Installation
This chapter describes the installation procedure for the unit.
3.1
General Considerations
Rack size:
The chassis is designed to be installed in a standard 19” rack.
Ventilation:
The 4RU chassis with Telco mounting has forced air flow from front to back in the
chassis, allowing for multiple units to be stacked above each other with no space in
between. However, adequate space must be provided in front of and behind the unit
for effective ventilation to take place. For a Broadcast mounting, the airflow will be
from the back to the front.
The 1RU chassis has forced air flow from left to right side allowing for multiple units to
be stacked above each other with no space in between. However, adequate space
must be provided on the sides for effective ventilation to take place.
3.2
Connecting Power
Power supply rating:
The 4 RU chassis can be supplied with a 100-240 V AC 50/60 Hz power or -48V DC
power. The 100-240 V AC 50/60 Hz power supply is rated for maximum 325W. The
-48 V DC power is rated for maximum 300W.
The 1 RU chassis can be supplied with a 100-240 V AC 50/60 Hz power rated for
maximum 200W.
Power supply module replacement:
The 4RU can be fitted with either one or two power supply modules. Power supply
modules can be hot-swapped from the back of the unit. A chassis delivered with
single power can later be upgraded in the field by purchasing an additional power.
The 1RU chassis is delivered with single power. In case of failure, the chassis must be
returned to factory for service.
Dual power supply units:
For units with dual redundant hot-swappable power supplies, if a power fails the
remaining power supply will handle the power consumption of a full chassis. The
recommendation is to connect the two power inlets to different mains power circuits.

Connecting Input Signals
Please refer to Appendix A. Hardware Modules for module identification.
3.3.1
IP Input
The IP input module is equipped with 2 electrical connectors (RJ45) and one optical
connector (via SFP module). One of the RJ45 electrical connectors and the optical
connector are for data, while the second electrical RJ45 connector is for management.
