Before You Begin
Before going through with this manual, you should read and focus on the following
safety guidelines. Notes about the subsystem’s controller configuration and the
product packaging and delivery are also included here.
Safety Guidelines
To provide reasonable protection against any harm on the part of the user and to
obtain maximum performance, user is advised to be aware of the following safety
guidelines particularly in handling hardware components:
Upon receiving of the product:
Place the product in its proper location.
Do not try to lift it by yourself alone. Two or more persons are needed to remove
or lift the product to its packaging. To avoid unnecessary dropping out, make
sure that somebody is around for immediate assistance.
It should be handled with care to avoid dropping that may cause damage to the
product. Always use the correct lifting procedures.
Upon installing of the product:
Ambient temperature is very important for the installation site. It must not
exceed 30◦C. Due to seasonal climate changes; regulate the installation site
temperature making it not to exceed the allowed ambient temperature.
Before plugging-in any power cords, cables and connectors, make sure that the
power switches are turned off. Disconnect first any power connection if the power
supply module is being removed from the enclosure.
Outlets must be accessible to the equipment.
All external connections should be made using shielded cables and as much as
possible should not be performed by bare hand. Using anti-static hand gloves is
recommended.
In installing each component, secure all the mounting screws and locks. Make
sure that all screws are fully tightened. Follow correctly all the listed procedures
in this manual for reliable performance.
Controller Configurations
This RAID subsystem supports both single controller configurations. The single
controller can be configured depending on the user’s requirements.
This manual will discuss single controller configuration.
Packaging, Shipment and Delivery
Before removing the subsystem from the shipping carton, you should visually
inspect the physical condition of the shipping carton.
Unpack and verify that the contents of the shipping carton are complete and in
good condition.
Exterior damage to the shipping carton may indicate that the contents of the
carton are damaged.
If any damage is found, do not remove the components; contact the dealer where
you purchased the subsystem for further instructions.
