Installing the Apex Strand
RF provisioning
1.
Before applying power to the Apex Strand, a qualified technician should verify
transmit levels at the tap location.
2.
Determine target transmit levels based on the specific installation location.
3.
Verify transmit level of the cable modem is in the range of +35 to +51 dBmv.
Connect the power source
1.
Connect the power cable (hardend coax line) to the Apex Strand unit. Ensure the
weather sealing of the outdoor housing connector per local installation guidelines.
2.
If you are using a Kill Switch in your installation, connect the Kill Switch 3 pin
connector cable to the Apex Strand alarm connector input (see Figure 1-3).
3.
Install the fuse inside the Strand unit.
4.
Close the cover to the Strand unit and tighten the bolts based on the torque
recommendations (see “Closing and sealing the enclosure” on page 1-17).
5.
Move away from the Strand unit to a safe distance and reconnect the power to the
work area.
6.
Verify the power LED status on the Kill Switch and/or on the Apex Strand.
Verify the Strand Operation
1.
Once AC power is applied to the Apex Strand, verify that the Green LED on the
side of the unit is lit (see Figure 1-4). Wait several minutes for the Apex Strand to
boot up and make an attempt to make a data connection to the HFC.
2.
Coordinate with the operator's NOC to bring up the data connection to the Apex
Strand, which may require adjusting the attenuation settings. The Apex Strand
ships with a 0dB attenuator installed. It is up to the NOC and the installer to
achieve the optimal signal level.
3.
Once the NOC has verified that you have a connection to the Apex Strand's cable
modem, and that it can recognize a CPE and verify the CM status LED is green.
4.
The LTE unit is ready to connect to the Sprint network.

Closing and sealing the enclosure
All Apex Strand enclosures are weather and electronically protected using both an
Environmental and EMI rubber seal integrated into the enclosure halves. Retention
bolts are held in place by lugs on the outside of the enclosure.
Torquing the Apex Strand bolts
Using an open-end 1/2 inch wrench or socket, tighten the bolts on the Apex Strand to
a final torque of 50 in lbs/5.6 Nm in the sequence shown in Figure 1-11.

System management
The Apex Strand Small Cell is designed for remote system management via the
AeMS. In case of loss of network connectivity the unit supports some diagnostic
service via on board Wi-Fi.
The Apex Strand appears as a CM and a CPE device in the HFC network. The internal
CM connects to the HFC network as a standard device.
