Generation – Installation & Operation Manual
•
The power supply power cords must include a grounding pin and must be plugged into grounded electrical outlets.
•
Remove any jewelry or metal objects from your body, which are excellent metal conductors that can create short
circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
•
This product may be connected to an IT power system. In all cases, make sure that the unit is also reliably connected
to Earth (ground).
3.3.2 General Precautions
WARNING:
The RF connections provided with this equipment are not intended for direct connection
to any outside telecommunications network or outside cable distribution plant.
WARNING:
When the equipment is lifted by the front handles, always use both front handles for
security. Never lift this equipment using only a single front handle due to the weight of the equipment.
•
The Devices weighs up to approximately 30 lbs (13.5kg). When lifting the system, two people should lift slowly with
their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.
•
While working on the system, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can
come into contact with electrical circuits or be pulled into a cooling fan.
•
After accessing the inside of the Device, close the chassis back up and secure it to the rack unit with the retention
screws and ensure that all connections have been made.
3.3.3 Chassis Precautions
•
Determine the placement of each component in the rack before you install the rails.
•
Install the heaviest components on the bottom of the rack first, and then work up.
•
Use a regulating uninterruptible power supply (UPS) to protect the Device from power surges, voltage spikes and to
keep your system operating in case of a power failure.
•
Allow any power supply modules to cool before touching them.
3.3.4 Rack Precautions
•
Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack
resting on them.
•
In single rack installation, stabilizers should be attached to the rack. In multiple rack installations, the racks should
be coupled together.
•
Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
3.4 General Mechanical
•
The equipment will require 1RU or 2RU of vertical rack space depending on the model being installed and may
be mounted directly above or below other equipment without providing space between, however, 1RU space is
recommended to be maintained from other equipment which generates significant heat.
•
Leave enough clearance in front of the rack to enable you to work on the chassis (~25 inches) and approximately 30
inches of clearance in the back of the rack to allow for sufficient airflow and ease of servicing.
NOTE:
More general information about equipment abient temperature requirements may be found

•
Rear support of the unit is mandatory and rails for attachment to rear supports are provided. Do not use the unit
chassis to support other equipment. Alternately, if rear support rails are unavailable or impractical, install the unit on
a well supported shelf.
