AirLink LX40 Series Hardware User Guide  

The LX40 can also use Power over Ethernet. An Ethernet cable connected to a  

1

compatible network switch or router can supply power to the LX40. No connection to the  

LX40 power connector (see Figure 2-8 on page 21) is required.  

Warning: Electrical installations are potentially dangerous and should be performed by personnel  

thoroughly trained in safe electrical wiring procedures.  

Avertissement : Les installations électriques sont potentiellement dangereuses et devraient être  

effectuées par du personnel parfaitement formé aux procédures de sécurité de câblage électrique.  

The LX40 supports an operating voltage of 7 V–36 V, but because low voltage standby  

mode is enabled by default, you must supply more than 9 V at startup.  

In cases where both PoE and DC power are connected, PoE will power the LX40 when  

DC voltage is below 20 V.  

If you want to operate the router at a lower voltage, you can change the low voltage  

standby settings once the router is up and running. For more information, refer to the  

ALEOS Software Configuration User Guide (Services chapter).  

Cable Strain Relief  

Sierra Wireless recommends using cable strain relief for installations in high-vibration  

environments.  

Place the cable strain relief within 200 mm (8 in.) of the LX40 to reduce the mass of cable  

supported by the power connector under vibration. Ideally, the strain relief mounting for  

the DC cable should be attached to the same object as the LX40, so both the router and  

cable vibrate together. The strain relief should be mounted such that it does not apply  

additional stress on the power connector. The cable should not be taut and should not pull  

the power connector at an angle.  

Fusing  

For DC installations, Sierra Wireless recommends fusing the power input using a 4 A, fast  

blow fuse on the V line, recommended to have no more than 10% de-rating over the  

in  

operating temperature range.
