Precautions
–
The system is heavy even without disks installed. At least two (2) people will be required
to install the subsystem.
–
The rack cabinet into which this subsystem will be installed must support overcurrent
protection and must not be overloaded by the modules installed. Other requirements,
such as ventilation airflow, rack stabilizing features, electrical earth, and electrical
distribution, must comply with the technical specifications listed in the documentation
that came with this product.
–
All subsystems must be mounted with and supported by the rails provided and secured
in position by the four screws in the front side flanges. In no instance is a subsystem to
be mounted by the front side flanges only as this will result in the deforming of the
subsystems chassis causing unacceptably high pressures and/or /torques to be applied
to internal components resulting in various failure modes.
–
Equipment racks must be grounded.
–
System Integrators should ensure that any integrated storage solution that includes this
product has been tested and proved to meet government regulations and codes for
subjects including safety, fire, and electrical.
–
Make sure you have a soft, clean surface to place your subsystem before working on it.
Placing the system on a rough surface during servicing may damage the chassis finish.
–
Do not remove any module or component item from its anti-static bag until you are ready
to install it. Pick up and hold modules by their edges or canister. Avoid touching PCBs
and connector pins.
–
Observe all standard ESD prevention methods, e.g., wear an anti-static wristband to
prevent static electricity from damaging the electric components.
–
The RAID subsystem can be front- or rear-mounted in a variety of 19–inch-wide
(48.26 cm) racks. The slide rail mounting kits are optional.
–
Because hard drives are prone to damage due to shock and vibration during operation, all
equipment should be installed in an equipment rack prior to powering up any subsystems
or DVR's in the rack. If equipment is added, removed, or rearranged in an equipment rack
DVR's and subsystems should be power down prior to this work.
–
All disks should be removed from the subsystem prior to assembly in a rack. Only after all
equipment is installed in a rack should the disks be installed/reinstalled.
–
Hard drives must always be grasped on the drive carrier surfaces and not by the drive
surfaces (it is most critical to avoid contact with the printed circuit board or rear
connectors). Contacting the hard drive on the connector or PCB may result in ESD
damage which will yield various immediate or latent failures.
–
Drives must not be stacked on top of each other without their protective clamshells. Due
to the magnetic components within drives, stacking them directly on top of each other
can result in erasing the programmable ICs.
–
When replacing components insert them as gently as possible while assuring full
engagement. Vibration or shock can damage hard drives in the affected unit or other
units in the rack. Hard drives are very sensitive to shock and vibration, especially while in
operation and should always be handled very carefully.
–
After all equipment is installed in a rack dress the power and data cables such that power
cables are not resting against data (SCSI, IP, RS232) cables.
