FT
DS3
Connect the two DS3 cables to the DS3 BNC connectors. These cables should
be marked “DS-3 IN” and “DS-3 OUT”. The system will not carry traffic (but
will be undamaged) if these couplers are reversed.
Alarms
Alarm indications in SkyZhone 45 release version 1.0 are displayed using the
LEDs on the unit front panels.
Local PC for terminal emulation
Connect a VT-100 terminal or a PC running terminal emulation software to
the DB-9 (Craft) serial port See “The management interface” on page 41 for
more information.
Ethernet interface
There is an RJ-45 10/100 BaseT Ethernet connector to the right of the BNC
connectors on the back of the IDU. This interface is reserved for network
management support.
DC power connection
The two-pin connection marked DC power connects -48 VDC (nominal)
power to the IDU. DC power supplied to this unit should come from an
external network power panel with fuse protection.
Caution: The IDU is not polarity sensitive and will operate properly
with power over the 36 to 60 VDC. No damage will occur due to
under- or over-voltage conditions up to 100 VDC.
WARNING! Do not connect DC power until the ODU is installed
and connected to the IDU and to the antenna.
AC power connection
The AC power connection accepts AC voltage over the range of 90-260 volts,
in a frequency range of 50-60 Hz.
WARNING! Do not connect AC power until the ODU is installed
and connected to the IDU and to the antenna. Do not connect
both AC power and DC power to the same IDU. The ground pin
in an AC power cord is not adequate grounding. Use the external
ground connection.
