Rack Installation
Power Connection
To operate the receiver, you must connect it to an AC power source. For information
about connecting the chassis to AC power, see
Appendix B - Technical Specifications
(on page 371).
As Cisco units are designed for continuous operation, some products do not have a
power switch. In this case, the mains cord and/or DC power supply cable serve(s) as
the mains disconnect device.
WARNING:
Make sure that at least one end of the power cable(s) remains
easily accessible for unplugging, if you need to switch off the unit.
For example: Ensure that the socket outlet is installed near the
product.
WARNING:
To avoid electrical shock, connect the three-prong plug on this
product to an earth-grounded three-pin socket outlet only.
Mechanical Loading
Make sure that the rack is placed on a stable surface. If the rack has stabilizing
devices, install these stabilizing devices before mounting any equipment in the rack.
WARNING:
Avoid personal injury and damage to this equipment. Mounting this equipment in the
rack should be such that a hazardous condition is not caused due to uneven mechanical
loading.
Elevated Operating Ambient Temperature
Only install this equipment in a humidity- and temperature-controlled environment
that meets the requirements given in this equipment's technical specifications.
CAUTION:
If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient temperature. Therefore,
install this equipment in an environment compatible with the manufacturer's
maximum rated ambient temperature.
