This warranty does not extend to any Infinova products which have been subject to acts of accident, misuse, abuse, neglect, improper application or installation, improper operation or maintenance, connection to an improper voltage supply or to materials which have been altered or repaired outside an authorized Infinova factory repair center.
The modules are available in either stand-alone or card unit versions. Stand-alone module Card unit The N3740 series are compatible with 9/125 micron single-mode fibers; the N3540 series are compatible with 50/125 or 62.5/125 micron multimode fibers. Camera end transmitter N3740T is compatible with monitor end receiver N3740R; Camera end transmitter N3540T is compatible with monitor end receiver N3540R.
Installation of card unit Push the card unit along the guide rails (not in spaces between the rails). There is an Infinova logo on the front panel indicating the proper orientation. Press hard to make good connection to motherboard - loud snap indicates firm connection.

Full load of N3910-18S There are 18 slots on N3910-18S. So it can mount 18 pieces of card unit. Besides N3910-18S, there are N3910-1S, N3910-2S, N3910-3S, N3910-4S and N3910-15R optional. There are 1 slot on N3910-1S, 2 slots on N3910-2S, 3 slots on N3910-3S, 4 slots on N3910-4S and 15 slots on N3910-15R respectively.
POWER SUPPLY Power supply for card unit The unit is powered by a plug-in power supply that is offered with the appropriate desk chassis or EIA 19" subrack. Power supply for stand-alone module The card unit can be converted into a stand-alone module when installing into a 1-slot chassis N3910-1S (for N3742&N3542series, and N3744&N3544 series) or 2-slot chassis N3910-2S (for N3746&N3546series, and N3748&N3548 series), that is powered by a plug-in 24VAC@1A (N3921-24A-1 for 120V;...

TYPICAL SYSTEM CONNECTION Figure 5. Typical system connection Note: For other series mentioned in this manual, the transmission connection diagrams are similar with N3744.
CABLE DIAMETER CALCULATION AND LIGHTNING & SURGE PROTECTION Relation between 24VAC Cable Diameter and Transmission Distance In general, the maximum allowable voltage loss rate is 10% for AC-powered devices. The table below shows the relationship between transmission power and maximum transmission distance under a certain specified cable diameter, on condition that the 24VAC voltage loss rate is below 10%.

Lightning & Surge Protection The product adopts multi-level anti-lightning and anti-surge technology integrated with gas discharge tube, power resistor and TVS tube. The powerful lightning and surge protection barrier effectively avoids product damage caused by various pulse signals with power below 4kV, including instantaneous lightning, surge and static.
