CAUTION!
Although the PSUs are redundant and a single PSU can provide
sufficient power to the system, it is advisable to turn on both power
supplies. If only one (1) PSU is operating and that PSU fails, system
downtime will occur.
Step 4.
Power on the initiators.
The servers or iSCSI initiators should be the last devices that
are turned on. Please refer to the documentation that came
with your application servers to see their own power on
procedures.

Power On Status Check
Once the subsystem has been powered on, the status of the entire
subsystem should be checked to ensure that everything is running
smoothly and that there are no complications or malfunctions.
