Step 2.
Power on the expansion enclosures that are not
connected directly to the application servers, if applied.
If you have connected the F16F subsystem to expansion
SBODs or any external devices, power on those devices
before powering on the F16F RAID subsystem(s).
Step 3.
Power on the subsystem.
The subsystem should be powered on before the
application servers. To power on the subsystem, please
follow the description below.
Using the power cords provided in the package,
connect both power sockets on the subsystem rear
panel to the main power source.
Power on using the two (2) power switches on. (See
Figure 3-16
) Each switch controls a single PSU,
therefore make sure that both switches are turned on.
Figure 3-16: Power Sockets and Power Switches
CAUTION!
Although the PSUs come in a fault-tolerant pair and a single PSU can
provide sufficient power to the system, it is advisable to turn on both of the
PSUs. If only one (1) PSU is operating and that PSU fails, system down
time will occur.
Step 4.
Power on the application servers (host computers.)
The application servers should be the last devices that are
turned on. Please refer to related documentation for their
power-on procedures.
