Figure 1-10. SSU-2000e Power Connections
All power supplies for the SSU-2000e are implemented on the individual modules
which increases system availability by eliminating a single point of failure in the
power supply area. On each plug-in module, diodes combine the two power sources
and provide protection from reversal of the power connections on the shelf (+ and
– reversed).
The SSU-2000e operates in an integrated ground environment. Two frame ground
connections are provided at opposite corners of the front panel on M5 studs. One
banana jack receptacle is provided on each rack mounting ear.
Antenna Connectors
The SSU-2000e contains two N-type connectors labeled ANTENNA A (J6) and
ANTENNA B (J7) to connect two external radio antennas used with the optional
GPS Input modules. These two connectors are wired into I/O slots A3 and A5,
respectively. A variety of GPS antennas are available as accessories for the
SSU-2000e as described in the SSU-2000e Technical Reference.
