Installing the Cisco LoRaWAN Interface Module
Powering the Cisco LoRaWAN Interface Module
2. Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied grounding lug.
Note: The grounding lug and hardware used must comply with local and national electrical codes.
3. Connect the grounding lug to the device grounding screw holes using the supplied two Phillips head screws (M4
x10 mm) with lock washers. Tighten the grounding screw to 22 to 24 in-lbs (2.49 to 2.71 N-m).
4. If necessary, strip the other end of the ground wire and connect it to a reliable earth ground, such as a grounding
rod or an appropriate grounding point on a metal pole that is grounded (see Figure 3 on page 22).
Powering the Cisco LoRaWAN Interface Module
Warning: Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning: This equipment must be externally grounded using a customer-supplied ground wire before power is
applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable
grounding is available. Statement 366
Warning: Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
The Cisco LoRaWAN Interface Module supports these power sources:
 DC power – 48 VDC
 Power-over-Ethernet (PoE+, 30W)
The Cisco LoRaWAN Interface Module can be powered via the PoE+ input from an in-line power injector or a suitably
powered switch port.
Caution: Do not place the power injector in an unprotected outdoor environment because water could get into the power
injector and cause a short circuit and possible fire.
Warning: Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV)
requirements in IEC 60950 based safety standards Statement 1033
Connecting a Power Source Equipment
The Cisco LoRaWAN Interface Module supports the Power Source Equipment (PSE) which is IEEE 802.3at compatible.
Warning: To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Statement 1023
The power injector provides 54 VDC to the Cisco LoRaWAN Interface Module over the Ethernet cable and supports a
total end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the Cisco LoRaWAN Interface Module.
When your Cisco LoRaWAN Interface Module is powered by an optional power injector, follow these steps to complete
the installation:
1. Before applying PoE to the Cisco LoRaWAN Interface Module, ensure that the Cisco LoRaWAN Interface Module is
grounded (see Grounding the Device).
2. Review Table 1 on page 19 and Table 2 on page 21 to identify the components needed for the installation.
3. Connect a CAT5 or better Ethernet cable from your wired LAN network to the power injector.
Note: The installer is responsible for ensuring that powering the Cisco LoRaWAN Interface Module from this type of
power injector is allowed by local and national safety and telecommunications equipment standards.
