Notes on Use
The following table includes information necessary for the proper and safe operation of the disk array
unit.
WARNING
Do not use the disk array unit in an area of high humidity. If so, a fault, electrical
shock, or fire may occur.
Do not use the disk array unit in an area where inflammable gas and/or
combustible materials are placed. If so, a fire or explosion may occur.
Do not overload AC outlets with power cords. If so, a fire may occur.
Do not put heavy objects on a power cord. If so, the insulating coating of the
power cord may be damaged, fire may occur, and/or you may be electrically
shocked.
Do not install the disk array unit in a dirty or dusty environment. Remove any dust
adhering to AC outlets and the plugs of power cords. If dust remains adhering to
an AC outlet and/or plug, a fire may occur.
Do not connect the plug of a power cord to an AC outlet with a wet hand. If so, you
may be electrically shocked.
While the disk array unit can accept power in the range of 100 - 240 VAC (50/60
Hz), the power cord shipped with the disk array unit can only accept 220 – 240
VAC. Use 220 – 240 VAC (50/60 Hz) when the included power cord is used. Using
power of a different voltage may cause electric shock, smoke, and/or fire to occur.
The controller of the disk array unit contains a lithium battery. Do not remove the
lithium battery. The lithium battery may explode when it is brought close to fire or
immersed in water. Dispose of the controller according to local ordinance. Contact
your local government for details.
If the disk array unit does not operate normally due to the life of the lithium
batteries, contact your service representative. Do not disassemble the controller,
or replace or charge battery by yourself.
- iii -
CAUTION
Do not install the disk array unit and the host systems in an unsafe or unstable
manner. If so, damage may occur to the unit and/or you may be personally injured.
Do not install the disk array unit and the power cords in an area with direct sunshine
or near any apparatus generating heat such as a heater. If so, a fault may occur.
Furthermore, the insulating coating of the power cord may be melted causing fire or
electric shock to occur.
Insert the plug of a power cord to an AC outlet securely. Tightly secure the DC
power cable with the screw. Any power cord shall be routed with sufficient margin to
avoid excess strain from being applied to the plugs of the power cord or the power
cord itself. If a power cord is removed from the AC outlet during operation, data may
be lost and/or a fault may occur.
To prevent electric shocks, connect all power cords to AC outlets with earth
grounding. Connecting the earth line to a gas pipe is extremely dangerous. Never
do it.
Before connecting or removing a peripheral device from the disk array unit, turn off
all the power switches of the disk array unit and peripherals and pull out the power
cords from the AC outlets or distribution board. If you do not do so, some units may
be damaged and/or you may be electrically shocked.
To carry or reinstall the disk array unit, disconnect all cables and power cords
beforehand. If you do not do so, some units may be damaged, you may be
electrically shocked, and/or a fire may occur.
To install the unit in a rack, observe the following guidelines.
1. Temperature – Give consideration to installing the equipment in an environment
compatible with the manufacturer's recommended ambient temperature (TMRA).
2. Reduced Air Flow – Do not compromise the amount of air flow required for safe
operation of the equipment is not compromised.
3. Mechanical Loading – Do not achieve hazardous conditions due to uneven
mechanical loading.
4. Circuit Overloading – Give consideration to the connection of the equipment to the
supply circuit and the effect that overloading the circuits might have on over current
protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
5. Reliable Grounding – Maintain reliable grounding of rack-mounted equipm ent. Pay
particular attention to supply connections other than direct connections to the
branch circuit (e.g., use of power strips).
- iv -
CAUTION
Handling optical fibers
Handle optical fibers carefully and gently.
The minimum bending radius of optical fibers must be 30 mm.
Do not apply any shock (e.g., let it fall on the floor).
Attach a protective cap to all empty connectors (on the server side, too).
Keep the connector cap for future use when a cable is connected.
Dust and/or dirt may attenuate the optical power of optical fiber and cause data
errors to occur. Clean any optical fiber cable whenever it is inserted into the mating
connector as described belowe. Never clean a connector in which light is present in
the fiber.
1. Use a lint-free "wipe" that has been dipped into alcohol (use of 99%
reagent-grade alcohol is recommended).
2. Wipe immediately after with a dry lint-free wipe.
Blow-dry using a can of clean, compressed air
Handling of the DAC-DE cable
Improper handling of this cable may cause a decrease of electric characteristics and/or
mechanical destruction (disconnection). Note the following:
1. Route the cable with sufficient margin.
2. Do not apply stress to the cable (e.g., strongly pulling it).
3. Ensure a minimum bending radius of 50 mm.
Anti-static measures
Be sure to take anti-static measures (e.g., wear a wrist strap) when working with
