completely powered on until the power
indicator of controller enclosure does not blink continually.
 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 → press the power
buttons on the file engine in sequence and check the indictor status → switch on the application servers.
 Follow the correct power-off sequence of the storage system: stop host services → power off file engine nodes
in sequence by using the management software and wait until all indicators are off → simultaneously press and
hold down the power buttons on both controller modules until the system is completely powered off (five
seconds) → disconnect the controller enclosure and the disk enclosures from their power supplies.
