Chapter 4: Subsystem Connection and Operation
4.5.2 Power On Procedure
When powering on the FALCON, please follow these steps:
Step 1.
Power on the Fibre Channel connection devices.
These devices include the FC switches and any other such device that
have been connected to the subsystems. Please refer to the manual that
came with your FC devices to see their power on procedure.
Step 2.
Power on the subsystems that are not connected directly to the host
computers, if applied.
If you have cascaded RAID subsystems, power on those enclosures
before powering on the FALCON subsystem that is connected
directly to the host computer(s).
Step 3.
Power on the FALCON.
The subsystems should be powered on before the host computers. To
power on the subsystems please follow the description below.
•
Using the power cords provided in the package, connect all power
sockets on the subsystem rear panel to the main power source.
•
Turn the power switch on. (See
Figure
4-9
) One (1) power switch
controls all PSUs.

9: Power Sockets and Power Switch
CAUTION!
Although the PSUs are redundant and the subsystem can withstand a
single PSU failure, it is advisable to replace a failed PSU immediately.
The subsystem will be held in an idle state if two PSUs have already failed
in the subsystem.
Step 4.
Power on the host computers.
The host computers are the last devices that are turned on. Please refer
to the manual that came with your host computers to see their own
power on procedures.
