7410F IFL Installation and User's Guide

9. Appendix IV 7100M Chassis

The 7100M Chassis is a standard Foxcom Chassis which holds up to 6 links.
If 7410F IFL is being installed into a 7100M the following information should be
used for installing and checking the unit.

9.1 Equipment Safety

To avoid damaging your product, please observe the following:
1. Fuses: To avoid possibility of fire hazard, always replace fuses with the
same type and rating of fuse as recommended on the power supply rear
label.
In the US/Canada 1A fuses must be used (refer to page 70).
In Europe/Asia/South America 0.5A fuses must be used.
2. The input of the transmitter has an optional built-in bias for inserting DC
power up the coax to the LNB. Make certain any equipment or test
equipment connected to the transmitter input can withstand this bias.
3. The transmitter and receiver output are DC coupled and can withstand the
bias from a satellite receiver. Do not exceed 25V DC bias.
4. Do not allow any dirt or foreign material to get into the optical connector
bulkheads. This may cause damage to the polished optical connector end
faces.
5. The optical fiber jumper cable bend radius is 3 cm. Smaller radii can
cause excessive optical loss and/or fiber breakage.
6. If multiple transmitters are installed in the chassis allow sufficient room
for adequate ventilation; otherwise the units may overheat causing possible
safety hazard or equipment damage.
7. When several units are installed on one 7100M chassis, ensure that the
total units' current (including any LNB bias) does not exceed 2A per power
supply.
CAUTION
If several units in one chassis use the LNB option, the total current may
exceed 2A. Over current in this configuration and a failure of one
power supply may blow the fuse in the spare power supply.
