This tutorial teaches how to assemble an Open Radio Station, and package it if necessary (to sell it on shop.rapid.space).
Check you have one "AMARI NR Small Cell" and one "AMARI 4G 5G CORE D" before assembling the ORS.
If you don't have enough tokens on your machine, run the ors-add-token command and copy paste the tokens you got from Rapid.Space operators.
If you need to remove a token you can do the following command: sudo gedit /opt/ors-assembly/tokens
laptop:~# cd WORKDIR/slapos-device-configuration/cli
laptop:~/WORKDIR/slapos-deivce-configuration/cli# ./flash_image.py flash --re6st-token RE6ST_TOKEN --slapos-token SLAPOS_TOKEN ORSXX BAND
Ask Rapid.Space operators to supply and request the correct services.
Warning: Please do not plug or unplug the POE RJ45 cable from the ORS while injector is powered on.
Doing otherwise might break some electrical components inside the ORS. Even if the ORS has been manually powered off through SSH (for those having root access) you still need to follow this procedure to unplug it.
Use a hexagonal screwdriver to remove the 8 screws from the enclosure.
If you have a new enclosure (Enclosure V4) compatible with the new 2 x 1W PCBs, apply thermal paste and thermal sheet this way:
If you have an old enclosure (Enclosure V3) compatible with the 2 x 0.5W PCBs, apply thermal paste and thermal sheet this way:
Warning: Make sure PCB and enclosure match, new PCB v4 will break if put inside an old enclosure !
Install the SDR main board with M2.5 screws * 17. Start by very lightly screwing all screws, then once all screws are placed tighten them all. Write down the PCB board number.
Take out the LED wires and close the ORS lid while cutting excess metal wire, as small metal bits landing on PCB could break it. Cut a red and black wire of 23cm for the PC supply, and strip and tin around 4mm at each side.
Connect the LED wires and the PC supply cables in a PTSM connector. The metal wires should not stick out of the PTSM, cut them if necessary. Use a SIM pin to open the PTSM connector in order to insert the cable into it as shown on the image.
Twist the power supply wires
Plug the PTSM connector from the LED wires in the SDR main board. Plug an armored RJ45 cable between the ORS power input and the PCB power input. If the RJ45 cable is too long, use an insulated cord to hold it in place.
Please remove the plastic films before you plug the coax cables.
This is how to install RF coaxial cables on old enclosures. (procedure needs to be updated for new V4 enclosures)
Twist the 3 RF coaxial cables by first twisting them in the vertical plane, then the horizontal plane. Don't use pliers or tools that could break the cables, they are fragile.
This is how to install RF coaxial cables on old enclosures. (procedure needs to be updated for new V4 enclosures)
Plug the 3 RF coax cables. Remove the black cable sleeve on the Radio 2 as shown on the image. First put Radio 2 cable, then Radio 1, then GPS. The connector on the boards are fragile, please be careful.
On the other part of the enclosure, install the Single Board Computer with the M3 screws. Please remove the plastic from the bottom of SBC before you paste. Fix it with 4 screws (14cm)
Install the DDR4 SODIMM, the MSATA SSD and the PCI Express adaptor board.
Set the jumpers on the SBC.
Please put the enclosure with SBC and the other side on the same plane like the figure shown. Connect the power cable to the SBC.
Warning: If the power cable is plugged in the wrong order or to the wrong port you will break the PCB !
Connect the power cable in a PTSM connector and plug this connector in the SDR main board.
Connect the ribbon FFC between the PCI Express adaptor board and the SDR main board.
Connect the second RJ45 cable between the SBC and the SDR main board.
Before closing the ORS, please be 100% sure all this is correct:
Before closing the ORS, you can blow some compressed air on the PCB to make sure there are no metal dust on it. Also write down the PC serial number. Close the enclosure and connect the PoE cable to start the system.
Place a "ORSXX" label on the interior of the case of the PC, and on the exterior of the case as shown on the images
Power on the ORS.
root@laptop:slapos-device-configuration/cli# ./update_ors.sh ORSIP
Make sure there are no errors during this process
Follow one of these tutorials depending on your case:
Replace ORS_PRODUCT and ORS_SERIAL in the following commands:
root@orsXX:~# cd ors-ssd-utils/eeprom
root@orsXX:~# apt install libftdi1-2 libconfuse2
root@orsXX:~# sed -i 's/^product=.*/product="ORS_PRODUCT"/g' config.txt
root@orsXX:~# sed -i 's/^serial=.*/serial="ORS_SERIAL"/g' config.txt
root@orsXX:~# ./eeprom -w
root@orsXX:~# ./ftdi_eeprom --build-eeprom ./config.txt
root@orsXX:~# ./ftdi_eeprom --flash-eeprom ./config.txt
# Then, in order to check the flash is OK, you can do:
root@orsXX:~# ./ftdi_eeprom --read-eeprom ./config.txt
root@orsXX:~# xxd eeprom.bin
Clone the ors-util repository:
root@orsXX:~# git clone https://lab.nexedi.com/nexedi/ors-utils.git
root@orsXX:~# cd ors-utils/uicc
root@orsXX:~# make
Execute this command:
root@orsXX:~# ./write-sim-card ORS_NUMBER
Once the first SIM card is plugged, press the Enter key
Wait until all the transfer is done, then put the next sim card, and press Enter key again. Do this for all 5 SIM cards.
Test that each SIM card can connect to the ORS by putting it in a UE. Please also test the UE can connect to the ORS from a distance with a good enough bandwidth, to make sure the connection between SDR board and ORS box is fine.
Poweroff the ORS
Please put labels saying "Do not hot plug/unplug" on the POE connectors before packaging the ORS.
Write down the enclosure serial number. Then put the ORS back in the enclosure box.
Arrange the Antennas, N to SMA adaptors, and ORS mount kit in the box as shown on the image.
Arrange the ORS box, RJ45 POE cable, and sim cards in the box as shown on the image.
Box dimensions: 310x220x200 mm , 3.5 kg
Before closing the package, please be 100% sure all this is correct:
Before filling the package with package fillers, please be 100% sure you did all this correctly:
Close the package once you have gone through the checklist
