The following standard tools may be needed during the installation.
| Marker pen | Percussion drill | Cross screw driver | hammer |
NOTE: Other accessories have been packed in the packing box.
Construction Safety
1. The installation personnel must master the basic safe operation knowledge, through the training, and having the corresponding qualifications.
7
2. Before installation, the installation personnel must be prepared with safety protection, such as: safety helmet, safety belt, reflective clothing, gloves, and safety shoes, etc.
3. Before installation, the installation personnel must cross-check each other to ensure above preparations have done.
Installation Environment
To get the signal coverage effect best, please place the Neutrino base station in an unobstructed space.

3.Installation
Ceiling or Wall Mounting
Attention:
• The thickness of ceiling is not less than 18mm, and bearing more than 5kgs. If the strength is not suitable, the device maybe fall off.
• If the ceiling is made of unstable material, such as gypsum, this ceiling installation is not recommended. If the device must be installed on ceiling due to environment restriction, add one layer better panel under screws to make sure the device is fastness.
Here take mounting on wall as an example, mounting on ceiling is the same as it.
1. Put the bracket against the wall and mark the position, and then drill three holes. Later install expansion pipe, bracket and tighten with screws.
2. Install four screw bolts on the back of the gNB and tighten these screw bolts.
3. Install the bracket on the back of the gNB with screws and tighten these screws.
9
4. Put the gNB from top to bottom along the slot and push it to the bottom, and then clamp the spring sheet.
Connect Cables
1. Connect power adaptor to PWR port and the other end connects to AC power.
2. Connect Ethernet cable to WAN/POE++ port and the other end connects to the web client.
When the installation site has POE switch, the POE++ supply can be adopted.
The POE switch should meet the POE++ requirements for the BT protocol, with a power of 30 watts or higher.
3. Connect optical fiber to SFP port and the other end connects to the gateway device.
4. (optional) Connect ANT0/ANT1 to external antenna with SMA connector. By default, the built-in antennas are used.

Power on to Check LED Status
Power on the gNB, and wait a few minutes while the gNB boots up. Per the previous Table 1-2 in “1.3 Appearance”, check that the LED indicators are lighting as expected.
