ORDERING CODES

See the Price List and the Ordering Guide for the ordering codes.

PREINSTALLED LICENSES

When agreed between the customer and NEC, the IDU may have all the licenses preinstalled. Certain
functionalities are then always paid for and available for immediate use. Certain functions require
additional payment before use. See the Price List and the Ordering Guide for details.
In case of a missing license key, it has to be prepared and delivered by the factory for installation. The
following serial numbers are required and are associated with the license key:
- iPasolink 200: IDU serial number
- iPasolink 400: MC-A4 card serial number
- iPasolink 1000: serial number of TERM-M card

SAFETY ISSUES

The following presents some basic safety issues related to microwave installations.

OPEN WAVEGUIDE AND OPTICAL CONNECTORS

During the installation and operation it is important to remember at all times that any open microwave
connection (waveguide or coaxial) will radiate microwave signals. Similarly, open optical connectors may
emit invisible optical signals. These signals may damage the eye permanently if the connector is too close
to the eye. The risk is a microwave-induced cataract or laser burn damage of the retina. The damage is
similar to any burn damage and is caused by excessive heating of the tissue and occurs almost
instantaneously.
AVOID THE FRONT OF T HE ANTENNA
One should avoid the intense radiation close to any radiating aperture unless the system has been designed
for close human exposure. The appropriate national safety regulations have to be followed. Microwave
antennas may cause radiation fields exceeding the regulated limits. Working in front of an antenna should
be avoided when the transmitter is switched on.
