ASSIGNMENT FRONT PANEL LABELLING – SOFTWARE
- The ports and LEDs “LAN 1” to “LAN 5” correspond respectively to the interfaces “eth0” to “eth4”
- The LEDs “WLAN 1” / “WLAN 2” and “LTE 1” / “LTE 2” refer to WLAN and LTE modules
- WLAN modules are called “radio” within the software
- LTE modules are called “modem” within the software
- The purpose of the antennas depends on the modules inserted in your CyBox model
LED INDICATORS

RESET SWITCH
The CyBox RT 2-A is equipped with a hidden reset switch behind the front
panel, which is located beside the service cover. The button is accessible
with a straightened paper clip pushed through the little hole on the front
panel. The effect of pressing the reset switch depends on the duration of its
activation, as indicated in Table 10 below. The time response is valid only if
the device has completly booted (after approx. 1 min). While the device is
booting or executing U-Boot, pushing the button will always reset the device.
The following table describes the functions of the reset switch.

SIM CARDS
The CyBox RT 2-A provides 2 SIM slots per LTE modem. Only one slot per modem
can be active at any time. To install SIM cards the service cover has to be
removed using a suitable torx 10 screwdriver. After installing the SIM cards
the service cover must be closed and the screws tightened to a maximum torque
of 0.55 Nm. The indexing of SIM slots is software dependent and can be
selected via an SNMP command or using the web interface.
Note: Switching between SIM slots takes about 30 seconds, slot 1 being
preselected at power up. If you plan to use only one SIM card for a given LTE
modem it is advisable to use slot 1 to avoid slot switching delay during
booting.
The drawing in Figure 5 shows the SIM slot assignment per modem.
Important: Do not change the SIM cards when the device is powered.
MOUNTING
When mounting the CyBox RT 2-A please take the following aspects into account.
- Do not install the device close to any sources of heat such as radiators or heat registers.
- Keep the device away from any liquids and avoid exposure to dripping or splashing. The protection class of the housing is IP40.
- Keep a free space of at least 150 mm around the housing to ensure adequate heat dissipation capabilities.
- For optimal heat dissipation the connectors should face down.
- The housing provides four mounting cutouts to install the device in horizontal or vertical orientation on a flat and stable surface.
- For fixation use M6 screws of sufficient length with additional M6 washers.
The drawing in Figure 6 shows the outer dimensions of the housing including the position of the mounting cutouts.
CONNECTING AN EARTHING CABLE
A M6 earthing stud on the front panel of the device (also refer to Figure 3) for protective earth connection is essential for the device security. Carry out the following steps to connect an earthing cable.
- Use an earthing cable with a cross-section of at least 2.5 mm² and a wire end sleeve with eyelet suitable for a 6 mm threaded bolt.
- Mount the earth cable as shown in Figure 7.
- Fasten the cable by tightening the nut to the required torque (recommended according to EN60947-1 are 3 Nm).
Earth Cable Mounting on Earth Stud
ELECTRICAL CONNECTION
- Make sure the device is properly grounded.
- Establish a connection to the network by plugging an RJ45 patch cable to one of the front panel RJ45 connectors.
- Connect the desired number of antennas to the device. Each radio/modem can use up to three antennas for maximal performance. LTE modules are intended to be connected to two antennas and an additional GNSS antenna connector.
- In case of using a local power supply the appropriate wiring (see Table 1 ) must be established to connect the power line to the device.
- Make sure that the voltage of the power supply conforms to the voltage on the type plate.
- Ensure that the power supply is grounded correctly and that the power cable is intact and undamaged. Do not switch on the system if there are damages on the power cable or plug.
- Use power cables which are approved for the power supply in your country.
- The device itself has no on/off switch, it starts as soon as it is supplied with power.
