totally on +15V, and external power supply must be used if 15W is exceeded. LNBs can
draw up to 9W, please check the LNB’s user manual for current consumption.
The LB-EO LNB power supply connector powers only its own LNB, so each backplane
must be connected to a power supply (or daisy chained if the power can handle the total
current needed for all the LNBs). The pinning is the same as a Sublime power supply, and it
is possible to use this desktop power for the LNBs.
4.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user manual for the
sub-rack frame FR-2RU-10-2.
