Laser Safety Information (if applicable)
The optical drive in this system unit is classified as a Class 1 level Laser product. The optical
drive has a label that identifies its classification.
The optical drive in this system unit is certified in the U.S. to conform to the requirements of the
Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21 CFR)
Subchapter J for Class 1 laser products. Elsewhere, the drive is certified to conform to the
requirements of the International Electrotechnical Commission (IEC) 60825-1: 2001 and
CENELEC EN 60825-1: 1994 for Class 1 laser products.
CAUTION
Invisible laser radiation when open. Do not stare into beam or view directly with optical
instruments.
Class 1 Laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium-arsenide laser that is nominally 30 milliwatts at 830 nanometers.
The design incorporates a combination of enclosures, electronics, and redundant interlocks
such that there is no exposure to laser radiation above a Class 1 level during normal
operation, user maintenance, or servicing conditions.
Data Integrity and Verification
W ARNING
Cray product are designed to reduce the risk of undetected data corruption or loss. However, if
unplanned outages or system failures occur, users are strongly advised to check the accuracy of the
operations performed and the data saved or transmitted by the system at the time of
outage or failure.

General Recommendations
mpor t a nt
It is mandatory to comply with the procedures, design requirements and
recommendations set out in this guide. All the standards referred to in this
guide are applicable in France. Equivalent standards must be applied and
complied with in other countries.
The construction of the Data Processing Center and the installation of ancillary facilities must
meet the level of safety required by the standards and laws in force in the country where the
equipment is to be installed and the Customer's requirements in terms of continuity of ser vice.
Site preparation must take all the following aspects into account:
•
•
•
•
•
•
•
•
•
•
•
safety of personnel,
primary / raised floor ,
suspended ceiling,
sound-proofing,
protection from sunlight,
access control,
fire protection,
water protection,
air -conditioning,
power supply,
water supply.
W ARNING
The installation of an “on-line" Uninterruptible Power Supply (UPS) is strongly recommended
to ensure continuity of service and to protect the equipment in the event of a mains failure.
Note
In the case of a water-cooled equipement installation, the customer is responsible
for supplying the complete water installation, from the water supply station through
to the water pipe outlets at the base of the cabinets. The water installation must
comply with the standards in force.
Site preparation must be completed by the pre-arranged delivery date. Any delay due to
non-completion of the site by the pre-arranged date will be considered as the Customer's
responsibility.
The Customer shall bear the cost of the works to be carried out to attain stipulated safety and
continuity of operation requirements.
On request, your Customer Service Representative can supply you with a list of the services
available for your equipment. These services include Data Processing Center site assessment
and conformity inspections.

1.2.
Deliver y Conditions
The equipment is delivered 24 hours in advance of the scheduled installation date. On
arrival, the equipment must be placed, in its packing, in the Computer Room so that it
reaches room temperature before powering up (optimum operating temperature = 22° C +
3° C, hygrometry = 50% + 5%).
W ARNING
To avoid incorrect handling, the equipment must be removed from its packing by authorized
Customer Service Engineers only.
1.3.
Carr y-In Route
The route from the unloading bay to the Computer Room must be checked to ensure that the
equipment can be carried into the premises easily and that floors can suppor t temporary
overloads.
mportant
Access doors must be at least 2.10 meters high to allow rack-mounted
equipment to be transported vertically.
CAUTION
The equipment must be transported as indicated on packing labels.
The equipment may be extremely heavy and require the use of an elevator.
The Data Processing Site manager must allocate enough personnel to ensure safe handling of
the equipment.

Data Center Layout
mpor t a nt
Site layout must provide sufficient clearance around equipment for easy
access, addition of extensions and protection from direct sunlight.
Wall and floor carpets must not to be used in the Data Processing Center .
When planning layout, the following criteria must be taken into account:
•
•
•
•
•
•
resistance of primary floors,
headroom (at least 2.50 meters high),
easy access,
exposure and location of windows and doors,
location of electrical and telephone sockets,
location of pillars and radiators.
CAUTION
It is mandatory for layout to take the safety of personnel into account. Access for stretchers
must be provided around equipment and cabinets.
Note
It is recommended to make room for the removal of packing items in the Computer
Room and ancillary premises.
1.5.
Planning Installation
Installation must be planned so that any changes and / or extensions may be implemented
with minimum service disruption. It is recommended to plan installation of the following
elements:
•
•
•
•
•
•
cabinets and equipment,
cableways,
extension cables,
power and telephone sockets,
storage cabinets,
water supply connection.
The requirements are different according to the type of the system which is going to be
installed, particularly if it is a water cooled equipment.
Note
In the case of a water--cooled equipment installation, you are advised to separate
water supply aisles (cold aisles) from cable aisles (hot aisles).

When a cooling unit is installed to supply water to water-cooled cabinets, cut-outs must be
made in the raised floor slabs to allow correct water circulation, as shown in the following
figure.
mpor t a nt
The water-cooled cabinet must be aligned with slab sides.

Service Clearance
According to cabinet model, it is mandatory to comply with the service clearance
requirements indicated in the following figures.
mpor t a nt
•
When a cabinet is equipped with a Cool Cabinet Door, more service
clearance is required as shown below.
Aisles must be at least 80 cm wide to allow passageway for stretchers.
Fullaccess to equipment is mandatory for maintenance operations.
Customers are advised to plan ahead and to provide space for
extenstions.

following sources of electrical and / or electromagnetic interference must not be located in
the immediate vicinity of the Data Processing Center:
•
•
•
high-voltage lines,
radars,
radios or other transmitters.
Equipment must not be subjected to electric / magnetic fields in excess of:
• electric field (E): 3 V/m ,
