Rackmount System Diagram
Power supplies, historically, have the lowest MTBF of the components in a system. The Orbital Internal / External power supply configuration was designed to provide inexpensive and rapid power supply replacement. A secondary benefit is the lower operating temperature of the external power supply thus extending its life.
The external power supply needs to be 24VDC, with a minimum current rating of 1.2 Amps. It is the main power supply. If it fails, the system switches to the internal power supply. This gives the customer time to replace the external power supply without any down time or without having to take the entire rackmounted chassis in for repair.
The above offerings are available in PLL or external reference versions, and are also available in redundant configurations, either as one for one or one for two systems.
The term BDC is commonly used to refer to the modules (which look like an LNB with the waveguide removed and replaced with a connector), and to the rack-mounted unit which might contain from one to several BDC modules. BDCs are increasingly used in outdoor units at the antenna – ODUs, and have an indoor rack mounted controller – IDUs. BDCs are commonly used when a client uses multiple BDCs and a single LNA to cover the entire band.
