PRE-INSTALLATION NOTES
Always pre-test the system on the bench in its intended configuration prior to installation at a
remote site. Avoid cable interconnection length in excess of 1 meter in strong RF environments.
We highly recommend installation of lightning protectors to prevent line surges from damaging
expensive components.
2.3 Rack Mount
The product is normally rack-mounted in a standard 19” cabinet. Leave space clear above (or
below) the unit for proper air ventilation of the card cage. The rack ears are typically mounted as
shown in Figure 2-1. Other mounting methods are possible by changing the orientation of the
rack ears.
