NEC S2900 User Manual page 6

Connect or remove a peripheral device from the disk array unit after turning off all
the power supplies of the disk array unit and peripherals and pulling out the power
cords from the AC outlets. If not, some units may be broken and/or you may be
electrically shocked.
To carry or reinstall the disk array unit, disconnect all cables and power cords
beforehand. If not, some units may be broken, you may be electrically shocked,
and/or a fire may occur.
Handle optical fibers carefully and gently.
The minimum bending radius of optical fiber shall be 30 mm.
Dust and/or dirt may attenuate the optical power of optical fiber causing data errors
to occur. Clean any optical fiber cable whenever it is inserted into the mating
connector with the following procedure.
1. Blow parts cleaning gas (e.g. compressed air) to the connector of the optical fiber
cable for several seconds.
2. Wipe the connector with a non-woven cloth soaked with alcohol for several passes.
3. Apply the compressed air to the connector again.
To install the unit in a rack, observe the following guidelines.
1. TMRA – If installed in a rack, consideration should be given to installing the
equipment in an environment compatible with the TMRA.
2. Reduced Air Flow – Installation in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading – Mounting of the equipment in the rack should be such that a
hazardous condition is not created due to uneven mechanical loading.
4. Circuit Overloading – Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable grounding – Reliable grounding of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g., use of power strips).
Disposing of your used NEC product
In the European Union
EU-wide legislation as implemented in each Member State requires that used electrical and
electronic products carrying the mark (left) must be disposed of separately from normal
household waste. The equipment with this mark may include electrical accessories
(e.g. memory cards). When disposing of used NEC products, you should comply with
applicable legislation or such terms which may have been agreed between NEC and
your company regarding used products. The mark on the electrical and electronic
products only applies to the current European Union Member States.
Outside the European Union
If you wish to dispose of used electrical and electronic products outside the European Union,
please contact your local authority and ask for the correct method of disposal.
