Chapter 2: Hardware Installation
overloaded by the modules installed. Other requirements,
such as ventilation airflow, rack stabilizing features,
electrical earthing, and electrical distribution, must
comply with the technical specifications listed in the
documentation or safety label that came with this
product.
e. Power source and the equipment racks must be
grounded.
f. Consideration should be given to the connection of the
RAID/JBOD subsystem to the supply circuit and the
effect that overloading of circuits might bring.
g. The power source socket outlet should be installed near
the enclosure and should be easily accessible.
4. Place the enclosure on a soft, clean surface before working on it.
Placing the enclosure on a rough surface during servicing may
damage the chassis finish.
5. Do not remove any module or component from its anti-static bag
to prevent static electricity from damaging the electric
components.
6. Because hard drives are prone to damage due to shock and
vibration during operation, all hard drives should be installed in a
rack cabinet prior to powering up.
7. Drives must not be stacked on top of each other without their
protective drive trays. Even when drives are fixed in the drive
trays, contact with the exposed PCB or interface pins may result
in ESD damage which will yield immediate or latent failures.
8. Stacking drives one upon another can result in erasing the IC
programmable contents.
9. When replacing components, insert them as gently as possible
while assuring full engagement. Vibration and shock can easily
damage hard drives during operation. Handle hard drives with
extreme care.
10. Place the power cords and all cables away from foot traffic. Do
not place anything over the power cords. After the enclosure is
installed into the rack, carefully route the power cords and data
cables so that power cords are not resting against data cables.
11. If the enclosure is not used for a long time, disconnect it from
mains to avoid transient over-voltage.
12. For safety reasons, only qualified service personnel can open the
enclosure chassis.
