Important notice
This device, like any wireless device, operates using radio signals which cannot guarantee the transmission and
reception of data in all conditions. While the delay or loss of signal is rare, you should not rely solely on any
wireless device for emergency communications or otherwise use the device in situations where the interruption
of data connectivity could lead to death, personal injury, property damage, data loss, or other loss. Casa Systems
accepts no responsibility for any loss or damage resulting from errors or delays in transmission or reception, or
the failure of the Casa Systems 5G High Power mmWave Outdoor CPE to transmit or receive such data.
Safety and hazards
Warning –
Do not connect or disconnect cables or devices to or from the SIM card slot or Ethernet port in hazardous locations such as
those in which flammable gases or vapours may be present, but normally are confined within closed systems; are prevented
from accumulating by adequate ventilation; or the location is adjacent to a location from which ignitable concentrations might
occasionally be communicated.

4Site assessment pre-screen
At the distribution centre, the telecommunications provider should check site and local area coverage/tower
locations to determine suitable site install locations. This can be done through the telco’s tower database,
modelling data, and satellite maps. The operator may provide data from the pre-qualification system, but this is a
guide only as to possible best sides of the property to install the device. You should still conduct a site survey to
obtain the best signal.
5Preparation before attending customer
premises
To minimize the time spent at the customer’s premises, and depending on the specific requirements of each
installation, you might consider performing the following before arrival.
⚫Most importantly, you should ensure that the Installation Assistant and the smartphone used to perform
the installation have enough battery charge to allow you to complete the installation.
⚫Ensure that the smartphone to be used for the installation has the latest version of the Aurora app
installed.
⚫If you are going to use the CPE device as the survey device, you can unbox it and affix it to the survey pole.
⚫You can insert the SIM card If the CPE has not already had it inserted.
6At the customer premises
6.1 Installation site inspection
Review the suitability of the suggested installation locations as determined from the site assessment pre-screen
at the telco distribution center and consider any other suitable new locations.
Consider routing of Ethernet cable and location of PoE inside premises as part of suitable installation location
criteria.
Note suitable installation locations for “Site Survey”.

6.2 Ethernet / SIM cover assembly and SIM card
insertion
The AurusAI Ethernet / SIM cover must be properly attached to prevent dust and water from entering the
AurusAI’s housing. The steps to follow will depend on whether the unit you have received has had the SIM card
pre-inserted at the distribution centre.
Note –
To prevent the AurusAI from moving and potential damage to the unit, we recommend leaving the AurusAI in the pulp packaging
when preparing it.
6.2.1 Preparing a unit with a pre-inserted SIM card
Assemble the Ethernet cable gland as shown below when finalizing the installation.
Figure 3 –Ethernet cable gland assemblyl
When performing a site survey, loop the survey cable around the hook which is attached to the mounting
bracket to provide strain relief. The hook can be removed from the mounting bracket and disposed of
thoughtfully when the site survey is complete.

6.2.2 Preparing a unit requiring SIM insertion
Units shipped from the factory without a SIM card pre-inserted require the installer to remove the Ethernet /
SIM card cover and insert the SIM card. The Ethernet cable gland comes shipped in a separate bag and must be
assembled at the end of the installation.
1Using an M4 Phillips head screwdriver, remove the screws that secure the Ethernet / SIM card cover.
Remove the Ethernet / SIM card cover and SIM card retaining clip.

3Push the SIM card in until it locks into place. You will hear a click when the SIM card is locked in place. You
may need to use tweezers or something similar to assist in pushing the SIM card all the way in.
4Replace the SIM card retaining clip and Ethernet / SIM card cover then re-tighten the screws. The screws
should be tightened with a torque driver to 0.4Nm.

5If you are using the customer unit for the site survey, connect the survey cable to the Ethernet port. Loop
it around the hook attached to the mounting bracket to provide strain relief.

mmWave Antenna location
(when in the ‘home’ position)
7Installation considerations
As the 5G High Power mmWave Outdoor CPE is aligned specifically for each individual property, please take note
of the following when installing the equipment:
⚫After alignment, do not move, place anything in front of, or adjust the position of the 5G High Power
mmWave Outdoor CPE since this will likely have a negative impact on the signal quality and performance
of the wireless service. When the antenna is in the ‘home’ position, the mmWave antenna is located as
shown below.
Figure 12 - mmWave Antenna location
⚫Keep the AurusAI away from trees, branches and power lines or communications cables.
⚫The Antenna Power Supply (30W PoE Injector) and Wi-Fi Gateway must be installed in a well-ventilated
area and near a dedicated power outlet which allows easy visibility of the indicators.
⚫If construction work has been carried out on the exterior of the property, the antenna may need to be re-
aligned to ensure the installation is still operating at peak performance.

8Site survey
8.1 Overview
To perform a site survey, you will need to mount the AurusAI to a survey pole and carry it around the site with
both the Installation Tool and a smartphone.
1On the ground, mount the AurusAI to the survey pole.
2Connect the Installation Assistant to the AurusAI via the survey cable and ensure power is being delivered.
3Load the Aurora App and begin survey so that the app is indicating signal strength.
4Perform the site survey with everything connected and operating and locate the position with the best
signal strength.
8.2 Performing a site survey
8.2.1 Mounting the AurusAI to the survey pole
Attach the AurusAI to your survey pole. We recommend a pole of approximately 1.5 metres in length. To fix the
AurusAI to the survey pole, follow the instructions in the Assembling and attaching the AurusAI to the mounting
bracket section. Ensure that the AurusAI is properly secured to the survey pole so that it does not come off the
during the site survey.
8.2.2 Connecting the Installation Assistant
Connect one end of the included 3 metre Ethernet cable to the power supply port of the AurusAI then connect
the other end of the cable to the CPE (blue) port on the Installation Assistant. Take up any slack in the cable so
that it does not present a tripping hazard. You can use the Velcro strap attached to the Installation Assistant to
help hold the cable in place.
8.2.3 Loading the Aurora Installation App
On the smartphone that you will use for the installation, open the Aurora Pro installation app.
When the app opens, the Casa Systems splash screen is displayed and then the Let’s get started page.

To commence the site survey for a new customer, tap on the New Device button. For further instructions on
how to perform the site survey using the app, refer to the Aurora Installation App User Guide (document
UG01271).

8.2.4 Performing the site survey
When you have the Aurora app at the point where it is ready for you to perform the site survey, you should walk
around the installation site holding the AurusAI on the survey pole along with the Installation Assistant and
smartphone and find the location with the best signal. The Aurora app provides both a visual cue through bars
indicating RSRP for each cellular technology type as well as an audible beep which increases in frequency as the
5G signal gets stronger.
Figure 13 - Performing the site survey
When walking around the site, you should also rotate the AurusAI to locate the best signal since the AurusAI will
not automatically swivel during the survey. When you have found the most suitable location, taking into
consideration the signal strength and the aesthetics of the installation location, remove the cable from the
Ethernet port of the AurusAI and remove the AurusAI from the survey pole. Mount the AurusAI in accordance
with the steps in the next section.

9Mounting the AurusAI
9.1 Removing the locking pin
Before proceeding any further, you must remove the locking pin from the unit. You can perform this task while
on the ground to reduce time spent on the roof/ladder.

3Replace the locking pin screw cap to the bottom of the AurusAI, turning it clockwise so that it is secured
tightly to ensure that there is no water or dust ingress.
