Insert antenna into the Pluggable Interface Module

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

Procedure

Step 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.

Step 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

Step 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.

Step 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.

Step 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.

Step 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:

Figure 9. Insert the Micro-SIM cards

Install a Nano-SIM card into the router

This section describes how to install a nano-SIM card into embedded cellular systems. Install a nano-SIM card into the router using these instructions:

Procedure

Step 1

Press down on the top of the SIM slot cover and pull it away from the router until the top of the cover is free from the chassis.

Example:

Figure 10. Removing the SIM Slot Cover

1

SIM Slot Cover

Note

 

You may use a flat-head screwdriver to press down on the cover; however, ensure the screwdriver does not protrude into the router.

Step 2

Remove the SIM slot cover from the chassis.

Example:

Figure 11. Nano-SIM Slot and Component Identification

1

SIM Slot Cover

2

Nano SIM 1

3

Nano SIM 0

Caution

 

Do not touch any part of the exposed printed circuit board (PCB) area while the nano-SIM cover is removed.

Note

 

Ensure the nano-SIM cards are inserted properly into the slot connector and are not wedged between the slot connector and the chassis opening, where they could be inserted incorrectly. Incorrect insertion may cause damage to the board and/or the nano-SIM card.

Step 3

Insert the nano-SIM cards into their respective slots as indicated by the orientation indicators on the chassis. To install a card, insert the nano-SIM card into the slot until it clicks and locks into the push-push connector. To remove the card, press the SIM card further into the slot until it clicks, then release it. The card will partially eject from the slot.

  1. SIM 0: Bottom slot

  2. SIM 1: Top slot

Example:

Figure 12. SIM Slot and Orientation Indicators

1

Nano SIM slot 0

2

3

Nano SIM slot 1

4

It is recommended to use industrial-grade SIM cards for these routers.

Step 4

Install the SIM slot cover by aligning the bottom securing tabs with the holes in the chassis. Then, press the top of the cover into the snap feature in the chassis.

The nano-SIM card is installed, and the router is ready for operation.
