Procedure

1.

Insert and then gently push the Cellular pluggable into the pluggable slot of C8151-G2 or C8161-G2 until firmly fixed.

Example:

Insert antenna into the Pluggable Interface Module

To insert the antenna in the Pluggable Interface Module, perform these steps:

Procedure

1.

Insert and tighten antennas in the antenna slots as per the sequence mentioned in the figure.

Example:

Figure 7. Attaching the antennas
Note

You need to install antennas as per the sequence to get enough space to tighten antennas in all the antenna slots.
2.

After installing the antennas, adjust the antenna orientation by spacing out each of them equally until they are spread out. This is significant as it helps in getting higher RF performance.

Example:

Antenna connector details for embedded 5G devices

The antenna SMA connector (labeled as #3) enables connection to an external antenna, optimizing 5G performance on the C8151-CVAI-G2 and C8151-CVAP-G2 devices, as shown in the image.

Insert Micro-SIM into a Pluggable Interface Module

This section describes how to insert a Micro-SIM card into a Cellular Pluggable Module. To insert the Micro-SIM cards into a Cellular Pluggable Module, follow these instructions:

Procedure

1.

Place the pluggable module on its bottom side, remove the SIM door screw, use a #1 Philips screwdriver for removing the screws, and then carefully remove the Micro-SIM cover from the pluggable module.

Note

Ensure to use the correct tool for removing the Micro-SIM door.
2.

Slot 1 and slot 0 are the Micro-SIM slots.

Caution

Do not touch any part of the exposed PCB circuit area when the Micro-SIM cover is removed.
3.

Install SIM 0 and SIM 1 in their respective slots. SIM 0 or SIM 1 is marked on the pluggable interface module above the Micro-SIM cover. The SIM icons show the correct orientation required to install the SIM into each respective connector (SIM connectors are a push-push type). To install, insert the SIM card in the connector until you feel it click, then let go and the SIM is locked to the connector. To remove the SIM card, depress the SIM in the connector slot again until you feel the same click and let it go; the SIM connector should eject part way out of the connector. The SIM card can then be grabbed and removed. Secure the Micro-SIM cover with a screw, use a number 1 Philips screwdriver to secure the screw on the Micro-SIM cover. The recommended torque is 2.8 - 3.8 inch LBF.

Note

We recommend using industrial-grade SIM cards.
4.

You have now successfully inserted the Micro-SIM cards into the Cellular pluggable module. The marking on the Mirco-SIM door should align with Micro-SIM 0 on the pluggable module with the arrow pointing upward.

Example:
