4.1.1 Test Data Sheet
Each OMS11 1:1 Redundancy Switch system is shipped with a Test Data Sheet. This report
contains information on the results of the Switch quality control testing. The report also includes
information pertaining to the system settings that were made at the factory. Radyne recommends
that the user save this report for future reference.
4.2 Site Considerations
Adequate site planning and preparation simplifies the installation process and results in a more
reliable system. The user should ensure that the site has adequate electrical power,
environmental controls and protection against sources of electrical radiation and interference.
4.2.1 Power Sources
The power sources should be properly grounded and as free as possible from electrical
interference. The OMS11 employs a dual redundant power supply configuration. Each power
connection on the OMS11 must be plugged into its own separate power circuit. Each circuit must
have its own independent circuit breaker.
Grounding is achieved automatically when the properly terminated power connector is inserted
into the power receptacle. This should be checked by testing that there is no voltage present
between the chassis of the Switch and the power line ground.
The protective ground must not be bypassed or defeated In any way.
Defeating the ground may result in operator Injury or damage to the
system.
