Before You Begin
Before going through with this manual, you should read and focus to the following safety
guidelines. Notes about the subsystem’s controller configuration and the product
packaging and delivery are also included.
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.
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 Configuration
This RAID subsystem supports 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 the subsystem and verify that the contents of the shipping carton are all
there 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.
