Warnings and Certifications
RESTRICTED ACCESS LOCATION:
This equipment is intended to be installed in a RESTRICTED ACCESS
LOCATION only.
Access can only be gained by SERVICE PERSONS or by USERS
who have been instructed about the reasons for the restrictions
applied to the location and about any precautions that shall be
taken; and
Access is by an authorized person through the use of a TOOL or
lock and key, or other means of security, and is controlled by the
authority responsible for the location.
ELECTRIC SHOCK WARNING!
To Prevent Electric Shock:
1. Access to this equipment is granted only to trained operators and
service personnel who have been instructed of and fully understand
the possible hazardous conditions and the consequences of accessing
non-field-serviceable units, e.g., system backplane or power supplies.
2. Unplug the system before you move it or when it has become
damaged.
RELIABLE EARTHING!
Particular attention should be given to prepare reliable earthing with the
power supply connections other than direct connections to the branch circuit
(e.g., use of power strips). The AC power cords provide the main earth
connection. Check proper grounding before powering on the enclosure.
OVERLOADING PROTECTION!
1. The enclosure should be installed according to specifications on a
chassis label. Provide a suitable power source with electrical overload
protection.
2. Do not overload the AC supply branch circuit that provides power to the
rack. The total rack load should not exceed 80 percent of the branch
circuit rating.
BATTERY USE WARNING!
Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to local ordinance.

THERMAL PRECAUTIONS:
1. If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient.
Appropriate measures, such as increasing airflow, should be available
to maintain the temperature below 35°C.
2. The openings on the enclosure are for air convection. DO NOT COVER
THE OPENINGS.
3. To comply with safety, emission, and thermal requirements, all module
bays should be populated with plug-in modules. The system should not
be operated with the absence of any covers.
HANDLING PRECAUTIONS:
1. The system can either be installed into a standard EIA-310 19” rack
cabinet or placed on a desktop. Mechanical loading of the enclosure
should be carefully handled to avoid hazardous condition. A drop or fall
could cause injury.
2. Lay this system on a reliable surface with desktop installation. A drop or
fall can cause injury.
3. Mounting this enclosure requires two people.
4. The enclosure can weigh up to 37Lbs (17kg) without disk drives. With
disk drives loaded, the enclosure can weigh up to 60lb (24kg). A reliable
surface should be available to support this weight.
5. Disk drives should be installed after the enclosure is securely installed.
