1 Precautions
– The system is heavy even without disks installed. At least two people are required to
install the system.
– The rack cabinet into which this system 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 Section 9 Technical
Data, page 32 and in the documentation that came with this product.
– All systems 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 system to be
mounted by the front side flanges only as this will result in the deforming of the systems
chassis causing unacceptably high pressures and/or torques to be applied to internal
components resulting in various failure modes.
– 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 system 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.
– 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, RS-232) cables.
