with viewing the status LED indicators on the front panel. The MCPS4080 should
be oriented or shielded so that direct sunlight does not fall upon the front panel.
Fire Protection
Spectrian recommends that the MCPS4080 installation site be equipped with
smoke detectors and an automatic fire-extinguishing system. In addition, for
personnel safety, the site should be equipped with a portable halon or CO
2
fire
extinguisher.
Altitude
When installing the MCPS4080 above 5000 ft (1542 m), derate the maximum
operating temperature by 2° C per 1000 ft (304 m) above 5000 ft.
Ventilation
The MCPS4080 requires unrestricted airflow around the MCPS4080. The site
must be ventilated or air-conditioned so that ambient air does not exceed 50°
Celsius (122° F).
Ambient air quality
The MCPS4080 should be installed in a location that is free of airborne dust and
toxic or corrosive fumes.
Vibration and Noise
The MCPS4080 tolerates moderate levels of vibration and ambient noise. The
MCPS4080 should not be installed in a location subject to mechanical shocks or
vibrations conducted from nearby mechanical equipment. The MCPS4080
generates fan noise below 65 dBa during operation and no additional acoustic
treatment of the site is needed.
Lightning Protection
Spectrian recommends that all power, RF, and signal lines that connect to the
MCPS4080 be protected by approved lightning arrestors. Your local fire or safety
codes will determine the type of lightning protection required.
Grounding
Spectrian recommends that the MCPS4080 and entire equipment rack be grounded
with an engineered grounding system, including ground halo and ground rods.
2.2.2 Rack Installation Considerations
Rack Space
Multi-module MCPS4080 systems require 12U of rack space in a 21” rack.
Optional mounting hardware for other rack sizes is also available. When used, the
optional preamplifier requires an additional 2U above the shelf. Single module
shelves require 3U of rack space.
Clearance
During operation, the MCPS4080 requires front cabinet clearance for unrestricted
cooling air input, plus a minimum of 4 inches (102mm) behind the MCPS4080 to
exhaust hot air. Some additional rear clearance is desirable to accommodate routing
the RF input and output cables and the DC power cables to their connections on the
rear of the unit.
