INSTALLATION
Installation involves mounting the FSU module in its desired location, connecting all signal, coaxial and
power cables, and programming the module data rate and other configuration settings.
Note 1: Instructions for the 107460-1 thru -4 FSU units also apply to the following units.
108015-1 thru -4, 107460-1-1, 107460-1-2, 107460-2-2 and 107460-3-1
Note 2: Instructions for the 107460-5 FSU also apply to the 108015-5 and 107460-5-1 units.
To install the module, proceed as follows:
1.
Carefully inspect the module for any signs of shipping damage. If you suspect damage to the
module, immediately call RFL Customer Service at the number given at the bottom of this page.
2.
Check the assembly number on the front panel of the module to make sure the unit is compatible
with your interface requirement as shown in Table 1.
3.
Use Table 7 as a wiring guide for the D subminiature connector if your interface is RS-449 or
V.35. Use Table 8 as a wiring guide for the D subminiature connector if your interface is X.21 or
G.703. Use Table 9 as a wiring guide for the D subminiature connector if your interface is 120 ohm
E1. Use Table 10 as a wiring guide for the BNC connectors if your interface is 75 ohm E1. When
fastening the D subminiature connector, make sure that the screws on both ends of the mating
connector are tightened to secure the connector to the FSU front panel.
NOTE
ALL CABLING TO AND FROM THE FIBER SERVICE UNIT INTERFACE CONNECTOR
MUST UTILIZE SHIELDED TWISTED PAIR OR COAXIAL CABLE TO MINIMIZE
CROSSTALK AND INTERFERENCE FROM EXTERNAL SOURCES.
CAUTION
BEFORE ATTEMPTING TO MAKE POWER CONNECTIONS TO THE FIBER SERVICE
UNIT, MAKE SURE THAT YOUR POWER SOURCE IS COMPATIBLE WITH THE FSU. IF
THE IMPROPER VOLTAGE IS CONNECTED TO THE FSU, COMPONENT DAMAGE MAY
RESULT.
A suitably rated power disconnect device and over current protection device (e.g. fuse or circuit
breaker) must be installed between the station battery supply and the FSU power input. The
over current protective device should be rated at 0.5 to 1.5 Amps.
4.
Connect input power to the following terminals on the rear-panel terminal block connector TB1, as
shown in Figure 5, see Figure 6 and 9 for 1U chassis installation.
Station battery positive TB1-1
Station battery negative TB1-2
Ground
TB1-3
5.
Fiber optic cables with type ST series bayonet fiber optic connectors must be connected to the fiber
optic heads on the front panel of the FSU module and to the far end chassis. When connecting fiber
optic cables, make sure the connectors are properly aligned before tightening, and then fully tighten
them. This will help minimize losses in the connector.
