4.1.2 Power On Procedure
When powering on the subsystem, please follow these steps:
Step 1.
Power on the Fibre Channel networking devices.
These devices include FC switches and any other such
device that have been connected between application
servers and your RAID subsystem. Please refer to the
documentation that came with your networking devices for
more information.
Step 2.
Power on the expansion enclosures, if applied.
If you have expansion enclosures, e.g., Rorke’s SAS
JBODs, connected to the subsystem, power on those
enclosures before powering on the managing RAID
subsystem(s).
CAUTION!
All necessary SFP transceiver and cable connections must be made
between subsystems before turning on the subsystem. If you power on the
subsystem before correctly connecting the cables, host computers may
recognize host ports only after a LIP is issued across FC nodes if host links
are configured to operate as arbitrated loops.
Step 3.
Power on the subsystem before the host computers.
To power on the subsystem please follow the procedures
below.
Using the included power cords, connect both power
sockets on the subsystem’s power supplies to the main
power source.
Power on by using the two (2) power switches on
power supplies. (See
Figure 4-1
) Each switch controls
a single PSU; therefore make sure that both switches
are turned on.
