Airflow and cooling
Airflow intake is through the filtered vents in the front panel, and exhaust is out through the rear
panel and the rear right-hand side. These vents must all have a clearance of at least 50 mm.
Switching on
Juggler must first be connected to an appropriate power source using the supplied IEC power
cord. The front panel power button will show a dim blue ring indicating this connection. Press and
release the power button to start the unit. The power button will show a bright blue ring and the
display panel will go through a start-up cycle before settling to status information and the Juggler
logo.
Reset
Should you need to reset the internal FPGA board only, the power button can be pressed and held
for 3 seconds then released when the blue light dims. The blue light will flash for 2 seconds before
returning to normal status.
Connecting External Equipment
To ensure best performance from the Juggler and compliance with relevant EMC regulations, this
equipment should only be used with high-quality shielded data and signal cables.
Only equipment and accessories approved to IEC 60950-1 and SELV circuits may be connected to
the unit. All equipment and accessories shall comply to the relevant standard for the port or ports
to which it is connected.
Environment
General
Juggler is intended for use in a commercial (not domestic) environment and should be operated in
a clean, dust free area (e.g. a server room). It is intended for operation in benign environments (not
subject to corrosive or explosive atmospheres, moisture or flammable gases). Units are not
protected against ingress of liquid (IPx0) or designed to be subject to excessive mechanical shock
or vibration.
Only used at altitude
not exceeding 2000 m
Only used in not-tropical
climate regions
Thermal
Do not block any of the unit’s air vents and ensure the ambient temperature around the Juggler is
compatible with the environmental characteristics stated in this document.
Particularly when mounted in a rack cabinet with front or rear doors the ambient temperature
around the unit may be higher than the ambient room temperature.
Electrical
Before connecting power to the unit, ensure the electricity supply is compatible with the electrical
ratings shown in this document and on the unit’s product label. The unit shall not be connected to
an IT (unearthed neutral) power distribution system and the mains socket-outlet used shall
connect to the building installation ground.
Juggler is connected to and disconnected from the mains supply with the IEC 60320 power
connector on the rear of the unit.
The Juggler is protected by twin (live and neutral) fuses in the IEC mains connector block. These
are the only user-serviceable part of the Juggler. If either malfunctions, both must only be replaced
by a qualified person using only F 2A H 250V, 5 × 20 mm ceramic cartridge fuses. Disconnect the
Juggler from the mains supply before releasing the clip with a suitable tool to withdraw the fuse
drawer, and replace both fuses. Push the drawer back in securely before reconnecting.
Maintenance
Air Filter
A user-serviceable air filter is located behind each of two vents on the unit’s front panel. It is
important to remove and clean or replace the filters periodically to avoid overheating.
Spare filter pads for Juggler units can be provided by 7thSense. Juggler should not be run without
filters, since accumulations of dust inside the chassis can also cause overheating.
Cleaning
External casing and the front panel should be carefully wiped with a soft cloth and antistatic
solution.
Internal maintenance
Other than the mains inlet fuses, Juggler contains no user-serviceable parts.
Warning
: Do not operate the Juggler with any covers removed as the air flow through the
unit will be compromised and may lead to overheating.
Warning
: Atom CPU CMOS battery replacement: Danger of explosion if incorrect battery
used or battery incorrectly installed. Contact your supplier for further instructions.
Any alterations to the product’s specification, e.g. additional/alternative components, may
invalidate the warranty or impact the unit’s performance. Additionally, such changes or
modifications could cause equipment no longer to comply with the relevant EMC regulations, and
void the user’s authority to operate the equipment. If in doubt, please contact your supplier.
Electrostatic discharge (ESD)
When handling electronic assemblies, take precautions to avoid electrostatic discharge (ESD)
causing damage. Precautions should include the wearing of an ESD protective wrist strap and
using antistatic bags for electronic assemblies when not installed in any equipment.
