Installing the drop cable and LPU
Perform this task to install the drop cable from the ODU to the PoE power supply, and to
provide grounding and lightning protection for the installation.
This task consists of the following procedures:
• Preparing drop cables on page 5-16.
• Assembling an RJ45 connector and gland on
page 5-17.
• Installing and grounding the main drop cable on page 5-19.
• Connecting an RJ45 and gland to a unit on pa
ge 5-20.
• Disconnecting an RJ45 and gland from a unit on page 5-22.
• Making a drop cable ground point on
page 5-23.
• Installing and grounding the drop cable at building entry on
page 5-27.
The drop cable and ground cable installation must meet the requirements defined in
Grounding and lightning protection on page 2-15.
To provide effective protection against lightning induced surges, grounding cables must be
installed without drip loops and pointing down towards the ground.
To avoid damage to the installation, do not connect or disconnect the drop cable when
power is applied to the PoE power supply.
