NB2800
User Manual for NRSW version 4.5.0.100
4. Installation
The NB2800 is designed for mounting it on a worktop or wall. Please consider the safety instructions
in chapter 2 and the environmental conditions in chapter 3.3.
The following precautions must be taken before installing a NB2800 router:
– Avoid direct solar radiation
– Protect the device from humidity, steam and aggressive fluids
– Guarantee sufficient circulation of air around the device
– The device is for indoor use only
Attention: NetModule routers are not intended for the end consumer market. The
device must be installed and commissioned by a certified expert.
4.1. Installation of Micro-SIM Cards
Up to four Micro-SIM cards can be inserted in a NB2800 router.
SIM cards can be inserted by sliding it into one of the designated slots on the front panel. You have
to push the SIM card using a small paper clip (or similar) until it snaps into place. To remove the SIM,
you will need to push it again in the same manner. The SIM card will then rebounce and can be pulled
out.
SIMs can be assigned flexibly to any modem in the system. It is also possible to switch a SIM to
a different modem during operation, for instance if you want to use another provider upon a certain
condition. However, a SIM switch usually takes about 10-20 seconds which can be bypassed (e.g.
at bootup) if SIMs are installed reasonably. Using only a single SIM with one modem, it should be
preferably placed into the SIM 1 holder. For systems which should operate two modems with two SIMs
in parallel, we recommend to assign MOB 1 to SIM 1, MOB 2 to SIM 2 and so on.
Further information about SIM configuration can be found in chapter 5.3.3.
Attention: After a SIM Switch the SIM Cover of the NB2800 router has to be mounted
again and screwed to get IP40 protection class.
4.2. Installation of the GSM/UMTS/LTE Antennas
NetModule routers will only operate efficiently in the cellular network if there is a good signal. A stub
antenna will be suitable for most applications. However, in some circumstances it might be necessary
to use remote antennas together with an extended cable to reach a better location offering an adequate
signal. In doubt, please contact us and we would be pleased to assist you in figuring out the best
matching antenna setup for your application.
Keep in mind that effects caused by Faraday cages such as large metal surfaces (elevators, machine
housings, etc.), close meshed iron constructions and others may reduce signal reception significantly.
The mounted antennas or antenna cables should be fixed with a wrench.
